I am trying to compile a python extension that uses
Quicktime Video Output Components
as shown in the Mac Developers Library
SimpleVideoOutXcode.xodeproj
i am building the extension using the setup.py script attached below
I need to run python in 32-bit because Quicktime has not been upgraded to 64-bit
I am running 10.7.2 and the Apple installed python 2.7.1
/usr/bin/python: Mach-O universal binary with 2 architectures
/usr/bin/python (for architecture x86_64): Mach-O 64-bit executable x86_64
/usr/bin/python (for architecture i386): Mach-O executable i386
this is an excerpt of the output i am getting when I try to build the extension
NOTE: this line
KVoutModule.c:44: error: expected specifier-qualifier-list before
‘QTVideoOutputComponent’
seems to indicate that I am not including the Quicktime/QuicktimeComponents.h
header (which I am)
as shown in the excerpt from the KVout.c source.
relavent setup.py line:
include_dirs = ['.', '/System/Library/Frameworks/Quicktime.framework/Headers/']

QUESTION:
Is there something more I need to do (or am I doing something wrong) that is
keeping this from compiling
