[p4python] P4Python build on Mac Os 10.5 Intel - SOLVED

Hi all,

        I figured I'd pass along how I was able to compile the latest 
p4api (p4api-2007.3.143793) with the Perforce supported p4python 
(P4Python-2007.3) on Mac OSX 10.5 Intel hardware.  This should work with 
PPC too but a minor tweak (arch) will need to be done.

So basically here is the problem with compiling on mac OS X.  By default 
python wants to compile universal binaries. I got an email from support 
that warned me this would be a problem. 
Since I'm not too familiar with the inners of compiling c (interaction 
with setup.py) from within python this hack fixes it so P4Python will 
compile and work.

Normally if you left it alone and ran setup.py you would see the following 
errors upon trying to import P4..
    Traceback (most recent call last):
      File "p4test.py", line 6, in <module>
        import P4
      File "build/lib.macosx-10.5-i386-2.5/P4.py", line 185, in <module>
        import P4API
    ImportError: dlopen(build/lib.macosx-10.5-i386-2.5/P4API.so, 2): 
Symbol not found: ___CFConstantStringClassReference
      Referenced from: 
      Expected in: dynamic lookup 

Corrections made - see the script..

As you can see arch has been reduced to only look at intel and we removed 
-Wstrict-prototypes as this isn't used for C++

When you get down to the linking stage things changed.  In addition to 
removing the universal capability we also 
had to put in the Carbon frameworks.

This script will replace 'python setup.py build'.  I would suggest the 
following process to get P4Python working:
Get the API Tree and P4Perforce untar / gunzip and put the api tree into 
P4Python-2007.3 directory
http://filehost.perforce.com/perforce/r07.3/bin.macosx104x86/p4api.tar -o 
   curl http://filehost.perforce.com/perforce/r07.3/tools/p4python.tgz -o 
Update the setup.cfg to point the p4_api=./p4api-2007.3.143793
Run a baseline 'python setup.py build'  - This will create all of the 
necessary trees.
Place this script in the P4Python directory.  Then run this script 
Run the install piece 'python setup.py install'

Note The testharness breaks but that's primarily due to a poor testharness

Sven Erik,

Did you see my description of my problem in 
http://maillist.perforce.com/pipermail/p4python/2008-April/000052.html? As 
I wrote in the thread, I contacted Perforce tech support and was told that 
Mac OS X is not supported.  But I thought that since you wrote the above, 
you may be able to diagnose my problem.
