Hi, using Code Blocks i got the folowing message.ld.exe "Cannot find -lboost_filesystem-mgw-mt-s-l_33_l"So I decided to use bjam. Then, cd /jam source location/build.bat. Then I set the variables BOOST_ROOT= C:\Documents and Settings\src\boostand BOOST_BUILD_PATH=C:\Documents and Settings\src\boost\tools\build\v2. So what must I do now in order to build my project with bjam under Code Blocks? Be very clear, Thank You.
