provide a pkg-config file about flint2 HOT 7 CLOSED

Yes, that would be really nice to have.

Though I'd argue that having a flint2-config tool in addition to the .pc file would also be helpful (as unfortunately, pkg-config is not available everywhere).

Also, some distros like debian think it's a good idea to add (or hack) pkgconfig files themselves which can and does lead to cross-distro breakage. If upstream provides one, then this will less likely become a problem.

@fingolfin This was a reason against pkg-config CUPS used as well, but I wonder where it comes from? They say

It does not require anything but a reasonably well working C compiler and a C library, but can use an installed glib if that is present. (A copy of recent glib2 is shipped together with pkg-config versions since 0.27, and this is sufficient for pkg-config to compile and work properly.)

although a long time ago it was just a shell script, and I wonder if this discussion is from then.

@hasufell Debian does this because pkg-config files, or some other mechanism to get the right build flags, is essential to reliable cross-compilation. Build systems like Autotools and Meson use pkg-config to find libraries this way.

I would like a pkg-config file incorporated (GMP recently got one), and although I'm not very familiar with CMake I'll try looking around.

Great, I've been waiting 6 years for this moment... day and night I have been wondering whether anyone will hear my prayers. So long I've been contemplating how people build this project and hoped to find a brother in arms. Now finally the day has come! Let's pack up, saddle our horses and move out into the night!

the problem with Flint (and Arb) is that they have home-grown build systems where adding .pc files is more work that with autotools (there is also a cmake config for Flint nowadays, but it's a bit less stable).
In SageMath we bite the bullet and spell out checks in m4, cf. https://github.com/sagemath/sage/blob/develop/build/pkgs/flint/spkg-configure.m4

• but this could have been much less painful with a .pc file.

Should be completed now.

That was quick! 😄
