Hello,
I am very interested by pythonocc; I try to build it from time to
time, but it always takes me a long time to figure out how to do it
(and why it fails on my system), and I give up for a few months until
the next try. This time, I would like to fix the build system to save
time ;-)
Here is my last try, with commit 191a184 on Linux; there is a toplevel
CMakeLists.txt, so I guess that I can use CMake, great! I always
build in a subdirectory:
$ mkdir build
$ cd build
$ ccmake ..
Building pythonOCC 0.5
Check whether the system is 32 or 64 bit.
-- 64bit system detected
/usr/lib/libTKernel.so
-- OpenCASCADE include directory: /Library/OpenCASCADE/6.3.0/inc
-- OpenCASCADE shared libraries directory: /Library/OpenCASCADE/6.3.0/lib
-- Unix/Linux system detected
Err, why that? It seems to find /usr/lib/libTKernel.so, but decides
that it will need files under MacOSX location, bad idea. Patch 01
fixes MESSAGE commands to not mess up ccmake, and patch 02 detects OCE
first (of course I am biased, but it is obviously a better idea when
building with CMake)
I set CMAKE_BUILD_TYPE to Release, and change CMAKE_INSTALL_PREFIX to
install pythonocc in my home directory.

Okay, build/./src/wrapper/SWIG/linux_darwin does not exist, let us
create it (patch 03).

Indeed, those libraries are needed by WOK and DRAWEXE plugins, they
are surely not useful for ppythonocc, let us remove them (patch 04).

Okay, it seems to work, but it builds only a very small subset. How
to build everything?
