SageMath fails to build on on Fedora 28 with gcc 8.1 #25391
Description
SageMath 8.3.beta1 building produced 3 different errors when run on Fedora 28 64bit with gcc 8.1, specifically when building the packages:
- python 3.6.1 (fixed in Upgrade to Python 3.6.6 #25771)
- python 2.7.14 (fixed in Upgrade to Python 2.7.15 #25204)
- linbox 1.5.2 (fixed in fflas and linbox broken with gcc 8.1.0 #25353)
The 1st error manifests itself as a failure to import the crypt module during the build of Python 3.
It is due to an unspecified issue with Fedora 28 implementation of crypt(), which as reported in https://fedoraproject.org/wiki/Changes/Replace_glibc_libcrypt_with_libxcrypt is not the standard glibc implementation.
This was fixed in https://bugs.python.org/issue32635
Upstream: Fixed upstream, in a later stable release.
