[vtkusers] UnsatisfiedLinkError (Linux/Java)

[Prabhu Ramachandran]

hi,

	Try this.  In the file java/Makefile change the following lines

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}

to

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

The only difference being the -lXt added in the last line.

After this, remake vtk by running make on the base vtk source dir.  If 
this is a premade deb from SuSe, also file a bug. :)
