Re: [fedora-java] Linking to libjava.so

I'm trying to package up a java package for octave that links to

module at run time it can't find libjava.so. How should this be remedied?
__java__.oct requires JNI_CreateJavaVM which is defined in libjvm.so. libjvm.so
is designed to be dlopened, rather than linked-to directly and loaded from
LD_LIBRARY_PATH. So in __java__.cc:initialize_jvm, modify the Unix branch of
the __WIN32__ ifdef to dlopen /usr/lib/jvm/jre/lib/$arch/client/libjvm.so and
locate JNI_CreateJavaVM using dlsym. You can probably re-use the octave_shlib
code from the win32 branch after jvm_lib_path initialization. $arch can be
discovered and substituted by configure.
