[issue33174] error building the _sha3 module with Intel 2018 compilers
William Scullin <wscul...@gmail.com> added the comment:
Hi Kenneth:
I can recreate this issue on Haswell, Skylake-X, and KNL running SLES 12, Clear
Linux, and Centos 7.5. I've tried 18.1 and 18.2. It's still present across the
board with Intel C/C++ 18.0.2.199. On the Centos 7.5.1804 image, the build will
seemingly complete, but since _sha3 didn't actually compile, the regression
tests will fail with errors of the form:
$ /dev/shm/testinstall/icc/python/3.6.5/bin/python3 -m test
ERROR:root:code for hash sha3_224 was not found.
Traceback (most recent call last):

121, in __get_openssl_constructor

AttributeError: module '_hashlib' has no attribute 'openssl_sha3_224'
During handling of the above exception, another exception occurred:

Searching about, it looks like you may have seen something similar in EasyBuild:
https://github.com/easybuilders/easybuild-easyconfigs/pull/5086
but it doesn't look like the root cause was sussed out.

[issue33174] error building the _sha3 module with Intel 2018 compilers
New submission from William Scullin <wscul...@gmail.com>: When building Python 3.6.X and later with icc (18.0.0.128 or 18.0.1.163), there's an error building the _sha3 module with any optimization level other than -O0: building '_sha3' extension icc -pthread -fPIC -Wsign-compare -Wunreachable-code -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -std=c99 -Wextra -Wno-unused-parameter -Wno-missing-field-initializers -fp-model strict -I./Include -I. -I/usr/local/include -I/derp/Python-3.6.4/Include -I/derp/Python-3.6.4 -c /derp/Python-3.6.4/Modules/_sha3/ sha3module.c -o build/temp.linux-x86_64-3.6/derp/Python-3.6.4/Modules/_sha3/sha3module.o ": internal error: ** The compiler has encountered an unexpected problem. ** Segmentation violation signal raised. ** Access violation or stack overflow.

[ jlselogin2: Python-3.6.4 ]$ dropping to -O0, compilation works every time. I haven't found disabling any particular set of optimizations to be useful in obtaining a successful build with icc. Intel has been notified and a bug filed as this is really a compiler bug. On the Python side, it does not appear possible to use Modules/Setup to drop the optimization level for just _sha3 and I'm hunting for a workaround. -- components: Installation messages: 314619 nosy: wscullin priority: normal severity: normal status: open title: error building the _sha3 module with Intel 2018 compilers type: compile error versions: Python 3.6 ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33174> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22699] cross-compilation of Python3.4
William Scullin added the comment: I thought this was originally a help request and was going to re-direct this. Cross-compile with 3.4.3 and later seems broken.
