I've been making an attempt to build the pythonocc bindings myself, and i
could use some help.
So far, I got py++, got gcc-xml installed ( had to build it from source
since i have vs 2008 express edition ), and downloaded and installed swig.
For VS9, i had to change a couple of the declarations of some constants from
Standard_Real, which were throwing "invalid use of extern".
I updated my environment.py to point to the opencascade libs, which i
downloaded and installed.
I downloaded the python scripts from SVN, and successfully ( I think )
generated the files in SWIG_src by running python setup.py install
but i'm getting error about not having visual studio 2003 installed :
Session
Vars
running install
running build
running build_ext
error: Python was built with Visual Studio 2003;
extensions must be built with a compiler than can generate compatible
binaries.
Visual Studio 2003 was not found on this system. If you have Cygwin
installed,
you can try compiling with MingW32, by passing "-c mingw32" to setup.py.
I feel like i'm on a very long journey here. Can anyone provide me some
tips on what combination of stuff I need installed to get this going?
thanks!
