Hi,
the error "java.lang.NoClassDefFoundError: org/herac/tuxguitar/gui/TGMain", is saying the TGMain class of tuxguitar didn't found.
so there is a CLASSPATH problem.
As you installed "tuxguitar-1.0-linux-x86-installer.bin"
and you exec "tuxguitar" without set a path, i think you made a symbolic link on /usr/bin (or /usr/local/bin, etc )
That launcher script of that package was maded thinking on allow to move the folder where you want,
so the first what "where_is_tuxguitar/tuxguitar" script do, is check the current directory, and set relative paths.
e.g: tuxguitar.jar is setted as
current_dir/tuxguitar.jar
As you run it on a symbolic link, the current_dir is taked as /usr/bin, so /usr/bin/tuxguitar.jar don't exists.
If you want to add tuxguitar on /usr/bin, i suggest you make a new "script" instead of a symbolic link.
so the new script can be as:
-----------------------------
#!/bin/sh
/where_is_tuxguitar/tuxguitar
-----------------------------
then i think that script will work without problems.
