[cmake-developers] cmake on AIX

[REIX, Tony]

Hi Brad,

You said:

Yes. Tests may be OK though cmake does not work with complex package to build.

OK. Interesting. That looks the same we have here:  pthread/libstdc++.a  .
GCC on AIX is built in 4 flavors (default is 32bit, pthread, ppc64, and ppc64/pthread). However, I never saw any package built on AIX using pthread or ppc64/pthread ...
And that is an issue since we use /opt/freeware/lib or /opt/freeware/lib64 and NEVER pthread...
We have to understand why cmake is different.

Thanks !  I saw it is paged, but I missed the AIX cases.
I've had a look at: https://open.cdash.org/buildSummary.php?buildid=5415006 . However, the traces are only high-level information. On our side, we are adding traces in order to see the details for figuring out what is really done.

We have to investigate more. Both cmake build and how/why cmake fails with mariadb.

Thanks!
