You're right, there maybe a #define SWIG 1 somewhere or something like
that. Which SWIG version do you use?

Hi Thomas
It looks like the "SWIG" string in Visualization.i is replaced by
"1", because if I change the path to something else, and copy
ExceptionCatcher.i there, it works - possibly a macro substitution
type of thing?

Hi Thomas
I made some progress on this in the last hour or so:
1. sys.platform is still "win32", even for 64 bit Python.
Funny!
2. The sys.maxint check does not work on Windows - it returns
the 32 bit max, even though I am definitely using Python 2.6
64bit.
I didn't know about that. I thought the maxint was 2^63-1 when
python is compiled in 64bit mode.
I have found other references to this on some messageboards.
The suggested way to work around this is to check the 1st
value returned by "platform.architecture()", which returns
('64bit', 'WindowsPE').
Very interesting, I will move to this function. I tested that it
returns '32bit' for OSX/python2.5 and '64bit' for OSX/python2.6.
Thanks.
3. To link with the 64bit versions of the OCC libs, I made
this change:
if sys.platform=='win32':
OCC_LIB = os.path.join(OCC_ROOT,'win%d'%bits,'lib')
Ok. This has to be properly handled.
4. I added the 64 bit flags, as you also suggested in your email:
if bits==64:
DEFINE_MACROS.append(('_OCC64',None))
SWIG_OPTS.append('-D_OCC64')
However, I currently get this error:
C:\Python\pythonocc-0.5\src\wrapper\Visualization\Visualization.i(25)
: Error: Unable to find '..\1\ExceptionCatcher.i'
error: command 'swig.exe' failed with exit status 1
Strange, line 25 of Visualization.i should be:
%include ../SWIG/ExceptionCatcher.i
Any idea where this could stem from?
Absolutely not. What about the other modules?

I am wondering if anyone has tried to build pythonocc
for 64bit Python on Win64? Looking at environment.py.
there is no special case code for 64 bit builds on
Windows yet, although there is for Linux and MacOS.

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
