GCC error while building ghc-debug-stub
I was following the approach described in this blog post to play around with ghc-debug
and I ran into the following error:

I added withGhcDebug
to my application, entered a nix-shell
for the ghc-debug
repo, and got that error while building my app with stack
on an Ubuntu Linux machine. Any ideas about how to fix this?
