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? Thanks, - Josh Berman
