How do I build and install P4Python for Mac OS X?

Question

I've been unable to build P4Python for an Intel Mac OS X 10.5.5.

These are my steps:

1. I downloaded p4python.tgz (from http://filehost.perforce.com/perforce/r07.3/tools/) and expanded it into "P4Python-2007.3".
2. I downloaded p4api.tar (from http://filehost.perforce.com/perforce/r07.3/bin.macosx104x86/) and expanded it into "p4api-2007.3.143793".
3. I placed "p4api-2007.3.143793" into "P4Python-2007.3" and edited setup.cfg to set "p4_api=./p4api-2007.3.143793".

4. I added the line 'extra_link_args = ["-framework", "Carbon"]' to setup.py after:

   elif unameOut[0] == "Darwin":
       unix = "MACOSX"
       release = "104"
       platform = self.architecture(unameOut[4])
   

5. I ran python setup.py build and got:

$ python setup.py build

which gcc returns /usr/bin/gcc and gcc -v returns:

python -V returns Python 2.4.3.

Answer 1

From http://bugs.mymediasystem.org/?do=details&task_id=676 suggests that Py_ssize_t was added in python 2.5, so it won't work (without some modifications) with python 2.4.

Either install/compile your own copy of python 2.5/2.6, or work out how to change P4Python, or look for an alternative python-perforce library.

Answer 2

Very outdated, but maybe you can use http://public.perforce.com:8080/@md=d&cd=//guest/miki_tebeka/p4py/&c=5Fm@//guest/miki_tebeka/p4py/main/?ac=83 for now

Answer 3

The newer version 2008.1 will build with Python 2.4.

I had posted the minor changes required to do that on my P4Python page, but they were rolled in to the official version.
