Python 3.8 and above fails to build with the IBM XL compiler on Power9 platforms. ## System and Environment Information ``` $ arch ppc64le ``` ``` $ echo $CC xlc -F/projects/opt/ppc64le/ibm/xlc-16.1.1.7/xlC/16.1.1/etc/xlc.cfg.rhel.7.8.gcc.8.3.0.cuda.10.1 ``` ``` $ xlc --version IBM XL C/C++ for Linux, V16.1.1 (5725-C73, 5765-J13) Version: 16.01.0001.0007 ``` ## Test Procedure ``` $ git clone g...@github.com:quellyn/cpython.git $ cd cpython $ checkout 3.8 $ ./configure --with-pydebug $ make -j2 | tee -a make.out ``` I tested for 3.7, 3.8, 3.9, 3.10, and master. In all cases the `make` failed for versions 3.8+. I've attached both the `config.log` and the make output logs for all. - Power9 architecture (ppc64le) - IBM XL C/C++ 16.1.1.7 Python 3.7 builds without issue. ---------- components: Installation files: cpython.tar.gz messages: 399296 nosy: quellyn priority: normal severity: normal status: open title: Python > 3.7 build fails with IBM XL compiler type: compile error versions: Python 3.10, Python 3.11, Python 3.7, Python 3.8, Python 3.9 Added file: https://bugs.python.org/file50207/cpython.tar.gz _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44877> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
