Re: pg_config header files are missing - Postgres 13 - Amazon Linux 2

[Hasan Marzooq <engr.naqvi@xxxxxxxxx>]

This problem posted in OP is resolved. I did some workaround. I copied the required "pg_config*.h" from another machine where PG13 was installed via amazon linux 2 repos.

I'm not sure whether it worked "by chance" or otherwise, because it looks like Amazon Linux 2 is based on "RHEL 7" as per below:

Note the "ID_LIKE": 

----

# cat /etc/*elease
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
Amazon Linux release 2 (Karoo)

----

And:

---

# rpm -E %{rhel}
7

----

Thanks!

> Postgres 9.6 on this machine (Amazon Linux 2) is installed via PGDG repo, so I tried installing Postgres 13 as well, and I can see it has installed but only one more package I need that is "postgresql13-devel.x86_64" which needs another dependency " llvm-toolset-7-clang >= 4.0.1" that is not available from the same repo.

I don't believe 9.6 was supported either, but it may have worked "by chance".

The llvm dependency comes from the JIT functionality, which was added
in PostgreSQL 11, so it not being a dependency in an older version
than that makes perfect sense.
