And what might that symbol (or some of those symbols) be? That info
would help diagnose the problem.
I've successfully built native components using the C++ STL and
templated classes, so there doesn't seem to be a generic template
problem here. My steps were:
g++ -D_REENTRANT -fpic -c ...flags and files...
g++ -shared -o lib...
and I'm using the g++ environment shipped with RH6.0.
