Are there any downsides to doing this except slightly bigger binary size?

There are license issues if you want to distribute the resulting stuff. Have to ask your lawyers about lgpl + gmp + shipping binary only stuff. On the technical side, there are no other downsides.

Sorry, you're correct, I did not pass interactive. Find attached the strace with --interactive.

Actually, I'm doing this already:

https://github.com/Fuuzetsu/nix-project-defaults/blob/master/ghc/default.nix

At the end of your strace, I see this: Loading package integer-gmp ... [pid 10676] [...]

So you can see that it tries to read libgmp from a lot of places, but not from the one you specified in build.mk, so this seems to be a build system bug.

The last commit in GHC that I tried and succeeded to compile 2 weeks ago with a very similar setup as yours was this: 12332f1add3eb9615a62abb36898819b2e67e865

Can you please try that so we can rule on whether there was a change very recently that broke this.

I am even running 'patchPhase && configurePhase && buildPhase' which should technically be exactly what nix does with the package in nixpkgs. By the way, the official nix package for HEAD isn't quite HEAD but instead a snapshot of somewhere near HEAD and in fact I'm the person that opened an issue and a PR to get that updated. The fact that it builds that but doesn't build when I'm in the source tree makes me wonder what's different.

I see. I'm flying out in 10 hours for vacation, so won't have time to reproduce your issue and look into this more deeply. If you figure out what's happening, please send me a summary.

Enjoy your vacation.

Maybe you should move this thread to the gmane.linux.distributions.nixos mailing list from here, because I guess Peter Simons and co can help you more with this, than GHC devs.

Perhaps I should. I have tried with --with-intree-gmp and DYNAMIC_BY_DEFAULT=OFF and they both fail at the same time. Next stop is to try to build from some snapshots to see whether the problem is recent.

...

If I find the bandwidth during travels, I will try to keep an eye on this.

Today I built the snapshots from 20140430[1] and 20140510[2] without a problem (just had to not build the postscript docs as those failed) which makes me think there's either something wrong with my tree or these snapshots do something that stops the problem from coming up.
