Hi...
So, I have this application called Impact, it is an explicit time integration Finite Elements code written in Java...
http://impact.sourceforge.net/
I untar the pack, and launch the application calling a script, from within the untarred folder,
Code:
alex@iskandhar:~/stuff/Impact$ ls
COPYING ImpactClusterServerKill.bat ImpactGUI_JOGL_OGL_solaris_sparcv9.sh ImpactGUI_OGL_windows_amd64.bat Pro.conf featured.ico

alex@iskandhar:~/stuff/Impact$./ImpactGUI_OGL_linux_amd64.sh
This launches a gui which allows me to setup a case, which needs some setup file, tipically some *.in and a mesh file, tipically some *.msh.
Other mode of executuion consists of calling the setup file as argument to Impact.sh script ( CLI execution mode, for g33k5
)
My problem is : I have packed the whole stuff into a Slackware .tgz, that places it in /usr/local/Impact, and placed a calling script in /usr/local/bin ,
Code:
alex@iskandhar:~/stuff/Impact/build# echo '/usr/local/Impact/ImpactGUI_OGL_linux_amd64.sh' > /usr/local/bin/Impact&&chmod +x /usr/local/bin/Impact
Why the heck doesn't it find the java libraries even after i having created the package with makepkg -l y -c n /path/to/package.tgz...?

I decided to hack the ImpactGUI_OGL_linux_amd64.sh script from
Code:
alex@iskandhar:~$ cat /usr/local/Impact/ImpactGUI_OGL_linux_amd64.sh
#!/bin/sh
export LD_LIBRARY_PATH=lib_j3d/linux_amd64
java -Xmx1000m -Xss1m -cp .:bin:doc:lib/jogl.jar:lib/gluegen-rt.jar:lib/patbinfree153.jar:lib_j3d/j3dcore.jar:lib_j3d/j3dutils.jar:lib_j3d/vecmath.jar -Djava.library.path="lib_j3d/linux_amd64" gui.ImpactGUI
to
Code:
alex@iskandhar:~$ cat /usr/local/Impact/ImpactGUI_OGL_linux_amd64.sh

no avail,

even after adding /usr/local/Impact/bin to PATH... won't go...
Can someone please tell me what is wrong here...?
I can run this thing from within its directory... but I do not like messing within the directories of my applications, this is why I sent this to /usr/local, and placed a calling script in /usr/local/bin...
Why can't this go...?
