Dealing with missing packages on manylinux_2_28

[abitrolly]

There is no msgpack package in manylinux_2_28 which is based on AlmaLinux 8. And I can not find where to request it. Does that mean I have to compile msgpack myself from source?

Got the answer on Reddit.

msgpack-devel is not part of RHEL/Alma repo, but it found in EPEL 8 alongside a newer version of msgpack.

After Googling around about EPEL, here is the way to enable packages from it.

dnf install -y epel-release
dnf install -y msgpack-devel

And a proposal to enable it by default pypa/manylinux#1338

EDIT: That was not enough for installing asio-devel, which required enabling maridb-devel module (https://bugs.almalinux.org/view.php?id=208&nbn=3)

dnf module enable -y mariadb-devel
dnf install asio-devel

Or as @carlwgeorge explained in Reddit.

Sometimes packages are in modules. If they aren't in a default module stream, they will be hidden from dnf by default. If you know the exact package name like in this case you can run dnf module provides asio-devel, which shows the package is part of the mariadb-devel:10.3 module. You can enable that to make asio-devel available by running dnf module enable mariadb-devel:10.3.
