Hi Alvaro,
Thank you for taking your time to look into the details.
I’ve submitted the latest changes to the master branch, which are now available
in the annotations section here:
https://commitfest.postgresql.org/patch/6050/
I kindly request you to review this updated patch and share your valuable
feedback.
Regarding your observation about the inclusion of mkldexport.sh and its usage
in the makefiles — as previously
discussed, this is a necessary workaround due to current limitations on AIX. To
build shared libraries, we need to
extract symbols using this script. The relevant details are as follows:
Script Location: src/backend/port/aix/mkldexport.sh
Purpose: Implements AIX-specific changes for shared library creation using
export files.
Background: Based on discussions with the internal linker team, this method
is currently required to extract symbols and build shared libraries.
Reference Practices: This approach is consistent with methods used in other
open-source projects such as Python and OpenBLAS:
Python

OpenBLAS

As for Meson builds, we did explore them earlier but encountered some issues.
Here are some issues/fixes we submitted to the meson community
https://github.com/mesonbuild/meson/issues/14334
For now, we would like to focus initially on the regular gmake build since our
buildfarms predominantly use it. That said, we do plan to submit Meson-related
changes as a separate patch in the future.
Looking forward to your feedback.
