RE: Cannot build with Hadrian

      Hi Eric,

Good to hear you managed to build GHC both with Make and Hadrian.

Best wishes with your first GHC patch!

Cheers,
Andrey

Andrey,
I had already deleted the folder and tried again with make, which was successful. But since I sent the email, I figured I'd try again with hadrian as well. I followed exactly what I did above (which is what I did the first time, too) and it worked fine. *shrug*

Thanks anyway!
Eric

Hi Eric,

Can you show the contents of the "libffi-tarballs" directory in your GHC tree?

This error says it expects exactly one libffi tarball to be there, but it got either 0 or more than 1. I guess there is just no tarball there in your case.

Perhaps git clone failed to complete properly?

Cheers,
Andrey

GHC newcomer here -- attempting to work on my first patch.

I decided to try Hadrian, but ran into a problem.

I think I obtained the source using
...
git clone --recursive https://gitlab.haskell.org/ghc/ghc
Then:
./boot && ./configure
hadrian/build.sh -j --flavour=devel2
This ran for maybe 15 minutes, then showed the error below. Apparently I
ended up with too many tarballs? Any suggestions?

Thanks,
Eric
