regex build problem

Hi everybody I tried to build boost out of the box. Everthing worked fine except the following: ------------------------------------- D:\boost\boost_1_30_0>bjam "-sTOOLS=cwpro8" ... FileClone libs\regex\build\bin-stage\boost_regex_debug.lib The system cannot find the file specified. ... FileClone libs\regex\build\bin-stage\boost_regex.lib The system cannot find the file specified. -------------------------------------- The actual file names generated in libs\regex\build\bin-stage are: libboost_regex_debug.lib and libboost_regex.lib, i.e. they have an extra "lib" prepended. Interestingly enough the analogous dll files are: boost_regex_debug.dll and boost_regex.dll as expected. Any ideas? Benedikt
