[issue28092] Build failure for 3.6 on Centos 5.11

[Nick Coghlan]

Nick Coghlan added the comment:

While manylinux1 requires that compliant binaries *run* when linked against the GCC 4.2 binaries, the actual recommended compiler version (and the one used in the reference Docker image) is 4.8.2: https://www.python.org/dev/peps/pep-0513/#compilation-of-compliant-wheels

That's the compiler version in Red Hat's Developer Toolset 2, the last version to support RHEL/CentOS 5.

Unfortunately, softwarecollections.org only goes back to RHEL/CentOS 6, so the devtoolset RPMs are available via Tru Huynh's personal account on the CentOS file server: https://people.centos.org/tru/devtools-2/readme

So if 3.6 compiles and runs on CentOS 5 with GCC 4.8.2, that's sufficiently compatible for manylinux1 purposes.
