FreeMind on Linux

From FreeMind

Jump to: navigation, search


Installation (0.8.0)

FreeMind is a Java program, hence you need Java to make it work. There is the "Java runtime engine" (JRE or J2RE) required to run (use, start) FreeMind, and there is the "Java Development Kit" (JDK or J2DK) if you want to compile FreeMind (If you don't know what compile means, then you need only the JRE. In the following lines, I will concentrate on making FreeMind run and the JRE installation).

Once Java has been installed, only then does it make sense to install FreeMind. You can use packages (.deb or .rpm), which is a bit more work to setup but much easier to update, or you can use the more simple installation from a ZIP file (as described in the UN*X section).

The Debian installation

This description should be valid for any Debian based distribution, in particular (K)ubuntu.

FreeMind 0.8.0 is not part of the Debian repository, although FreeMind 0.7.1 is, because of a lot of additional dependencies, and some license issues. For all the gory details, have a look at [1] from the Debian Wiki. We're working on it, but it will take time and won't happen before release of FreeMind 0.9.0.

Install Java the Debian way

Most easiest way

Make sure that the Java 5 JRE under Debian resp. Java 5 JRE under Ubuntu (FreeMind 0.8.0 doesn't support Java 6) is installed, using e.g. aptitude install sun-java5-jre (for Sarge, you will need to add first the backport repositories).

You can make Java 5 the default JRE by using the command update-java-alternatives -s java-1.5.0-sun, but you don't need to.

For Debian versions older than Sarge, or if you need Java 1.4

As Java isn't really free or open, there was no official Debian package for it. The procedure is hence to install java-package from the contrib section, e.g. as root with:

# apt-get install java-package

Read the instructions delivered with the package, and create your own little Java package(s).

In a nutshell, download the Java Runtime Environment (JRE) from Sun (Linux self-extracting file), called something like j2re-1_4_2_10-linux-i586.bin or jre-1_5_0_02-linux-i586.bin. Use the command from the java-package called make-jpkg along with fakeroot as in:

$ fakeroot make-jpkg j2re-1_4_2_10-linux-i586.bin

noting that the filename depends on your version. When you have this, you can install the package as root:

# dpkg -i sun-j2re1.4.deb
The package sun-j2re1.4debian is no longer needed since Sarge has been released.

Installing FreeMind under Debian

You can always download the required .deb files from the Files section and install them by hand, using dpkg or whatever, but the comfortable way is to add the following lines to your /etc/apt/sources.list:

   deb <version>/
   deb-src <version>/
you need to replace <version> by either unstable or experimental: I use unstable for software for which I'm pretty sure it could make it into the official Debian repository, experimental for the rest. Currently, unstable contains FreeMind 0.8.0 and dependencies, experimental contains betas of 0.9.0 (and dependencies).

Then call as root the two (or three) following commands:

# apt-get update
# apt-get install libbatik-java/testing libjcalendar-java/testing
# apt-get install freemind/experimental freemind-plugins-svg/experimental \
      freemind-plugins-time/experimental freemind-plugins-help/experimental \

(it's more comfortable because, each time you call "apt-get upgrade", you'll get automatically the new freemind package)

Some additional notes:

  1. with the repository method, you can get as well the sources for the .deb package using "apt-get source freemind[...]".
  2. of course, you're not obliged to install the different plugins.
  3. if you want to use the 'help' plugin, you'll need to download JavaHelp from Sun's Java site and install the jar file as /usr/local/share/java/jhall.jar.
  4. the 2nd line is only required if you're using "sarge" and want to install freemind-plugins-svg (Batik) respectively freemind-plugins-time (JCalendar). For this command to work, you need of course to make sure that the proper repositories have been entered in /etc/apt/sources.list, like in:
   deb testing main contrib non-free
   deb-src testing main contrib non-free
XX has to be replaced with the nearest country code (e.g. de for Deutschland, fr for France,...; check the Debian worldwide mirror sites list).
libforms-java has been recently replaced through libjgoodies-forms-java and is now part of Debian etch/testing.

Ubuntu & Kubuntu

2010/10/06 - The following is no longer true on 10.04. Just installed FreeMind via the repositories on Kubuntu 10.04 and the version is 0.9.0 RC 6.

An outdated and buggy Freemind is included in Ubuntu multiverse repositories (enable multiverse in Software Sources), though it's a one-click install.

If you get an error when you try to run freemind about not being able to open libgtkpeer then use the following command line:

    • sudo apt-get install gcj-jre

Alternative, More updated Repository

Start the Synaptic Package Manager (under the System menu), and then do the following:

  • Add the following repositories using the Menu <tt>Settings ⇒ Repositories:
    • deb unstable/ ("Third Party Software" tab)
    • deb ubuntu/ ("Third Party Software" tab)
    • The multiverse and universe repositories ("Ubuntu Software" tab)
  • "Reload" the package list using the corresponding icon.
  • Mark the following packages for installation (or make sure they are already installed):
    • sun-java6-jre.
    • javahelp2
    • freemind
    • And, as you need them, freemind-plugins-help, freemind-plugins-svg and freemind-plugins-time (you might search for "freemind" and install everything you find...).
  • Apply the changes. That's it, FreeMind appears under the "Office" sub-menu!
Note 1 
I've added the libbatik-java package under my personal ubuntu repository, be aware that (security) updates might not happen timely. It shouldn't bother anybody much, but just in case...
Note 2 
Ubuntu's online documentation explains Synaptic and how to add extra repositories.
Note 3 


Synaptic shows JAVAHELP2 has been packaged. When you search for JAVAHELP, you may see javahelp2 - the 2 is a version number).

Synaptic shows FreeMind 0.8.1 has been packaged.

FreeMind 0.8.0 doesn't work properly with Java 6.

0.9.0.betaX is not yet packaged, check therefore the UN*X installation method

Old instructions

Installation on Ubuntu requires two steps. Install a Java runtime environment, then install FreeMind. Newer versions of Ubuntu (since 6.10?) install Java by default. So chances are that you can skip most of the following instructions. You might want to check, if Java is installed and what version is active. Open a Terminal and type

   java -version

Here's what you get with Ubuntu 9.04

user@ubuntu:~$ java -version
java version "1.6.0_0"
OpenJDK Runtime Environment (IcedTea6 1.4.1) (6b14-1.4.1-0ubuntu11)
OpenJDK Server VM (build 14.0-b08, mixed mode)

Java 1.4 or higher should be fine. See also Ubuntu's community documentation on Java.

Install Java Manually

These instructions (and these notes) are also known to work on Ubuntu 6.10 (EdgyEft). See the Talk Page.

I got my hand on a Kubuntu 5.10 installation, and am now able to give some hints about the specificas of the (K)Ubuntu installation:

  1. you will first need to add the multiverse and universe repositories to your installation, there are plenty of places which explain how to do this.
  2. then, if you're happy with Blackdown's Java 1.4, you don't need to create your own Java package and can install j2re1.4 from the multiverse repository.
  3. sadly, libbatik-java and libjgoodies-forms-java don't seem to be part of any repository; so, you should add the Debian repository as described in the above notes, but be careful to not break your installation with too many pure Debian packages. I personally added the following lines to the file /etc/apt/preferences:
   Package: *
   Pin: release o=Debian
   Pin-Priority: 200

You milleage may vary but if this doesn't work, consider looking at this link.

Install FreeMind Manually

All the above required packages can be installed more easily within Kubuntu 6.10, even without installing a new java RE. I used the previous installed sun java 6 jdk (Freemind 0.8 gives a error message at start, that it might not run correctly, but it does afterwards). Notice that FreeMind 0.8.0 doesn't support Java 6 (FreeMind 0.9.0 will) and issues have been reported; use apt-get install sun-java5-jre if you want to be sure.

After adding the multiverse and universe repositories add the FreeMind-specific repositories:

   deb <version>/
   deb-src <version>/

(where <version> is unstable or experimental), apt-get install freemind (plus plugins packages if needed) seems to work without adding further Debian repositories.


This worked for me on Ubuntu Feisty Fawn and was very easy.

Download the FreeMind .deb files to an empty directory. I put them in ~/Freemind.

Open a terminal window and change directory to ~/Freemind.

My directory contained the .deb files listed here:


Since I had Sun Java installed already, I just ran these command lines:

    gdebi-gtk freemind_0.8.0-1_all.deb
    gdebi-gtk freemind-plugins-time_0.8.0-1_all.deb
    gdebi-gtk libbatik-java_1.5.1-1_all.deb
    gdebi-gtk freemind-plugins-svg_0.8.0-1_all.deb

That was it. Last thing I did was to create a new launcher on my desktop that called "freemind". I dragged the launcher to the task bar where a single click launches the application. It seems to work well. I didn't bother installing the help .deb because the dependencies reported by gdebi-gtk were too complicated for me to resolve.

Good luck! I hope your installation works as well as mine.

The RPM installation

Starting with version 0.8.0 of FreeMind, I've started to orient my packaging work towards JPackage compatibility, so that the same packages should work for all distributions with JPackage's packages, especially SuSE 9.x and 10.x, Mandrake/Mandriva 10.x, as well as Fedora Core.

Installation of FreeMind 0.8.1 under openSUSE 11.2

  1. Search for msv-xsdlib on [2], install it with "1-click install".
  2. You should now be able to install by clicking on the link on Sourceforge download page, and use "1-click install".

Installation of FreeMind 0.8.1 under SuSE 10.3

  1. Add software repositories using YaST:
    1. Add URL (repomd.xml is not signed, ignore YaST complains)
    2. Add community repository Main non-OSS (for Sun's Java)
    3. Add Jpackage URL free, generic and version 1.6, using the list of JPackage mirrors, e.g.
  2. Using YaST's software management, search for 'freemind' and install what you see and like.
  3. Also using YaST's software management, make sure that java-1_5_0-sun or java-1_6_0-sun is installed (search for '-sun').
  4. And make sure that FreeMind uses the right Java (not gcj as per default).

Installation of FreeMind 0.8.1 under Fedora Core 8

  1. Add software repositories using the Package Manager (aka pirut):
    1. Add URL
    2. Add Jpackage URL free, generic and version 1.6, using the list of JPackage mirrors, e.g.
    3. Add Jpackage URL non-free, generic and version 1.7, using the list of JPackage mirrors, e.g.
  2. If you wish to use the Smart package manager, instead of pirut, create a new channel for Freemind by...
    1. Select Edit | Channels
    2. Press New
    3. Choose "Provide channel information" then press OK
    4. Choose "RPM MetaData" then press OK
    5. Provide an alias of your choice (e.g. FreeMind) and a name (really a description) of your choice. Set the Base URL to, then press OK
    6. Attempting to install the SVG plugin necessary for exporting images is a problem as the Fedora 8 Development repository is, as of 12-Feb-08, the only place I've found with the 64-bit libbatik needed by SVG, and then only version 1.7. The 0.8.1 FreeMind SVG plugin claims to want < 1.7. Installing 0.8.0 seems to work fine even with Batik 1.7. Upgrading everything except the SVG plugin seems to work, as well.
  3. Using either Package Manager, search for 'freemind' and install what you see and like (at this stage, FreeMind is installed and kind of works using IcedTea 1.7, we now assume that you want FreeMind to really properly work...).
  4. Download the JDK (not the JRE!) RPM of Java 1.5 or 6 from Sun's website, install it, then install the corresponding java-1.5.0-sun-compat or java-1.6.0-sun-compat package.
  5. And make sure that FreeMind uses the right Java (not IcedTea 1.7 as per default).

Install Java the JPackage way

FreeMind only works with Sun's or Blackdown's Java.

Taking the example of Sun's Java, there are three possibilities to install Java:

  1. It already does come with your distribution, fine, nothing to do, but make sure it's really Sun's Java by checking the output of java -version.
  2. Install java-1.4.2-sun-compat or java-1.5.0-sun-compat on top of Sun's JDK
  3. Download java-1.4.2-sun or java-1.5.0-sun, build them and install the created packages.

Install JavaHelp2 the JPackage way

JIf you want to install freemind-plugins-help, you'll need to install JavaHelp2. For licensing reasons, JavaHelp2 can't be redistributed by OpenSource distributions, hence you'll need to build the package yourself:

  1. download
  2. build
  3. and install the created RPM file.
in the mean time, JavaHelp2 has been put under GPL by Sun and can be packaged and distributed in binary form, and there is such a package coming from JPackage, to be found on a JPackage mirror. Still, the state of this package is a bit unclear, e.g. I'm not sure it's part of a repository.

Install FreeMind with RPM, the stupid and easy way ;-)

Install Sun's or Blackdown's Java the JPackage way.

Install JavaHelp2 the JPackage way if you need freemind-plugins-help.

Download all the RPMs from the Files section (don't forget jcalendar and jgoodies-forms) in a directory. Install all these RPMs using the rpm command, e.g.:

# rpm -ivh freemind*.rpm jcalendar*.rpm jgoodies-forms*.rpm

For each missing dependency, go to the JPackage site, search and download the package(s) using the same kind of rpm command. Here is a list of dependencies:

  • freemind: jakarta-commons-lang, relaxngDatatype, msv-xsdlib, jgoodies-forms, xml-commons-apis, ws-jaxme, jakarta-commons-codec
  • freemind-plugins-svg: batik, rhino, xerces-j2, xml-commons-apis
  • freemind-plugins-help: javahelp2
  • freemind-plugins-time: jcalendar >= 1.2.2
search for "msv" in order to find "msv-xsdlib". All the FreeMind RPM sources can be downloaded from [3].

Install FreeMind on Fedora 10, 11 and 12

First become root, create a temporary directory and CD to it.

There is a broken dependency at the moment in the SVG plugin so do this:

rpm --import
rpm --oldpackage -ivh

Now download all the rpms you want for freemind and put them in your temporary root directory.

There is no fedora support 10 and we are missing packages we need so.we will enable the generic repositories.

curl | awk '/-generic/,/^$/ { sub("enabled=0","enabled=1"); print }' >/etc/yum.repos.d/jpackage17.repo
yum --nogpgcheck -y localinstall freemind-*.rpm

Remove the temporary directory you made and start freemind :)

Install FreeMind on Fedora 13 (64bit)

Open terminal, and execute the following with command line.

1) Make a directory (e.g. mkdir FreeMind).

2) Download the FreeMind ANY packages into the make directory (filename: approx 8 MB).

3) unzip the all the file in that directory ([user@computer FreeMind] gunzip

4) type the following "bash" and a GUI will pop out.

That was tested with Fedora 13-64bit.

Install FreeMind using apt4rpm

method tested with SuSE 10.1 - work in progress

$ wget
(become root)
# rpm -Uvh install-apt4suse.rpm
  • call as root the install-apt4suse script (wait a while). Slightly unrelated: missing key has to be loaded usng rpm --import
  • add the required JPackage entries as described under and linked pages. (one need to import the Jpackage GPG keys using rpm and gpg!)
  • add etc... and the rest same as below
  • apt-get update
  • download and build javahelp2: apt source javahelp2 + download from Sun, then install with rpm.
  • apt install freemind\*

method tested with SuSE 9.2

It sounds easy but actually the first step can be a bit tricky: you first need to setup apt4rpm, as described following the links given in this Jpackage Repository page. The good news is that always more distribution are coming standard with apt on board (if you are able to call apt-get as root, you already have it).

Add the JPackage repository to your /etc/apt/sources.list file as described in the same above page. Add also the two following lines (the 2nd one is optional, for sources) to the same file:

   rpm noarch java
   rpm-src noarch java

Then call as root the two following commands:

# apt-get update
# apt-get install freemind freemind-plugins-svg freemind-plugins-time freemind-plugins-time

(it's more comfortable because, each time you call "apt-get upgrade", you'll get automatically the new freemind package)

Some additional notes:

  1. with the repository method, you can get as well the sources for the .rpm package using "apt-get source freemind[...]".
  2. of course, you're not obliged to install the different plugins.

Install FreeMind using urpmi

method tested with Mandriva 2006

Use Easy Urpmi to setup a first set of urpmi repositories. Then add the JPackage repositories. See JPackage Project Repositories for details, but in a nutshell:

# urpmi.addmedia jpackage-1.6-generic MIRROR/1.6/generic/free with
# urpmi.addmedia jpackage-1.6-generic-non-free MIRROR/1.6/generic/non-free with

Install Sun's or Blackdown's Java the JPackage way.

Install JavaHelp2 the JPackage way if you need freemind-plugins-help.

Add FreeMind's repository:

# urpmi.addmedia freemind

As of Mandriva 2008 this does not work as the urpmi.addmedia requires a hdlist file. Using the --no-probe does not work.

And then install FreeMind and its plugins:

# urpmi freemind freemind-plugins-svg freemind-plugins-time freemind-plugins-help

The Gentoo installation

Install Java the Gentoo way

Basically, simply do the following:

# emerge -av virtual/jdk

See the Gentoo Java Guide for more information and further instructions.

Install FreeMind the Gentoo way

To ensure you are up-to-date in portage:

# emerge --sync (or emerge-websync)

The latest version of FreeMind in Portage may be masked. To use this "unstable" version you may have to unmask the package.

To make sure you know what is going to install, use the --ask flag to emerge. Answer `yes' if you want to emerge dependencies:

# emerge --ask app-misc/freemind

On any UN*X kind of system (also Linux)

Install Java on UN*X

It doesn't really matter, just install some Java from Sun or Blackdown. Download the Java Runtime Environment (JRE) from Sun (Linux self-extracting file), called something like j2re-1_4_2_07-linux-i586.bin or jre-1_5_0_02-linux-i586.bin, or from Blackdown.

Before doing anything though, check to see if a usable Java is already on the system. Any Solaris (version 9 or newer) has one, for example.

Install FreeMind on UN*X

straight-forward installation method

Download the file called something like (or if you don't need the plugins), create somewhere a sub-directory and unpack there the file (as normal user or root, depending where you created the sub-directory):

$ unzip .../
$ chmod +x

You're done, on any system where /bin/sh is a POSIX-compliant shell. That's true on most Linux systems, but not on Solaris. On Solaris, edit the first line of and change /bin/sh to /bin/bash. Now you're done.

NB: If you want to use beta 0.9: There are zip-Files available for 0.9, too.

more subtle installation method

Considering you're installing FreeMind locally, you should get root and do the following:

# mkdir -p /usr/local/share/freemind
# unzip freemind*.zip -d /usr/local/share/freemind
# chmod +x /usr/local/share/freemind/
# ln -s /usr/local/share/freemind/ /usr/local/bin/freemind

Here's a video of the process: total time ~3 minutes.

This will copy the contents of the zip file to /usr/local/share/freemind and create a symbolic link to the FreeMind script in the /usr/local/bin directory.

The link to the script will only work if you unzip FreeMind in a directory for which is searching. You can however install FreeMind in any directory (e.g. in /opt/FreeMind) if you set $FREEMIND_BASE_DIR in /etc/freemind/freemind.rc resp. ~/.freemind/freemindrc like this:

# path to the installation directory of FreeMind

Starting FreeMind

Installed from RPM or DEB package

Just type "freemind" in a console or an Alt+F2 command line, you're normally done. There should also be a menu entry under "Applications" in KDE and GNOME (under Debian, in any window manager).

Installed from ZIP file

You'll need to use a console, or the Alt+F2, or create your own menu entry, using one of the following commands:

       $ /some/directory/path/
  • if you've used the #more_subtle_installation_method, and assuming /usr/local/bin is in your PATH variable, you can use a simple freemind command, as if installed from a package.

Frequently and less frequently Asked Questions

FreeMind aborts with an 'xcb_xlib' error

When trying to start FreeMind, it aborts with an error as follows:

java: xcb_xlib.c:52: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.

This is a known Java error and one possible solution is to set the following environment variable:


(helps on SuSE 10.3)

On gentoo, the following command line fixes the issue:

locate|grep /opt/sun-j.*/lib/i386/.*|xargs sed -i 's/XINERAMA/FAKEEXTN/g'

For 64-bit:

locate|grep /opt/sun-j.*/lib/amd64/.*|xargs sed -i 's/XINERAMA/FAKEEXTN/g'

I can't paste branches copied from FreeMind into other applications

Try to use the middle mouse button to paste the content copied from FreeMind.

Under KDE, you can use klipper and set the option "Synchronize contents of the clipboard and the selection", so that you can also use Ctrl+V or Shift+Ins to paste.

I want to add an icon for my Link to FreeMind on my Desktop. Is there one?

The icon is compressed inside the freemind.jar file you can find in the FreeMind installation directory, e.g. /usr/(local/)share/freemind. Once the file located, use a command similar to:

$ unzip $FREEMIND_BASE_DIR/lib/freemind.jar \*/FreeMindWindowIcon.png -d /tmp

This will create a folder images in the tmp directory containing the FreeMindWindowIcon.png file - your icon!

When starting FreeMind, it says "java: command not found". What's wrong?

It's a problem from Fedora Core, Mandrake and the Java Sun RPM, which neither add the java command to the PATH nor defines properly the variable JAVA_HOME.

Add the following two lines to one of the startup scripts (/etc/profile and/or /etc/bash.bashrc for all users, or $HOME/.profile and/or $HOME/.bashrc only for you):

   export PATH=$PATH:/usr/java/j2re1.4.2_04/bin
   export JAVA_HOME=/usr/java/j2re1.4.2_04

(the part in italic depends on your installation)

Why do I get a "No print service found" whenever I attempt to print?

At least up to version 1.4, the java runtime under Linux is using the BSD printing system (also known as the lp commands, or old lp). Most modern distributions offer the CUPS printing system, which needs a compatibility layer to work with Java:

  • Under SuSE 8.2, the package required is called cups-client
  • Under Debian, it's called cupsys-bsd. Sun's Java 6 (package sun-java6) needs the package libcupsys2. I addition to this you got to have a ServerName line in /etc/cups/client.conf.

Install this package and you should be able to print from FreeMind.

If problem persist, try this [4].

If CUPS is not installed on your system, it is easier to install the traditional lpr/lpd system. On Debian, the package is just lpr, apt-get install lpr should be enough.

Sun's Java 1.5 supports CUPS out of the box. If, however, printing still doesn't work it may be because the CUPS printer names contain '-' characters. There's a Java bug that prevents this from working properly [5], and it doesn't seem fully fixed yet (build 1.5.0_06-b05). Work-arounds are:

  1. Rename printers, e.g. from "my-printer" to "myprinter".
  2. Network printer: Add a local CUPS network printer with a simple name without '-'s in it and use the CUPS URI reported by lpstat -v for the printer you want.
  3. After executing "$ls -l /usr/lib/" if there exists a link as "/usr/lib/ ->" , try with removing the link by hand.

Small test code to regenerate the error fast:

import java.awt.print.PrinterJob;

class DummyPrinter {
   public static void main(String[] args) {
       try {
           PrinterJob printJob=PrinterJob.getPrinterJob();
       } catch( Exception e) {

SuSE 10.2 & Ubuntu Feisty: A missing file /etc/cups/client.conf might confuse java and java detects no printer. Create /etc/cups/client.conf with the content "ServerName localhost" in this case.

I get an error java.lang.NoClassDefFoundError or java.lang.NullPointerException when starting FreeMind

When trying to start FreeMind from a console, you get the following error messages and FreeMind doesn't start:

This is because you use kaffe (the same applies to libgcj, sablevm and a few others), which doesn't offer all features of Sun's Java. Blackdown's Java do es as well work, I would have doubts on any other implementation (beside perhaps IBM's one). So, remove this Java version and install a version from Sun or Blackdown.

if you've installed FreeMind from a package, you can alternatively use the solution under #How_can_I_make_FreeMind_use_a_specific_Java_Virtual_Machine.3F.

While installing a FreeMind package, it complains Java isn't installed, though I've installed it and Java programs do work

You've probably installed Java manually, and not from an RPM resp. DEB package. This means that the FreeMind RPM resp. DEB package can't know that Java is installed.

Three solutions (from better to worse):

  • Install Java from an RPM or DEB package and retry to install the FreeMind package.
  • Install FreeMind using the ZIP file.
  • Install the FreeMind package by ignoring the missing dependencies, e.g.:
   # rpm -Uvh -nodeps freemind....noarch.rpm

While installing a FreeMind RPM package, it complains Java isn't installed, though I've installed it from an RPM package

You've probably installed the JDK package from Sun, which provides also a JRE but doesn't say it. Your best chance is to install the dummy package j2sdk-provides-j2re-1.4.2-2.noarch.rpm. The source package is available as well.

How can I make FreeMind use a specific Java Virtual Machine?

If you've installed FreeMind from a package, you can make it use a different Java virtual machines than other programs by adding lines similar to the 2 following ones to /etc/freemind/freemindrc, for all users, or to $HOME/.freemind/freemindrc, for you, so that only FreeMind is impacted (and no other program):

   export PATH=/usr/java/j2re1.4.2_04/bin:$PATH
   export JAVA_HOME=/usr/java/j2re1.4.2_04

(the part in italic depends on your installation)

Why doesn't the rebuild of the SRPM work under Fedora Core 2

During rebuild of the RPM, lines similar to the following do appear and the build fails:

   [mkdir] Created dir: /usr/src/redhat/BUILD/freemind-0.7.1/bin/classes
   [javac] Compiling 92 source files to /usr/src/redhat/BUILD/freemind-0.7.1/bin/classes
   [javac] /usr/src/redhat/BUILD/freemind-0.7.1/freemind/freemind/modes/
                                                                    error: '{' expected.
   [javac]        };
   [javac]         ^
   [javac] /usr/src/redhat/BUILD/freemind-0.7.1/freemind/freemind/modes/
Public interface `freemind.modes.ID_Blank' must be defined in a file called `'.
   [javac]        public interface ID_Blank extends ID_BasicState {};
   [javac]                         ^

The ant package delivered with Fedora Core 2 seems to be broken (version is 1.5.2, but my ant version is 1.5.1 and it works). Installing ant (and dependencies) from the JPackage Project seems to solve the problem.

Under Fedora Core 3, Java complains in about missing

The exact error message is:

Exception in thread "main" java.lang.UnsatisfiedLinkError:
cannot open shared object file: No such file or directory

In this case install the package xorg-x11-deprecated-libs-6.8.1-12.i386.rpm, e.g. using yum, this should solve the problem.

FreeMind seems broken and I have the Gtk Look&Feel

We already had quite a lot of issues with the Gtk Look&Feel, sometimes in aspects nobody would have thought relevant to the Look&Feel (e.g. hangs on file system access). Hence we strongly recommend to change your Look&Feel to something else before even trying to pin down the issue.

You can change it in the menu Tools → Preferences... → Appareance → Look and Feel. Should the problem be such that you can't even start the preferences menu (or FreeMind as a whole), edit the file ~/.freemind/ to uncomment and modify the lookandfeel parameter, as in:

lookandfeel = metal

Instead of metal, other valid values are nothing (for no Look&Feel at all), default (the... default one), windows or motif; mainly a matter of taste.

if the modification of ~/.freemind/ doesn't seem to change anything, remove the lookandfeel parameter from the file ~/.freemind/

And, yes, we know, Gtk looks sooo much better! (but we don't really care)

When resizing the FreeMind window, the inner field doesn't resize properly (or other GUI strangeness)

If you're using a 3D desktop (like Compiz or Beryl), that's most probably the reason for your issue. We don't have a fix yet and we even don't know if it's a FreeMind, a Java or a Compiz/Beryl issue. Hints are welcome. (This also happens with ratpoison and awesome.)

Beryl, Kubuntu-Feisty, sun-java6-jre: problems with resizing? This works for me:
  1. open FreeMind on Beryl Window Manager
  2. set Kwin (KDE Window manager) as actual Window manager
  3. select back Beryl Window manager - resizing works now!

This problem can be circumvented at least partially by editing the $HOME/.freemind/

Set the appwindow_height and appwindow_width to as high values as possible, so that you don't have to resize at all. If all toolbar icons fit to the screen, you're on the clear :).

Another hint: setting the AWT_TOOLKIT=MToolkit environment variable seems to solve some of the problems. I had the problem that in compiz-fusion the freemind window appeared undecorated and was unmanageable (couldn't be moved, resized, etc.). Setting this environment variable before running freemind solves this problem. I found the solution here. **Addition: This fix (also) works for awesome 2.3, in both tiling and floating modes.

On Awesome (and probably other tiling window managers [6]) adding AWT_TOOLKIT=MToolkit can fix some of the UI issues, but at the cost of causing Freemind to semi-randomly stop responding to keyboard events, usually after interacting with a dialog. This appears to be a bug in the JRE that affects a variety of applications. If you run

 wmname LG3D

before launching, it solves both problems without the environmental variable (if it is set, be sure to unset it). I have the window manager run this on startup and it seems to make everything happy.


Most people seem to think that, because you're relatively knowledgeable, they can tell you that something doesn't work, and you will be able to find out the solution, just like this!

Well, that's not exactly like this: first, I need to understand what the problem exactly is, and then I can try to solve it, especially if I've already seen and solved the problem. Think about your mechanic at the garage, if you give him a call and tell him "my car doesn't start" or "something is wrong with my car", would you expect him to tell you right away "Oh, yes, that's the plugs!". Most probably, he will ask to come by. Well, that's exactly the same here, I can't ask you to come by, but if you want good help, you'll need to give good information.

It's easier than you might thought, just do the following steps, that should give us a good start:

  • start a console, e.g. use Alt+F2, and type xterm or konsole or rxvt.
  • in the console, type the following statements:

On an RPM based system:

       DEBUG=1 freemind
       (quit freemind)
       /usr/bin/java -version
       rpm -qa | grep -i j
       rpm -qa | grep freemind
       env | grep -i j

On a Debian based system

       DEBUG=1 freemind
       (quit freemind)
       /usr/bin/java -version
       dpkg -l \*j\*
       dpkg -l freemind\*
       env | grep -i j
You should see which java command is used, e.g. "/usr/bin/java", from the debug output of the freemind command.

The result should look somewhat like this (error messages are OK, I like error messages!):

alice@wonderland:~> DEBUG=1 freemind
DEBUG:   Freemind parameters are .
DEBUG:   Using $PATH to find java virtual machine.
DEBUG:   Using '/usr/bin/java' as java virtual machine...

  • open a new thread in the Help Forum of the FreeMind Project,
  • putting Linux in the subject helps spot the right messages,
  • select the commands and what they output,
  • and paste the stuff using the middle button of your mouse in the message body.
  • Explain also your problem of course.
  • Add the name and version of your distribution (SuSE 8.2 or whatever).
  • If the problem is not completely specific to FreeMind, does the problem appear as well with other Java applications (we suggest JEdit because it uses the same graphical system "Swing")?
  • That should be all.

Building the Debian Package of FreeMind

Regarding the package source code, the package is embedded in the Debian processes and especially Java Maintainers team [7]:

  • the package source code is available to everybody [8] and well tracked [9]
  • there is a team around it and not only a single person.
  • a newbie can get help and support from this same team
  • Ubuntu Java developers are also on the mailing list, hence (slightly) better chances to get it into Ubuntu.
