native-engine requires glibc 2.18, but Centos 7 only has 2.17

[shanmugh]

Similar to issue #4541 the release 1.4.0-dev23 also seems to have been built on a machine with GLIBC-2.18.

Exception message: /lib64/libc.so.6: version GLIBC_2.18' not found (required by /tmp/tmpiUCwct/native_engine.so)
`
Can you update or release a version of pants.pantsbuild-.tar.gz with a GLIBC-2.17 native-engine.so?

Release containing the issue.

Thanks

have you tried 1.4.0.dev24? afaict, that contains #5202 switching to building the engine lib on centos6 which should resolve this.

Piggy-backing on this issue.

Attempted to fix this issue by using 1.4.0.dev24 and ran into the following error:

Discussed offline... it sounds like this is in reference to https://github.com/apache/aurora/blob/c85bffdd6f68312261697eee868d57069adda434/pants , which is a much older copy of the script recommended by https://www.pantsbuild.org/install.html ... possible that the source tarball of pants is being used rather than the whls.

If that's the case, then #4956 would come into play. Modern versions of pip would prefer the whls though, and not run into this.

The issue was not with the pants install script but rather missing my wheels repository in some of my configs (I believe I had misconfigured pip find-links). This forced my project to use sdists. Switching from using the sdists to whls completely solved the problem. I was able to build successfully using both dev23 and dev24.

Ok, thanks!

Thanks for the clarification @jordanly
