Hello, I use VS2003.Net to build pythonOCC and didn't try with VS8 or 9. It's an issue related to the build of python extension under Windows with VS>2005; I think this question should have widely already been discussed. Please et us know if you have any tip to solve the problem. If you want to build your own pythonOCC, you have to modify the line 27 of "Standard_Real.hxx" (in order to avoid the gccxml parsing error you mention): #if defined(WNT) && !defined(__SWIG_GENERATION__) && !defined(__CYGWIN32__) && !defined(__MINGW32__) Best regards, Thomas Paviot > On Sat, Oct 4, 2008 at 9:13 PM, Dave Cowden <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > Hi: > > Im hoping to use pythonOCC as a part of a project I'm working on > for the RepRap project.
