Hi,
I running Debian unstable and have the official Debian package installed.
First I had problems with it, but after the update-alternative trick :
http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg388635.html Tuxguitar 0.9.1 runs well, but with no .gtp support.
I've read, that the CVS version can handles .gtp files, so I tried to build the CVS Version with this howto:
http://www.tuxguitar.com.ar/forum_posts.html?fid=5&tid=223&view=NEW
After editing the build.properties with the new path for swt:
lib.swt.jni=/usr/lib/jni
lib.swt.jar=/etc/alternatives/swt.jar
everything seemes to be fine, I get this messages, when finishing the build with ant:
Stoneface@neotux:~/TuxGuitar/TuxGuitar-cvs-src$ ant
Buildfile: build.xml
init:
build:
[echo] +--------------------------------------------------------------------+

[jar] Building jar: /home/Stoneface/TuxGuitar/TuxGuitar-cvs-src/tuxguitar.jar
package:

BUILD SUCCESSFUL
Total time: 6 seconds
But when I try to launch tuxguitar, the splash screen appears but tuxguitar crashes immediately and in the console I get this Java messages:
Stoneface@neotux:~/TuxGuitar/TuxGuitar-cvs-src$ ./tuxguitar

Hi,
there are 2 errors here..
the first "java.net.MalformedURLException: no protocol:...."
is caused because a conflict with the old ( 0.9 ) config..
remove ~/.tuxguitar/ to fix it.. ( but that's not the crash cause ).
the second.. "Exception in thread "main" org.eclipse.swt.SWTException: Unable to load graphics library [Cairo is required]...."
is the crash problem.
"libcairo2" is required.. do you have installed it ??
what version of swt do you have installed ???

Hi,
thanks Julian, with your help I've found the problem...
what version of swt do you have installed ???
I searched for the swt version and noticed, that my swt installation had some dependency problems...
I installed libswt3.2-gtk-java and libswt3.2-gtk-jni one more time and now tuxguitar starts correctly...
Great, thank you !
