Undefined symbol: _ZTI5TPave


I try to use RootHealPix
After some small correction I am able to compile it
But then using it:

libRootHealPix is missing a symbol _ZTI5TPave. You’re probably not linking that library against libGraf.so - and you should because it needs it. ldd libRootHealPix.so should show libGraf.so and I bet it doesn’t.

Cheers, Axel.
