[Help-glpk] JNI

[Welson Sun]

Hi all,
 
I downloaded and installed the GLPK4.4 on Redhat 9. The stand alone slover
and the C API compiles OK and works fine. But I am having trouble making the
JNI work.
 
Under glpk-4.4/contrib/jni/, I typed "make all" and "make install", it
compiles OK and installed correctly.
 
But then I entered: glpk-4.4/contrib/jni/sample, and tried "make test", it
outputs:
 
java -Djava.library.path='../c' -classpath './:../java/glpk.jar'
GlpkMagicSquare

Sample: Can't instantiate solver:
Sample:  ** java.lang.UnsatisfiedLinkError:
/opt/j2sdk1.4.1_01/jre/lib/i386/libglpk_jni.so:
/opt/j2sdk1.4.1_01/jre/lib/i386/libglpk_jni.so: undefined symbol:
lpx_realloc_prob
Sample:  ** java.library.path: ../c
Sample: Probably you don't have GLPK JNI properly installed. 
 
 
If I use: java GlpkMagicSquare, it outputs:
 
Sample: Can't instantiate solver:
Sample:  ** java.lang.UnsatisfiedLinkError:
/opt/j2sdk1.4.1_01/jre/lib/i386/libglpk_jni.so:

What is the problem? Has anyone got the JNI working under Linux? And How?

Another problem is that I tried this package in Cygwin on Windows XP,  the
stand alone and C API looks great, I can run the stand alone and in
glpk-4.4/examples, the "make check" works fine. But when I tried to build
the JNI, it has a lot of errors:

make[1]: *** [glpk.o] Error 1

make: *** [libglpk_jni.so] Error 2 


In the README under glpk-4.4/contrib/jni directory, there is one setence:
Currently, Windows is not supported in the Makefiles.

What does this mean? Does this mean that the current JNI interface cannot
work under windows or only the Makefile does not support Windows? How can
modify it to support Windows?


Thanks a lot!



Yours,

Welson Sun
