Re: Configure: gcc problem under mingw/i386

Yes, with these steps and also later with the correction from Kyle Van Berendonck ( http://www.mail-archive.com/ghc-devs@haskell.org/msg02096.html ) it compiles on Windows too. Thanks, Nicu Am 23.08.2013 23:18, schrieb Austin Seipp:

Please update your GHC repository tree, then run:

./sync-all get

There was a bug I fixed today where 'msys' wasn't correctly detected as Windows, so it skipped the ghc-tarballs repository.

Then make sure you do './sync-all pull' to update everything else (there were other changes that require syncing.)

Hopefully that helps.

Hi all,

I'm new to GHC Dev and I'm trying to build GHC 7.7 (the repo is about 9 days old) on a Windows machine with mingw32. I followed the very helpful article for newcomers to GHC dev ( http://ghc.haskell.org/trac/ghc/wiki/Newcomers# ) and up to configure it was easy.

Now I get a problem with configure, the last few output lines are:

GHC build : i386-unknown-mingw32 GHC host : i386-unknown-mingw32 GHC target : i386-unknown-mingw32 configure: Building in-tree ghc-pwd checking for path to top of build tree... j:/ghc checking for gcc... j:/ghc/inplace/mingw/bin/gcc.exe checking whether the C compiler works... no configure: error: in `/j/ghc': configure: error: C compiler cannot create executables See `config.log' for more details

From config.log it's clear that j:/ghc/inplace/mingw/bin/gcc.exe is missing (actually already the bin is missing). My gcc is in /mingw/bin, which is in PATH, but even if I try with the option

--with-gcc=/mingw/bin/gcc

I get the same error.

So I was looking in the configure script and found out that, for mingw32 and i386, gcc must be under $hardtop/inplace/mingw/bin/, and if not, there are commands to unpack all tools from tar files like ghc-tarballs/mingw/binutils*.tar.lzma and a few others.

The point is, I don't have the subdirectory ghc-tarballs under my ghc directory.

Now, my questions:

1. Are there any reasons to not use the building tools coming from the mingw installation, and use the dedicated ones?

2. Where could I find those tarballs? Did I miss something when updated the repositories?

Thanks, Nicu
