Hi Chris, Thank you for your help.

...

The command I used was:

bjam --build-dir=C:\tmp\build-boost --toolset=msvc address-model=64 stage

Hi, you have to use the 'Visual Studio x64 Win64 Command Prompt', so the correct environment variables are set and then use bjam like:

bjam --build-dir=C:\tmp\build-boost --toolset=msvc-8-0_64 stage

I could compile with the toolset "msvc-8.0_64", I didn't know its existence. bjam --build-dir=C:\tmp\build-boost --toolset=msvc-8.0_64 stage Thanks, Yutaka.
