Hello Ricardo,
on a 64bit system you could install two different Java runtimes:
A 32bit runtime and a 64bit runtime.
A 64bit runtime can only load 64bit libraries.
A 32bit runtime can only load 32bit libraries.
Did you check the bitness of the GLPK library (glpk.dylib)?
The glpk_java.dylib will load glpk.dylib. The bitness must match.
Yes, they match.
wi-3-218:~ death$ lipo -info /usr/local/lib/libglpk.dylib
Non-fat file: /usr/local/lib/libglpk.dylib is architecture: x86_64
wi-3-218:~ death$ lipo -info Downloads/libglpk-java-1.0.19/swig/.libs/
libglpk_java.dylib
Non-fat file: Downloads/libglpk-java-1.0.19/swig/.libs/
libglpk_java.dylib is architecture: x86_64
And the same error arises with 'make check':
Exception in thread "main" java.lang.UnsatisfiedLinkError:
org.gnu.glpk.GLPKJNI.glp_term_hook(JJ)V
at org.gnu.glpk.GLPKJNI.glp_term_hook(Native Method)
I've tested compiling *without* -m64 flag both, glpk and libgplk-java,
and again I obtain from Java the 'match-o, wrong architecture' error
For the bitness of GCC. Compile the proposed code with -m64 and
check the output again.
It seems it compiles for x64:
wi-3-218:~ death$ gcc -m64 test.c -o test
wi-3-218:~ death$ ./test
Running in 64bit mode.
Quite odd, any further idea?
Regards,
Ricardo

Betreff: Re: [Help-glpk] GLPK-Java JNI in Mac OS X 10.5.8
Dear Xypron,
OK, I've executed again the original ./configure and the original
Makefile without modifying anything.
/configure CPPFLAGS=-I/System/Library/Frameworks/
JavaVM.framework/Headers SWIGFLAGS=-I/System/Library/
Frameworks/JavaVM.framework/Headers JAVA_HOME=/System/Library/
Frameworks/JavaVM.framework/Versions/1.6.0/Home/
I've properly set JAVA_HOME avoiding the 'invalid source release',
thank you. I don't get why MacOS have all JavaVM installed by default
up to 1.6, and the 'Current' is linked to 1.5 by default ¿? anyway...
Setting all by default, as I said, without modifying anything, this
is
the error I get when executing 'make check':
Exception in thread "main" java.lang.UnsatisfiedLinkError: /Users/
death/Downloads/libglpk-java-1.0.19/swig/.libs/libglpk_java.0.dylib:
no suitable image found. Did find: /Users/death/Downloads/libglpk-
java-1.0.19/swig/.libs/libglpk_java.0.dylib: mach-o, but wrong
architecture
I've been googling, and I found that it seems that Java is not able
to
load a 32bit library, even it should be:
$ lipo -info /usr/bin/java
Architectures in the fat file: /usr/bin/java are: ppc7400 i386 x86_64
And the GLPK-java library is:
$ lipo -info libglpk-java-1.0.19/swig/.libs/libglpk_java.dylib
Non-fat file: libglpk-java-1.0.19/swig/.libs/libglpk_java.dylib is
architecture: i386
That's the reason I added the flag -m64. By compiling it with such a
flag, I get the error I commented before:
Exception in thread "main" java.lang.UnsatisfiedLinkError:
org.gnu.glpk.GLPKJNI.glp_term_hook(JJ)V
at org.gnu.glpk.GLPKJNI.glp_term_hook(Native Method)
About the architecture, I think (please correct me if I'm wrong) that
MacOS X 10.5.8 is 32bit kernel only.
I've checked with the source codes you've given to me and the results
are:
GCC: Running in 32bit mode.
Java: 64
So... I'm running a JavaVM 64bits in a computer running in 32bit
environment... interesting
Any further idea?
Best regards,
Ricardo
