#9421: magic number mismatch when installing 32bit on 64bit machine -------------------------------------+------------------------------------- Reporter: | Owner: MikolajKonarski | Status: new Type: bug | Milestone: Priority: normal | Version: 7.8.3 Component: Compiler | Keywords: Resolution: | Architecture: x86_64 (amd64) Operating System: Linux | Difficulty: Unknown Type of failure: Installing | Blocked By: GHC failed | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by MikolajKonarski): To work around zlib problems I had to add hsc2hs options: {{{ cabal install zlib --ghc-option="-optc-m32" --ghc-option="-opta-m32" --ghc-option="-optl-m32" --ld-option="-melf_i386" --hsc2hs-options="-- cflag=-m32 --lflag=-m32" }}} This was inspired by {{{ http://www.haskell.org/pipermail/glasgow-haskell- users/2009-November/018070.html }}} and was needed despite {{{ https://ghc.haskell.org/trac/ghc/ticket/3400#comment:16 }}} Now everything works correctly for me. Next up for testing would be a TH heavy package or just a very large application. Yesod comes to mind. Please report here if you try that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9421#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
