I'm trying to build the bjam executable by running build.bat from the boost/tools/build/jam_src directory. Here's what I get: C:\BOOST\TOOLS\BUILD\JAM_SRC>build.bat vc7 ### ### "Unknown toolset: vc7" ### ### You can specify the toolset as the argument, i.e.: ### .\build.bat msvc ### ### Toolsets supported by this script are: borland, como, gcc, gcc-nocygwin, intel-win32, metrowerks, mingw, msvc, vc7 ### I also tried running vcvars32 prior to build.bat and got this: C:\BOOST\TOOLS\BUILD\JAM_SRC>"e:\program files\microsoft visual studio .net\vc7\bin\vcvars32" C:\BOOST\TOOLS\BUILD\JAM_SRC>"E:\Program Files\Microsoft Visual Studio .NET\Common7\Tools\"vsvars32.bat Setting environment for using Microsoft Visual Studio .NET tools. (If you also have Visual C++ 6.0 installed and wish to use its tools from the command line, run vcvars32.bat for Visual C++ 6.0.) C:\BOOST\TOOLS\BUILD\JAM_SRC>build.bat vc7 Setting environment for using Microsoft Visual Studio .NET tools. (If you also have Visual C++ 6.0 installed and wish to use its tools from the command line, run vcvars32.bat for Visual C++ 6.0.) The system is Windows NT 4.0 SP6. I'm using a fresh cvs checkout of the entire boost source tree. I'd appreciate any help I can get with this. Thx, Bart
