From the looks of it, you're building with a bootstrap compiler (stage 0). Does the build compiler need to have this in its runtime libraries for the built compiler to work? This will require you to work it in in multiple versions, the first providing it without using it and the next using the provided one.

Hi,

in order to clean up my code, I've moved a bunch of stuff to a new
source file, `TcRowTys.hs` that works similar to `TcTypeNats.hs`. But
when trying to compile a clean build of GHC, I get a linker error:

```

more) => _build/stage0/bin/ghc

```

I had a look at the Wiki including the FAQ, but did not fine anything
about that topic. Does someone know what I have to do for this to work?

Cheers,
Jan
