Hi, when I use bjam -sTOOLS=vc-7_1 "-sBUILD=debug <debug-store>database" lib I get LNK4044 linker warning because the /PDB command line switch is not supported (but ignored) for archive targets. I suppose the vc-Archive action in msvc-tools.jam shouldn't use PDB_LINKFLAG because I can't see why it should be needed. cheers, aa -- Andreas Ames | Programmer | Comergo GmbH | Voice: +49 69 7505 3213 | andreas . ames AT comergo . com
