Hi Matt et al.!
Just to close the circle on this (I meant to post this several days ago), the
error ended up being the fact that getCoreFS also made a call to runGhc,
effectively creating a new environment with new session flags that needed to be
set (duh). I'm still puzzling over the nuances o
The GHC API code you give is fine, and works correctly. In the whole
reproducer there is some additional code `getCoreFS` which is where
the error comes from.

Can you put the whole example into a github repo and then I will look
at what is wrong?

Thanks, Andreas!
I will check out the hint​ package and also play with verbosity and
workingDirectory.
I considered using the Cabal library to derive the inputs from the project's
cabal file, but it does help first to know what the needful inputs are, and
where to stash them in the DynFlags se
Tbh, the current code is a bit of a Frankenstein cobbled together from the dead
limbs of online GHC API tutorials past. I think that line was the swollen
appendix of something. :)
But I can confirm that commenting out that line does not help. I get exactly
the same module graph output and error
Looks like it would work to me if you remove
```
setContext [ IIDecl $ simpleImportDecl (mkModuleName "Prelude") ]
```
Why do you have this line?

I think this is an ok forum for this kind of question. You could also

I recently played around with the ghc api and I found the `hint` package

Hi Everyone!
I'm new here, trying to learn the GHC API. using 944 with cabal 3.8.1.0.
How do I correctly set a GHC Session's DynFlags (and/or other properties) to
ensure local libraries imported by the main target are resolved properly at
compile time?
What flags need to be set so that GHC is
