[Boost-users] [Boost.Filesystem] problem to link an executable to boost_filesys tem static library on Windows XP

Hello, I try to build an console executable that uses boost_fileystem library. I have got the file boost_filesystem-vc71-mt-1_33.lib. My IDE is Visual C++ 7.1. I set the preprocessor definition _MT. At build step, I have this error: "could not find boost_filesystem-vc71-mt-s-1_33.lib". I had a look to boost/config/auto_link.hpp to see what "#define" I forgot but I do not understand why it chooses "#define BOOST_LIB_RT_OPT -s". hat preprocessor macro should I define to make it choose "#define BOOST_LIB_RT_OPT" (i.e. empty) ? Is there a blocking problem with Visual C++ 7.1 on Windows XP ? Thank you. Johan GUIHENEUF
