== Bugfix scons for 32bit building ==
Due to a bug, versions of scons '''<=2.3''' should alter a line in:<br>
'''C:\WinPython27\WinPython-32bit-xxx\python-xxx\Lib\site-packages\scons-2.3.0\SCons\Tool\MSCommon\vc.py'''
Line '''364''':
<source lang="python">
if not req_target_platform and target_platform in ('amd64','x86_64'):
try_target_archs.append('x86')
</source>
Should be:
<source lang="python">
#if not req_target_platform and target_platform in ('amd64','x86_64'):
# try_target_archs.append('x86')
if target_platform in ('amd64','x86_64'):
try_target_archs.append('x86')
print "requested", req_target_platform
print "target", target_platform
print "try", try_target_archs
</source>
If not fixing the bug, you will get:
<source lang="powershell">
