New submission from Kent Frazier: Using the stock Python shipped by Apple with OS X 10.9 Mavericks and XCode 5.1, Mercurial (and other Python extensions) encounter an error like:
cc -fno-strict-aliasing -fno-common -dynamic -g -Os -pipe -fno-common -fno-strict-aliasing -fwrapv -mno-fused-madd -DENABLE_DTRACE -DMACOSX -DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -DENABLE_DTRACE -pipe -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c mercurial/base85.c -o /private/var/folders/qv/tv81r5_9119bs3jwj3g2rp540000gn/T/hgtests._a6HZj/build/temp.macosx-10.9-intel-2.7/mercurial/base85.o clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future] clang: note: this will be a hard error (cannot be downgraded to a warning) in the future error: command 'cc' failed with exit status 1 make: *** [tests] Error 1 This can be worked around with: export CFLAGS=-Qunused-arguments On my machine, Python was build with clang-500.0.68 and the XCode 5.1 updates it to clang-503.0.40. I will include a simple setup.py that can be run against Mercurial's head to demonstrate the issue. ---------- components: Distutils files: toysetup.py messages: 216363 nosy: dstufft, eric.araujo, jason.coombs, kfrazier priority: normal severity: normal status: open title: distutils fails to build C extensions with XCode 5.1 and OS X 10.9 (Mavericks) type: compile error versions: Python 2.7 Added file: http://bugs.python.org/file34889/toysetup.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21244> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
