In order to properly run the tests, you <u>may</u> need to make a few changes. The '''PATH''' variable is reinitalized when the test cases are run. Normally, the tests ''will'' fail when they try the cl tests. This is because PATH does not look for the cl executable and the libraries. Tom and Cesar have made certain assemptions when extending the include path, and included these following paths :
/cygdrive/c/Program Files/Microsoft Visual Studio 8/VC/bin
/cygdrive/c/Program Files/Microsoft Visual Studio 8/Common7/IDE
If it is different for your machine, you need to find these in the Makefile.in or Makefile and change them to your settings.
