New submission from Phil Thompson <p...@riverbankcomputing.com>:
I am running macOS v11 (Big Sur) and using Xcode v12.1 (because this is the latest that includes SDK v10.15 rather than v11) to build a C extension. I'm using the older SDK because of 3rd party libraries that are not tested against the newer SDK. This version of Xcode/SDK does not support universal2 binaries. However because _supports_arm64_builds() in _osx_support only tests the macOS version and not the SDK version it returns True which means that distutils does not call compiler_fixup() to remove the '-arch arm64'. The compilation then fails. Should this work, or does Python v3.10 require SDK v11? ---------- components: Distutils messages: 396377 nosy: dstufft, eric.araujo, philthompson10 priority: normal severity: normal status: open title: Building a C extension on Big Sur and SDK v10.15 fails type: behavior versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44492> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
