Hi Thomas,
I meant one issue with linking Sketcher.i (I did geom project). There were
some warnings with swig not being able to treat overloading.
My cmake fix is not really a proper fix but rather a simple way to make it
work. The problem was with
INSTALL(FILES ${CMAKE_BINARY_DIR}/${LIBRARY_OUTPUT_PATH}/${OCE_MODULE}.py
DESTINATION ${${PROJECT_NAME}_INSTALL_DIRECTORY} )INSTALL(FILES
${CMAKE_BINARY_DIR}/${LIBRARY_OUTPUT_PATH}/_${OCE_MODULE}.${EXTENSION}
DESTINATION ${${PROJECT_NAME}_INSTALL_DIRECTORY} )
which I changed into
INSTALL(FILES ${LIBRARY_OUTPUT_PATH}${OCE_MODULE}.py DESTINATION
${${PROJECT_NAME}_INSTALL_DIRECTORY} )INSTALL(FILES
${LIBRARY_OUTPUT_PATH}Release/_${OCE_MODULE}.${EXTENSION} DESTINATION
${${PROJECT_NAME}_INSTALL_DIRECTORY} )
and did the same change at other places where it was doing the same thing.
Now, I don't know if something was wrong with my paths, but I had to change
these lines since it was obvious that cmake was looking at a wrong place.
With regards to display error which is the most serious since I cannot run my
programs from 32 bit windows, I realized that graphic module was using wx (my
version wxPython2.8-win64-unicode-py26 on python 2.6.5), but qt is possible.
So, I installed pyQt4 and forced backhand in SimplyGUI.py to USED_BACKEND ='qt'
and the display showed up. But only a couple of surface selections worked,
others selections were crashing the application. So, at least graphics works,
but something may be wrong with my installation since my unitest doesn't
succeed.

Subject: Re: [Pythonocc-users] pythonOCC on Windows 7 issues
2013/4/2 Vin Yovanovich <[email protected]>
I installed pythonOCC from master (3/28/2013) using a OCE 0.12 which I compiled
from sources.
Hi Vin,
Thank you for this report.
There were some issues with linking at one project so I had to comment in
Sketcher.i code
With "some issues", do you mean many or only one?
/*%nodefaultctor Sketcher_GUI;...
%extend Sketcher_GUI { void _kill_pointed() {
delete $self; }};*/
Interesting, I recently compiled latest pythonocc master on Win7 but did not
compiled geom. I have to check this out.
And also I had to fix main cmake file as it was not pointing at the right
source location from which it is supposed to install into OCC folder.
Can you post your fix here?
Issuing python test_all.py goes up to test_through_sections
(topology_building_unittest.TestTopologyBuilding) ... Test: through
sectionsthen Python crashes.
Strange, on my windows machine, all unittest runs fine.
However, what is more disturbing is that running python geometry_demos.py
gives

OpenGl_Window::CreateWindow: SetPixelFormat failed. Error code: 2000
Is this some kind of incompatibility with Windows 7?
This one is a real issue. I have 2 Win7 machines: one installed on a Acer
netbook, and a VirtualBox VM running on OSX. The same pythonocc binary fails on
the Acer machine (with the SetPixelFormat error you report), and works on the
VM. I have the feeling that this has something to do with OpenGl, but I can't
figure out what's wrong. Maybe the way pythonocc initializes the graphic
driver/window has to be fixed.
