Dear Wolfram, This has come a bit in the last few weeks, to quote @boegel from https://github.com/easybuilders/easybuild/issues/619:
Already fixed in easybuilders/easybuild-framework#3303<https://github.com/easybuilders/easybuild-framework/pull/3303>, so closing. The fix will be included with the upcoming EasyBuild v4.2.1 release (or you can manually apply the fix from https://github.com/easybuilders/easybuild-framework/pull/3303/files#diff-80e271b8fd31ff4cff170771374ccbe2 to your EasyBuild installation. @golivag<https://github.com/golivag> @ptthiem<https://github.com/ptthiem> The problem should only manifest itself when trying to download sources from PyPI. As a workaround, you can manually downloaded the source tarball yourself, and put in the "source path" where EasyBuild looks for pre-downloaded source tarballs (see output of eb --show-config for the source path location). Hope that helps, Alan On Mon, 4 May 2020 at 15:57, Wolfram Zieger <[email protected]<mailto:[email protected]>> wrote: Hello there, Has anyone an idea why building * Python/2.7.16-GCCcore-8.3.0 * Python/3.7.4-GCCcore-8.3.0 as provided upstream on https://github.com/easybuilders/easybuild-easyconfigs/tree/master/easybuild/easyconfigs/p/Python (Master branch) will fail at least in the combination * foss/2019b * EasyBuild/4.2.0 * RHEL 7.7 (and propably but not testet Centos7.7) ? Replacing OS OpenSSL with easybuilds foss-2019b OpenSSL is not helping here. The thing is: When removing "exts_default_options" and all "exts_list"-content both Pythons will build just fine. Just inserting the PIP extensions is enough to make it fail (tested on Python 3). The Python traceback looks like this on both Python-Versions (example from Python2.17.16). ____________________________________________________________________________________ == building and installing Python/2.7.16-GCCcore-8.3.0... == fetching files...
