ABI mismatch with HLS 2.9.0.1 and GHC 9.10.1

[Kleidukos]

OS: Fedora Linux 40
Architecture: x86_64
ghcup: 0.1.30.0
GHC: 9.10.1
HLS: 2.9.0.1

When I try to run HLS in a project that I have successfully compiled with GHC 9.10.1, I get the following error message:

GHC ABIs don't match!

I get the fedora33 HLS 2.9.0.1 bindists from ghcup. However for GHC 9.10.1 I appear to have received the fedora38 bindists. Not sure why GHC needs a higher ceiling than HLS, but perhaps this plays?

I am available if you need more info about my system.

[hasufell]

Yeah. The process is broken.

Whenever we add new version bounds to the GHC metadata, we also need to update the HLS release CI!

[Kleidukos]

@hasufell Would you be interested in a CI check that forces new additions to the version bounds to update the HLS release CI?

@hasufell Would you be interested in a CI check that forces new additions to the version bounds to update the HLS release CI?

How?

[Kleidukos]

A rough way of doing so is to check if the HLS-specific files have been modified when GHC-specific files are modified, through git.
