<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>
