RE: [Help-glpk] JNI

[Welson Sun]

Hi, two questions.
(1)
I still cannot get the JNI work in Linux, that's really strange! ( Redhat 9
), here is what I did:

1 ./configure
2 make
3 make install
4 make check
5 cd contrib/jni
6 make all
7 make install
( NO PROBLEM TILL NOW)

8 make test ( ERROR, OUTPUT IS: )

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_1/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. 

A little bit strange here is that my JAVA_HOME is set to /usr/local/java,
but here it looks like: /opt/j2sdk1.4.1_01

Anybody has any clue where is wrong?

(2)
Under Windws XP, Cygwin
1 ./configure
2 make
3 make install
4 make check
5 cd contrib/jni
( NO PROBLEM TILL NOW)

6 make all
(TONS OF ERROR OCCURED,  SEE ATTACHED FILE)
Looks like it cannot compile $JAVA_HOME/include/jni.h and
$JAVA_HOME/include/win32/jni_md.h:
c:/j2sdk1.4.1_02/include/jni.h:108: error: syntax error before "jlong"
c:/j2sdk1.4.1_02/include/win32/jni_md.h:16: error: syntax error before
"jlong"

Should this be a gcc error?

But I got a work around: I download the compiled version from:
http://gottfried.lindner.bei.t-online.de/glpkJavaBsp.htm and put the jar
file into my CLASSPATH and add the path to the dll file, and that's all.
Both the example in this zip file and also the GlpkMagicSquare.java in
GLPK4.4 release work well.

Any idea on why this cannot be compiled under WIN32?

Hi Welson,

Two things that are a must in general
for any JNI to be installed:

* .jar file should get to directory where
  all other .jar filrs are
  (usually $JAVE_HOME/jre/lib/ext)
* native lib (.so) file should get where
  JVM is looking for them
  (usually $JAVA_HOME/jre/lib/i386)

I believe if you make sure both these files compiled by you are there it
should work.

Yes JNI works on Linux.

Regards,
Yuri
