In GitHub Actions I installed sudo apt install gdc-12 now inside Ubuntu 22.04, however gdc still seemed to be a small extra package that's symlinking gdc to gdc-11.

Now gdmd is picking up GDC 11 instead of GDC 12, causing issues in the build.

Is there a way to tell gdmd to use GDC 12? Right now I hacked around this by doing

sudo rm /usr/bin/gdc
sudo ln -s /usr/bin/gdc-12 /usr/bin/gdc

but if this wasn't a CI, I wouldn't really wanna do this.

Would it be possible to provide extra gdmd scripts like gdmd-12 that pick gdc-12 on Ubuntu?

see commit https://github.com/dlang-community/libdparse/commit/03099519982c10b9d7831771bcb744f06b727400

Since this is manual DMD invocation, and not dub, I can't just specify gdc-12 as compiler.

I imagine what you're seeing is gdmd using the correct version of the compiler, just not the one you wanted.

I have multiple GDCs installed through apt, how do I make gdmd pick the higher one (gdc-12) and not just gdc?

With e.g. ln -s gdmd /usr/bin/gdmd-12, and then using gdmd-12. As shown by the few linked lines in the Perl script, the gdmd script invoked as [prefix-][g]dmd[-suffix] invokes a [prefix-]gdc[-suffix] in the same directory.

Correct, sparc-gdmd invokes sparc-gdc; gdmd-latest invokes gdc-latest, and so on and so forth.
