[GHC] #8615: All packages built with GHC / clang are failing
#8615: All packages built with GHC / clang are failing ------------------------------------+------------------------------------- Reporter: sylvestre | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- I am trying to rebuild the Debian archive using clang instead of gcc. The biggest source of errors (622 over 2188 [1]) is related to GHC. Clang does not implement the "-u" option [2]. This is causing most (all?) of the "GHC based" packages to fail to build. with: {{{ /usr/lib/ghc/libHSrts.a(RtsStartup.o): In function `hs_exit_': (.text+0x49): undefined reference to `base_GHCziTopHandler_flushStdHandles_closure' }}} Of course, if you think it is not GHC's fault at all or there is no workaround, don't hesitate to close this bug. For example: http://clang.debian.net/logs/2013-07-14/agda_2.3.2.1-1_unstable_clang.log http://clang.debian.net/logs/2013-07-14/happy_1.18.10-2_unstable_clang.log [1] http://clang.debian.net/status.php?version=3.3&key=MISSING_OPTION_U [2] http://llvm.org/bugs/show_bug.cgi?id=18250 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8615 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

So i'm going to close it as "fixed" :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8615#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
