HI, Anyone has compiled boost library successfully using dev-cpp the new version. I try compiling it and it gives many errors. I follow the following qway to compile: C:\projects\boost> C:\projects\boost>set path=c:\dev-cpp\bin C:\projects\boost>set MINGW_ROOT_DIRECTORY=c:\dev-cpp C:\projects\boost>set MINGW_BIN_DIRECTORY=c:\dev-cpp\bin C:\projects\boost>set MINGW_INCLUDE_DIRECTORY=c:\dev-cpp\include C:\projects\boost>set MINGW_STDLIB_DIRECTORY=c:\dev-cpp\lib C:\projects\boost>bjam -sTOOLS=mingw I tried many different option including usig MSYS with no luck. Thanks with best regards, Vikrant
