[Boost-users] Problem for compiling Boost 1.53

Hi, When I try to compile boost with this command line : .\b2 toolset=gcc -j4 --build-type=complete --without-mpi --prefix=C:\librairies\boost-1.53.0 --user-config=user-config.jam install I have the error that you can see in the out.txt file in attachment and the user-config.jam file in attachment either. I try to compile Boost in MinGW with GCC 4.7.2. Someone can help me :-) Thanks in advance. Best regards. Julien.
