[vtkusers] undefined reference to `JAWT_GetAWT

[Neil Killeen]

Bernard

thanks for that advice; I took it !

In the end, all I had to do was add

/usr/local/java/jdk1.5.0_10-ia64/jre/lib/ia64
/usr/local/java/jdk1.5.0_10-ia64/jre/lib/ia64/rockit
/usr/local/java/jdk1.5.0_10-ia64/jre/lib/ia64/xawt

to LD_LIBRARY_PATH

and explicitly include

-ljawt


in the linker command.     Perhaps a VTK person could say why -ljawt  
was not automatically
in the list of libraries to link with ?


regards
Neil
