Hi Tom and community team,
Please find the attached, patch to enable the PostgreSQL project to build
successfully on AIX using GNU.
Patch(0001-Support-for-AIX-GNU-build.pg19.v12.patch)
1. PostgreSQL support on AIX begins with OS level 7.2, and is available only
when using GCC in 64‑bit mode.
2. Since AIX defaults to 32‑bit compilation, the AIX-specific template applies
the -maix64 flag to cflags, cppflags, cxxflags, and ldflags to enforce 64‑bit
builds.
3. The linker configuration ensures that only 64‑bit libraries are produced by
default.
4. This patch has to be applied on top of, [1] changes related to MAXALIGN, and
then [2] AIX meson changes.
5. To build the patch
# export AR='/usr/bin/ar -X64’
# ./configure
# gmake
Kindly let us know your feedback on the patch.
Thank you once again for all your guidance and support during this process.
Warm regards,
Sriram.
