Hi,

I was able to build the "master" branch of ghc 8.0.1 using the instructions found here: https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows

When I switched to the "ghc-8.0" branch, though, I get the following error:

configure: error:

...

You've selected: BUILD: x86_64-w64-mingw32 (the architecture we're building on) HOST: x86_64-unknown-mingw32 (the architecture the compiler we're building will execute on) TARGET: x86_64-unknown-mingw32 (the architecture the compiler we're building will produce code for) BUILD must equal HOST; that is, we do not support building GHC itself with a cross-compiler. To cross-compile GHC itself, set TARGET: stage 1 will be a cross-compiler, and stage 2 will be the cross-compiled GHC.

Anyone know off the top of their heads what the issue is?

This is a dumb build system problem. One way to hack around it is edit libraries/Cabal/Cabal/Cabal.cabal and remove the spaces before 1.25.0.0. I thought I fixed this in HEAD so there may be a patch you could backport too. Edward Excerpts from Josh Berman's message of 2016-09-19 15:39:15 +0300:

Sorry to pester - now 'make' is failing:

I updated my cabal to be 1.25, thinking that might be the issue, but now I realize that was probably irrelevant.

Any further ideas? (This time, I searched trac before emailing... but didn't find anything).

Yeah, I cherry-picked that in, too - thanks! Build works; thanks everyone. On Mon, Sep 19, 2016 at 7:21 PM, Gabor Greif wrote:

This might help...
