Hi,

If I understand correctly, OverloadedRecordFields has not been merged yet. Are there any chances to merge it into GHC 7.10.1?

We are pleased to announce the first release candidate for GHC 7.10.1:

https://downloads.haskell.org/~ghc/7.10.1-rc1/

This includes the source tarball and bindists for 64bit/32bit Linux and Windows. Binary builds for other platforms will be available shortly. (CentOS 6.5 binaries are not available at this time like they were for 7.8.x). These binaries and tarballs have an accompanying SHA256SUMS file signed by my GPG key id (0x3B58D86F).

We plan to make the 7.10.1 release sometime in February of 2015. We expect another RC to occur during January of 2015.

Please test as much as possible; bugs are much cheaper if we find them before the release!

Greg, thank you for this info. But it is really disappointing.

I was silent about this because it is promised that ORF is included in GHC 7.10. If I knew that active feedback was necessary, I could be vocal.

Hi Kazu, You are not the only one that is disappointed. Records have long been a wart in Haskell (and by long I mean 25+ years). Perhaps the readers of this list could read the reddit comments and propose a way forward? Dominic.

| If I understand correctly, OverloadedRecordFields has not been merged | yet. Are there any chances to merge it into GHC 7.10.1? I'm afraid not. The situation is that Adam has a fairly complete patch for overloaded record fields, but neither he nor I are happy with it. It makes some fairly complicated and pervasive changes, and feels like a sledgehammer to crack a nut. We'd scheduled for Adam to spend a day at MSR for us to work on it together, but Adam had to cancel. We'll hopefully re-arrange. Meanwhile it'd be motivating to know who, if anyone, is actively keen on it. Kazu is presumably one. I expect there are others, but I couldn't list them.

Hello lonetiger, I don't think any relevant logic changed in 7.10; however, this commit may be relevant: commit 8fb03bfd768ea0d5c666bbe07a50cb05214bbe92 Author: Ian Lynagh Sun Mar 18 11:42:31 2012 Committer: Ian Lynagh Sun Mar 18 11:42:31 2012 Original File: compiler/typecheck/TcForeign.lhs If we say we're treating StdCall as CCall, then actually do so But this warning should have applied even on older versions of GHC. Are you running x86_64 Windows? stdcall is specific to x86_32. Edward Excerpts from lonetiger's message of 2014-12-24 08:24:52 -0500:

Hi,

I’ve had some issues building this (and the git HEAD), it seems that the config.guess and config.sub in the libffi tarball is old, it doesn’t detect the platform when building with msys2. I had to unpack the tarfile and update the files, after this it correctly built.

Then I proceeded to try to make a shared library and got the following warning:

ManualCheck.hs:18:1: Warning: the 'stdcall' calling convention is unsupported on this platform, treating as ccall When checking declaration: foreign export stdcall "testFoo" testFooA :: CInt -> IO (FooPtr)

Does this mean that GHC no longer supports stdcall on windows? or could this be related to issue I had building?

Regards,

Tamar

Besides downloading a tarball, can I checkout it using git? I tried using sync-all as described on wiki [1] to checkout it: ./sync-all checkout ghc-7.10 but it seems it doesn't work, there are error message like: error: pathspec 'ghc-7.10' did not match any file(s) known to git.

Thanks Austin, looks like it is already merged in current ghc-7.10 branch: I managed to get 7.10.0.20150116 to build itself. :-) https://copr.fedoraproject.org/coprs/petersen/ghc-7.10/build/67977/

it seems to me that RC1 is not able to build itself? https://copr-be.cloud.fedoraproject.org/results/petersen/ghc-7.10/fedora-raw...
