#7799: Assembly error while building GHC 7.7 --------------------------------+------------------------------------------- Reporter: Iceland_jack | Owner: Type: bug | Status: new Priority: normal | Component: Compiler (FFI) Version: 7.7 | Keywords: Os: Unknown/Multiple | Architecture: x86 Failure: Building GHC failed | Blockedby: Blocking: | Related: --------------------------------+------------------------------------------- Comment(by thorkilnaur): I get the same error with my: {{{ $ uname -a Linux tn24 3.2.0-39-generic #62-Ubuntu SMP Wed Feb 27 22:05:17 UTC 2013 i686 i686 i386 GNU/Linux $ ghc --version The Glorious Glasgow Haskell Compilation System, version 7.4.2 $ gcc --version gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 Copyright (C) 2011 Free Software Foundation, Inc.

As a temporary fix, adding {{{ SRC_HC_OPTS += -opta-U__i686 }}} to {{{mk/build.mk}}} enables the build to proceed.
