[vtkusers] Compiling VTK for 64-bit on Unix - Java wrappers

[Brian Hanna]

Hi all,

I'm a VTK and cmake novice. I'm compiling VTK 5.0.4 for 64-bit on RHEL 5 
using cmake 2.4.8. I have the 64-bit JDK installed and linked under 
/usr/java/latest. (cmake was compiled for 64 bit from source to solve 
another problem with TCL wrappers.)

I'd like the java wrappers for VTK. I ran into a small problem when linking:

[ 98%] Built target VTKJava
Linking CXX executable ../../bin/VTKJavaExecutable
/usr/bin/ld: warning: libmawt.so, needed by 
/usr/java/latest/jre/lib/amd64/libjawt.so, not found (try using -rpath 
or -rpath-link)
/usr/bin/ld: warning: libjvm.so, needed by 
/usr/java/latest/jre/lib/amd64/libjawt.so, not found (try using -rpath 
or -rpath-link)

The needed libraries are in /usr/java/latest/jre/lib/amd64, under the 
xawt and server subdirectories.

A vtkusers mailing list entry from 2005 [1] tells me to add these to 
LD_LIBRARY_PATH before make, and that works for me. But isn't there a 
place in ccmake where I can specify these libraries without resorting to 
LD_LIBRARY_PATH?

For libjvm.so, there appears to be a variable specifically for that: 
JAVA_JVM_LIBRARY. I set it to the correct path to the library, but I 
still got the link error.

For libmawt.so, there is a variable for awt library: JAVA_AWT_LIBRARY. I 
tried adding the additional library onto that, but it didn't work. 
Apparently that is only a single library, not a list.

Here's my ccmake variables:
>  JAVACOMMAND                      /usr/bin/java
>  JAVA_ARCHIVE                     /usr/bin/jar
>  JAVA_AWT_INCLUDE_PATH            /usr/java/latest/bin/../include
>  JAVA_AWT_LIBRARY                 
> /usr/java/latest/jre/lib/amd64/libjawt.so
>  JAVA_COMPILE                     /usr/bin/javac
>  JAVA_INCLUDE_PATH                /usr/java/latest/bin/../include
>  JAVA_INCLUDE_PATH2               /usr/java/latest/bin/../include/linux
>  JAVA_JVM_LIBRARY                 
> /usr/java/latest/jre/lib/amd64/server/libjvm.so
>  JAVA_RUNTIME                     /usr/java/latest/bin/java
What should I be using to get cmake to find xawt/libmawt.so and 
server/libjvm.so? Or is this a known problem?

Thanks,
