Salve. I'm trying to use boost.threads in my project, as they look like the cleanest cross-platform threading interface I've seen in a while, and I'm running into a wee problem convincing the libraries to build. My setup: Windows 2000 SP 4 Microsoft Visual C++ 7.1 (C:\Program Files\Microsoft Visual Studio .NET 2003\VC7\) MS SDK (U:\Program Files\Microsoft SDK) Boost 1.31.0 (C:\boost_1_31_0, installing to C:\boost) Cygwin is installed, but not present in PATH; I am not using cygwin to build this project, only to run PostgreSQL. Python is not installed, as I have no need for it. Visual C++ 6.0 is also installed (for legacy projects), but not present in PATH. bjam is present in PATH, as downloaded from Sourceforge. C:\boost_1_31_0> bjam -v Boost.Jam Version 3.1.9. OS=NT. Attempting to run bjam results in a lengthy list of errors: -- long paste -- C:\boost_1_31_0> bjam -sTOOLS=vc7.1 --------------------------------------------------------------------- skipping Boost.Python library build due to missing or incorrect configuration (...) --------------------------------------------------------------------- ...patience... ...found 5266 targets... ...updating 747 targets...

What is vc-C++ doing and where can I find it? There is no file with that string in the name anywhere in the boost tree. As far as I can tell, it fails to build any object files at all. Any suggestions? Owen
