RC2 build failures on Debian: sparc
by Joachim Breitner 12 Mar '14

12 Mar '14

Hi, sparc fails differently than in RC1, and very plainly with a segmentation fault in dll-split (which happens to be the first program to be run that is compiled with stage1): https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=sparc&ver=7.8.20140… Any ideas? Anyone feeling responsible? It would be shame to loose a lot of architectures in 7.8 compared to 7.6, but I’m not a porter and don’t know much about these part of the compiler, so I have to rely on your support in fixing these problems, preferably before 7.8.1.

GHC 7.8 on ARM
by Ben Gamari 07 Mar '14

07 Mar '14

I've been accumulating some notes concerning the current status of GHC on ARM here[1]. To quote the tl;dr, GHC 7.8 should run well on ARM with the LLVM code generator and dynamic linking. The process of building GHC itself might be a bit hairy due to linker terribleness. After this, however, you’ll have fully-featured GHC installation supporting all of the modern amenities including GHCi and Template Haskell. Cheers, - Ben [1] http://bgamari.github.io/posts/2014-03-06-compiling-ghc-7.8-on-arm.html

Problem with gold linker and 7.8.1rc2

04 Mar '14

If I use the gold linker with 7.8.1rc2 (RHEL bindist), anything using network in build-depends - even if it's not used in the code - fails to build with: libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to 'sem_unlink' libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to 'sem_open' libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to 'sem_wait' libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to 'sem_getvalue' libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to 'sem_close' libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to 'sem_post' libHSunix-2.7.0.1-ghc7.8.0.20140228.so: error: undefined reference to 'sem_trywait' (I only have shared libraries on this machine.) -- View this message in context: http://haskell.1045720.n5.nabble.com/Problem-with-gold-linker-and-7-8-1rc2-… Sent from the Haskell - Glasgow-haskell-users mailing list archive at Nabble.com.

Stripping the bindist?
by harry 04 Mar '14

04 Mar '14

Should the binary distribution be stripped? Not a huge deal, but I'm saving a fair amount of space by stripping http://www.haskell.org/ghc/dist/7.8.1-rc2/ghc-7.8.0.20140228-x86_64-unknown… after installing it. -- View this message in context: http://haskell.1045720.n5.nabble.com/Stripping-the-bindist-tp5745023.html Sent from the Haskell - Glasgow-haskell-users mailing list archive at Nabble.com.
