Hi again,

not exactly ... when I used the --with-java flag I had this problem with
the Makefile not finding dependent classes and so on (it was on the list
in May I think). I found a solution in the archive which worked: 
after configuring without java I put in the system.make:

BUILD_JAVA    = build_java
CLEAN_JAVA    = clean_java
 
then gmake. And everything worked fine.

My JAVA_CLASS_HOME is on vtk31/java, but this libvtkJava.so just isn't
there. Anyway - I should find it with the find command if it was there.


That's what I did:

-----

1. user.make

MESA_INCLUDE=-I/usr/include/GL
MESA_LIB=/usr/lib/libMesaGL.so

JDKHOME=/usr/local/jdk1.2.2
JAVAC=${JDKHOME}/bin/javac
JAVA_CLASS_HOME=/usrc2/image/faulhabe/vtk31/java
JAVAH=${JDKHOME}/bin/javah
JAVA_INCLUDES=-I${JDKHOME}/include -I${JDKHOME}/include/linux
JAVA_CXX_LIB=/usr/lib/libiberty.a
/usr/lib/gcc-lib/i486-suse-linux/2.95.2/libstdc++.a
/usr/lib/gcc-lib/i486-suse-linux/2.95.2/libgcc.a

2. classpath

export CLASSPATH='.:/usrc2/image/faulhabe/vtk31/java'

3. java/Makefile.in

libvtkJava$(SHLIB_SUFFIX):
        $(CXX) ${CXX_FLAGS} ${VTK_SHLIB_BUILD_FLAGS} \
        -o libvtkJava$(SHLIB_SUFFIX) -L. ${XLDFLAGS} ${LDLIBS} \
        ${XLIBS} -lXext ${X_PRE_LIBS} -lX11 ${X_EXTRA_LIBS}
${JAVA_CXX_LIB} \
        -lXt
(added -lXt)

4. configure

./configure --with-opengl --with-shared --with-contrib
(I tried it with mesa and changed that according to Prabhu Ramachandran
because of the error with "undefined symbol: OSMesaMakeCurrent"

5. system.make

BUILD_JAVA    = build_java
CLEAN_JAVA    = clean_java

6. gmake

7. Links

made links to all .so-files (according to the Linux-howto) in a new
directory

8. .bashrc

export LD_LIBRARY_PATH=/usrc2/image/faulhabe/vtk31/my_vtk_shared_libs
export CLASSPATH='.:/usrc2/image/faulhabe/vtk31/java/vtk'
