I currently work on a scons based build process that will be fairly more portable, simple and reliable. It's almost done but still experimental and need testing. To test it:
$ cd pythonocc $ svn update $ cd src $ scons > I think the utils directory is missing from the .tar.gz - try using the > svn checkout instead. > > I also notice in your error listing that CAS_ROOT isn't set.

Under Windows, OpenCascade installation is quite simple: includes are in CASROOT/inc and libraries in CASROOT/lib. Under Linux, it depends on your distribution, and OpenCascade files maybe anywhere (/opt, /usr/local/inc, /usr/inc et.). That's why it's so difficult to automate the compilation process and why it's necessary to hack the environment.py script. > Good luck! > > Arthur > Best Regards, Thomas > > ben lipkowitz wrote: > >> Congratulations on your first release.
