Created attachment 430830 [details, diff] patch patch (metapatch?) Python 3.3 cannot be built on a Gentoo system using the musl libc because Gentoo patch 61_all_process_data.patch adds #include <linux/prctl.h> and #include <sys/prctl.h>. On a glibc system, this is superfluous, as sys/prctl.h includes linux/prctl.h already. On a musl system, this is a fatal error, because sys/prctl.h redefines a few of the macros present in linux/prctl.h. Removal of the #include <linux/prctl.h> line resolves the build error on musl and still builds fine on glibc systems.
I'm going to need your emerge --info because I haven't had any problem.
Is there any reason you're using 3.3? This patch is dropped in current versions of 3.4+. The only reason it's still in 3.3 is that nobody bumped the patchset for quite some time.
Michał: I was merging Python 3.3 primarily for coverage testing, ensuring the modules I write are compatible with 3.3 for users that still have it for whatever reason. I have no personal use for it beyond unit tests. Anthony: My emerge --info is going to look a little strange, as I've written my own profile for sake of musl testing and a few other things, so I hope that won't be an issue. I can do another test on the default embedded profile if you require it. Please do note that I am not running with ~amd64, which has a different revbump of python-3.3. That may be the difference. Also, as previously stated, I tested this on a standard run-of-the-mill glibc box running the normal KDE profile and had no issues merging it either, so I do know this patch should be safe.

Thank you for the patch but I really think we just ought to remove the patch already, like we did for other Python versions. I did this right now. commit 64b2b1f902ed3dcb5819581973b269efec5b2285 Author: Michał Górny <mgorny@gentoo.org> Date: Sat Apr 23 07:47:28 2016 dev-lang/python: Remove obsolete process_data patch from 3.3, #580242 Remove the obsolete process_data patch from both 3.3 versions. The patch was only needed for some packages using python.eclass, it is no longer carried by any other Python version (including stable ebuilds) and breaks the build on musl.
