Hi John,

Thanks for taking the time to chime in, much appreciated!

I took a look at your repo and found that our definition of ghc-gi-gdk is almost exactly the same (sans some historical differences (eg, using gtk (v4) vs gtk+)).

Interesting! Sadly I rediscovered this and provided a very similar solution in the first message of this bug report (with the help of a similar issue in nix). imho we should adjust the goject-introspection package to include working cairo typelib files.

I'll take a closer look this evening whether or not there is some other difference that could be causing the reported build failure.

Definitely useful insight, thanks again John!

I don't foresee any issues with understanding whats going on (similarly, famous last works 😉) but if I have any questions I'll let you know in this thread.
