Hello, i recently upgraded from msvc 8 to 9. Now I have to rebuild all my libraries, including boost. To do so, I am executing bjam --without-mpi --without-python --toolset=msvc-9.0_64 address-model=64 install bjam --without-mpi --without-python --toolset=msvc-9.0_64 address-model=64 clean in the Visual Studio x64 build command promt.

How can I fix this error? -Christoph I am using Windows Vista x64 and --------------------------------- Ihr erstes Fernweh? Wo gibt es den schönsten Strand.
