[Help-glpk] Problems using glpk from Java

[Alberto Marin]

Hello everybody,

I am using GLPK from java and I am having a few problems. I am trying to use the version that comes by default in Ubuntu but the same problems arise with other versions.

I have the jar file, the glpk_java library and libglpk.so library in a directory where all my dependencies are. The classloader finds the jar file and libglpk_java, but it fails to find the libglpk.so that is sitting in the same directory. 

the error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/amarin/NetBeansProjects/latest/CaMBio/lib64/Linux/libglpk_java.so.0.31.0: libglpk.so.0: cannot open shared object file: No such file or directory
    at java.lang.ClassLoader$NativeLibrary.load(Native Method)

Could not find the main class: de.mpg.biochem.cambio.tests.testglpk. Program will exit.
Java Result: 1

This file can only be found if I place it in /usr/lib and nowhere else but I need it in my dependencies dir. (This all becomes even worse if I call glpk from the Netbeans platform...)

 Is it the way the library is packed? I am doing something wrong?

Any help would be appreciated

Thanks,
Alberto
