Hi Frank,
There's not any Win64 specific code because I did not have the opportunity
to have a Win64 machine to test pythonocc with this platform. However I do
think that the 64bit code for linux/darwin could be used as is for Win64.
The script environment.py first detects whether or not python is 64 bit (by
querying sys.maxint). After that, according to the result (32 or 64bit),
environment.py decides to set -D_OCC64 as a compiler define. That's all. If
you just append ('_OCC64',None) to the DEFINE_MACROS list, you should have
pythonocc compiled properly under Win64.
Just a question: under Win32, sys.platform returns the 'win32' string. Is
'win64' returned under win64?
I will create a branch named tp/win64-support (don't know if you're familiar
with git). I will notify you when it's done so that you can test building
pythonocc from github (https://github.com/tpaviot/pythonocc). I don't know
if there are speficic things to be aware of when dealing with python and
windows in 64 bit mode, feel free to send any suggestion.
Best Regards,
Thomas
