<p>Right, Hadrian knows which modules to compile and link by looking
at the .cabal files -- so when you omit a module from the .cabal
file Hadrian will fail to build the corresponding library or
executable correctly.<br>

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

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