Hey Jerome, > Matthijs I still trying to compil rc but I can't. the problem > is jam can't find parser.cpp and parser.cpp.h > > can you help me please. Like I said before, you need to re-compile Jam first. The source code is in /src/tools/jam. I _think_ you can type 'make' to compile Jam, but I am not sure. Unfortunately, I don't have a working BeOS right now, so I can't check what you need to do exactly. But you have to re-compile Jam. -Matthijs
