Bug 527116 – bootstrap prefix fails on OS X: python-2.7.6-r1 fails to compile

• Product: Gentoo/Alt
• Status: RESOLVED FIXED

[Description Guilherme Amadio 2014-10-27 18:18:42 UTC]

Bootstrap fails on OS X Yosemite due to python compilation errors. I tried setting USE=-aqua, but it still fails to compile, with a different error. Build logs below.

Reproducible: Always

python-2.7.5-r4 build log with USE=aqua

python-2.7.5-r4 seems to compile with USE=aqua, but there is a missing symlink during installation phase that causes failure. Uploading last 1000 lines due to 1M size limit.

python-2.7.8.ebuild

I managed to compile python-2.7.8 with the attached ebuild. What did the trick was to set MACOSX_DEPLOYMENT_TARGET=10.4 (this is what's in the Makefile of a vanilla python tarball).

Below is what I changed from python-2.7.6-r1.ebuild

stripping all Prefix patches is not the solution, it will kill you further down the road.

[Comment 6 Guilherme Amadio 2014-10-31 11:59:35 UTC]

Setting MACOSX_DEPLOYMENT_TARGET=10.4 in python-2.7.6-r1.ebuild also works. I used python-2.7.8 because I went to python.org and got the most recent tarball to try to compile by hand. The patch below should make it compile, at least with USE=-aqua.

Fixed for now due to using clang for python.
