Hi,
I had the same kind of problems. Apparently, one needs to generate TWO
libraries for each one that was generated before. One for the symbols,
one for the code.
Can someone explain a little better why and how to do it properly ?
I'm also still stuck to that kind of problems. ROOT works fine (so the
problem seems solved for it) but my code doesn't work, while it does on
all other platforms.
Cheers
Damir
