The ubuntu CI seems to be ok. Failing on linter, but this is already fixed in #494.

The macos CI is failing on an expect test because previously the c compilar was only named clang and now it's clang-15.

Actually, I already opened #490 that depends on ocaml/opam-repository#27381 ; I expect to progress on both of them in a few days but I'm fine about merging this now.

Hum this is annoying... Maybe it is simply that we're not installing the latest version but clang-15 that is not the latest anymore and is thus not symlinked to clang?

Ah yes, I had seen this but I forgot 😅. Maybe we can drop this PR then since I don't think any of us actively needs CI atm.

That is the most likely cause I believe. But we could probably delete the line in the test to make it pass. (Something like ... | sed '/clang\(-1[5-9]*\)\?: error: linker command failed with exit code 1 (use -v to see invocation)/d')

Oh, I thought the executable was not found because of the new name. If it is simply displayed differently, indeed, we can suppress the line.
