New submission from Thomas Petazzoni: The build_ext logic uses sys.executable.startswith(os.path.join(sys.exec_prefix, "bin")) to determine whether we're building a third-party Python extension, or a built-in Python extension. However, this check is wrong in cross-compilation mode, because the host Python interpreter might very well be installed in its prefix, when it is used to cross-compile the target modules and extensions. The current check would mis-detect this as we're building third-party Python modules, while we are in fact building the internal Python modules of the target Python.
Therefore, use the existing sysconfig.python_build variable, which provides the information of whether we're building Python itself or not in a correct way. ---------- components: Cross-Build files: 0002-distutils-fix-build_ext-check-to-find-whether-we-re-.patch keywords: patch messages: 207806 nosy: thomas-petazzoni priority: normal severity: normal status: open title: distutils: fix build_ext check to find whether we're building Python or not type: compile error versions: Python 3.4 Added file: http://bugs.python.org/file33394/0002-distutils-fix-build_ext-check-to-find-whether-we-re-.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20212> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
