s/libraries/packages/g in ghc.git/.gitmodules
by Herbert Valerio Riedel 07 Aug '13

Hello GHC devs, in the current ghc.git's .gitmodules file, the entries look like ,---- | [submodule "libraries/binary"] | path = libraries/binary | url = http://darcs.haskell.org/libraries/binary.git/ `---- I'd like to normalize the urls above to use the http://darcs.haskell.org/packages/ scheme instead to match what's used in the 'packages' file as remotepaths. (the way I understand it, the /libraries/ folder is an historical artifact, and should have been obsolete for a couple of years by now -- so the new gitolite setup won't support the /libraries/ alias anymore) ...is there any reason you can think of, I should not perform this modification to the .gitmodules file? cheers, hvr

Building GHC on Mac stops

ld.gold
by Kazu Yamamoto 06 Aug '13

06 Aug '13

Hi, If I understand correctly, GHC head supports ld.gold (on Linux). But GHC got the following error: ---- % ghc -pgml=ld.gold -threaded Witty.hs [1 of 9] Compiling Types ( Types.hs, Types.o ) ... [9 of 9] Compiling Main ( Witty.hs, Witty.o ) Linking Witty ... <no location info>: Warning: Couldn't figure out linker information! Make sure you're using GNU ld, GNU gold or the built in OS X linker, etc. ld.gold: -Wl,-u,ghczmprim_GHCziTypes_Izh_static_info: unknown option ld.gold: use the --help option for usage information ---- How can I provide necessary linker information to GHC? --Kazu

"~~" in sync-all
by Kazu Yamamoto 06 Aug '13

06 Aug '13

Hi, A recent change[1] to sync-all introduces the "~~" operator of Perl. It seems to me that this operator is not supported by old Perl. % perl --version This is perl, v5.8.8 built for i386-linux-thread-multi % ./sync-all -r git://github.com/ghc --testsuite get syntax error at ./sync-all line 904, near ""pull" ~" BEGIN not safe after errors--compilation aborted at ./sync-all line 906. Sorry for using old Perl but I appreciate if this operator will be replaced with others.

Quick Cmm question
by Jan Stolarek 05 Aug '13

05 Aug '13

I have a question about this piece of Cmm code: cJI: R1 = _sGG::P32; call (stg_gc_enter_1)(R1) args: 4, res: 0, upd: 4; cJK: ... Does the call to stg_gc_enter_1 return to cJK: a) never; b) sometimes; c) always ? I'm looking at the implementation in rts/HeapStackCheck.cmm but I don't know the meaning of `jump stg_returnToSched [R1];` at the and of stg_gc_noregs. Any help will be appreciated. Janek

GHC git server issue : warning: setlocale: LC_ALL: cannot change locale (en_AU.UTF-8)
by Erik de Castro Lopo 05 Aug '13

05 Aug '13

Hi all, I'm getting the above warning messahe every time I pull from the main GHC git repo. The strange thing is that this only happens on the GHC repo, on a whole bunch of others I get no such warning. After some pretty rigorous investigation I concluded that this is actually a issues with the GHC sit server. Since I'm doing the pull over ssh, ssh passes my environment (include LC_*) to the server, but the server doesn't support en_AU.UTF-8. To explore further, I sshed into darcs.haskell.org and it seems that locales are completely broken on this machine. Not even en_US.UTF-8 is support. I suppose its not a big deal but it would be nice to fix so no one else wastes any time debugging this.

libffi-tarballs
by Richard Eisenberg 05 Aug '13

05 Aug '13

After the libffi-tarballs submodule was added, I did a ./sync-all pull, a ./sync-all get, and a git submodule update. Everything builds just fine, but I get this answer from git status: # On branch master # Untracked files: # (use "git add <file>..." to include in what will be committed) # # libffi-tarballs/ nothing added to commit but untracked files present (use "git add" to track) Is this expected? How can I fix this? Thanks! Richard

Can't "make" ghc on master
by Alfredo Di Napoli 05 Aug '13

05 Aug '13

Hello guys, I'm trying a fresh compile from master. These are the steps I've taken: $ git clone http://darcs.haskell.org/ghc.git/ $ cd ghc $ ./sync-all --testsuite get followed by: cp mk/build.mk.sample mk/build.mk <uncommenting #BuildFlavour = quick> and finally: $ perl boot $ ./configure $ make But this is what I've got in the middle of make (just posting the relevant section): https://gist.github.com/adinapoli/6154219 As you can see I'm sandboxed inside hsenv, but I can't think of any reason this being the cause of the failure. Any ideas? Sorry for the naive question, A.

libffi
by Simon Peyton-Jones 05 Aug '13

05 Aug '13

I'm trying to build HEAD. I get a problem with libffi. Not surprising because in ghc-tarballs I see git log -3 commit f190b3ce329422e13cbe1b5dad030058ca4bdda7 Author: Ian Lynagh <ian(a)well-typed.com> Date: Tue Jul 30 15:56:23 2013 +0100 Remove libffi tarball It's now in its own repo But ./sync-all get doesn't get a libffi repo. Nor is it listed in ./packages. Does anyone have any idea where this new libffi repo is, and why it isn't listed? Thanks Simon
