pyrex hardcodes MACOSX_DEPLOYMENT_TARGET to 10.3

[harry@…]

In Mac/DarwinSystem.py there's a line that does this:

os.environ["MACOSX_DEPLOYMENT_TARGET"] = "10.3"

Which cases builds on Leopard to fail like this:

distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET mismatch: now "10.3" but "10.5" during configure

I maintain the py25-pyrex port and that builds fine for me on Leopard. Can you attach the complete build log i.e.:

$ sudo port -d install py-pyrex &> py-pyrex.log 

[harry@…]

Oops, I meant to say that other ports using pyrex fail to build. I'm trying to install py-glewpy, which has a dependency on python2.4. The error is:

Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_python_py-glewpy/work/glewpy-0.7.4" && /opt/local/bin/python2.4 setup.py build " returned error 1

IIRC the import of pyrex sets MACOSX_DEPLOYMENT_TARGET to 10.3 regardless of the actual OS version.

It does although it appears that theres something deeper going on here. I changed line 22 of ${prefix}/lib/python2.4/site-packages/Pyrex/Mac/DarwinSystem.py to set the deployment target to 10.5, i.e.:

os.environ["MACOSX_DEPLOYMENT_TARGET"] = "10.5"

however doing that py-glewpy fails to build with:

pyrexc src/glew.pyx --> src/glew.c

src/glew.c:1:2: error: #error Do not use this file, it is the result of a failed Pyrex compilation.
error: command '/usr/bin/gcc-4.0' failed with exit status 1

so it looks like theres something wrong with pyrex, what however I have no idea.

I'm enquiring with upstream.

Yeah, that's what I saw too. The pyrex + glewpy problem has been reported by Linux users as well (​http://bugs.gentoo.org/show_bug.cgi?id=198330) and I'm not sure if the bug ultimately lies with pyrex or glewpy. But this MACOSX_DEPLOYMENT_TARGET thing is the more immediate challenge. Baby steps... :)

[blb@…]

Note that the python ports record the value of MACOSX_DEPLOYMENT_TARGET (${prefix}/Library/Frameworks/Python.framework/Versions/2.*/lib/python2.*/config/Makefile). Combine that with the fact that MacPorts 1.6 didn't set MDT but 1.7 explicitly does, and that could be the cause for the issue.

It appears that glewpy is no longer under development, it hasn;t been touched in nearly three years and the mailing lists have been shutdown, so I don't think this issue can be resolved with glewpy. I was advised to use PyOpenGL in place on glewpy on the Pyrex mailing list

I've updated py-pyrex to the latest version and I no longer get the deployment target issue.

Too bad about glewpy... Thanks for looking into it and for updating py-pyrex.

[skymoo (Adam Mercer)]

Finally heard form upstream on this issue, as of 0.9.8.5 (which is the current version in MacPorts) the deployment target should not be set under normal circumstances. So I'm closing this ticket. If you experience similar problems again please reopen.
