nmake won't work in vs2008

Can somebody help me with this problem?

C:\Python25\source\tcl8.4.12\win>nmake -f makefile.vc

Microsoft (R) Program Maintenance Utility Version 9.00.21022.08

makefile.vc(22) : fatal error U1050:
You need to run vcvars32.bat from Developer Studio or setenv.bat from the
Platform SDK first to setup the environment. Jump to this line to read
the build instructions.
Stop.

yes, i'm running the command prompt from vs -> tools -> Visual Studio 2008 Command Prompt.

Perhaps you can find which part of the makefile produces that output, and check what environment variable it is looking for, and then set that environment variable to something sensible.

Thanks, I had somehow assumed that error was being generated by nmake.exe. d'oh!
