[vtkusers] Problems in VTK Java & Linux

[Dhanesh Ramachandram, PhD]

Hi again Denis,

Actually I solved this issue by explicitly setting the environment
variable LD_LIBRARY within the Eclipse IDE.
However, I had earlier deleted by VTKBuild folder and re-configured
CMake. Somehow at 100% I get this following error:

[100%] Built target VTKJava
Linking CXX executable ../../bin/VTKJavaExecutable
../../bin/libvtkRenderingJava.so.5.5.0: undefined reference to `JAWT_GetAWT'
collect2: ld returned 1 exit status
make[2]: *** [bin/VTKJavaExecutable] Error 1
make[1]: *** [Wrapping/Java/CMakeFiles/VTKJavaExecutable.dir/all] Error 2
make: *** [all] Error 2


I tried Googling but cannot get a reliable solution.
