Re: validate failure on Mac OSX for ghc head (validate fails with clang)

I put some notes on trac. I’ll see about updating build notes later. I did find some stuff in the Mach linker that needs to be handled differently on gcc vs clang on Mac. And likely needs a patch so it also builds clean with gcc On Thu, Dec 28, 2017 at 10:26 AM Ben Gamari wrote:

digging around in configure.ac it looks like i need to set CC_STAGE0 env variable to my desired CC :)

hope this helps other folks... but it definiely seems like the current logic for CC_STAGE0 is more brittle than for CC

Indeed, I've realized over the last few weeks in attempts to cross-compile GHC that our configure script is a bit... let's say peculiar in several respects.

Do record your findings on the Wiki. They will be much easier to find there than buried on ghc-devs.
