Some time ago my bjam/comeau set up ceased to function. I get messages like: C++ prelinker: executing: c:\Program Files\como433\bin\como --vc71 -e5 --no_vers ion --no_prelink_verbose --display_error_number --long_long --diag_suppress= 9,21 ,161,748,940,962 -D__STL_LONG_LONG -DNDEBUG -DNDEBUG -DBOOST_LIB_DIAGNOSTIC= 1 -- a -DBOOST_COMO_STRICT=1 --inlining -D_WIN32 -DBOOST_SP_DISABLE_THREADS --exc epti ons -DBOOST_DISABLE_WIN32 --wchar_t -I..\..\..\bin\boost\libs\serialization\ buil d -Ic:\Program Files\como433\libcomo c:\Program Files\como433\libcomo\cnames -IC :\BoostMainCVS -IC:\BoostMainCVS -IC:\BoostMainCVS -o ..\..\..\bin\boost\libs\se rialization\build\libboost_serialization.lib\como-4_3_3-vc7_1\release\binary _oar chive.obj -c ../src/binary_oarchive.cpp 'c:\Program' is not recognized as an internal or external command, operable program or batch file. My como path variable is set: COMO_PATH="c:\\Program Files\\como433" I also tried COMO_PATH="c:/Program Files/como433" but it made no differenc I didn't change anything as far as I know. Does anyone have any suggestions? Robert Ramey
