[GHC] #8652: Cross-compiling broken for ARM/Linux target
#8652: Cross-compiling broken for ARM/Linux target ----------------------------+---------------------------------------- Reporter: kgardas | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Keywords: | Operating System: Linux Architecture: arm | Type of failure: Building GHC failed Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------+---------------------------------------- I've attempted to cross compile GHC HEAD on Ubuntu 13.10 with ubuntu's hard-float tool-chain and LLVM. I've configured GHC with: {{{ $ ./configure --target=arm-linux-gnueabihf }}} and compiling by make works till it fails with: {{{ inplace/bin/deriveConstants --gen-header -o includes/dist- derivedconstants/header/DerivedConstants.h --tmpdir includes/dist- derivedconstants/header/ --gcc-program "/usr/bin/gcc" --gcc-flag -fno- stack-protector --gcc-flag -Iincludes --gcc-flag -Iincludes/dist --gcc- flag -Iincludes/dist-derivedconstants/header --gcc-flag -Iincludes/dist- ghcconstants/header --gcc-flag -Irts --gcc-flag -fcommon --nm-program "/usr/bin/arm-linux-gnueabihf-nm" /usr/bin/arm-linux-gnueabihf-nm: includes/dist- derivedconstants/header/tmp.o: File format not recognized deriveConstants: readProcess: /usr/bin/arm-linux-gnueabihf-nm "includes /dist-derivedconstants/header/tmp.o" (exit 1): failed make[1]: *** [includes/dist-derivedconstants/header/DerivedConstants.h] Error 1 }}} As a workaround for this issue, it's possible to use --with-gcc= and this way deriveConstants gets the right cross GCC. Looks like a bug somewhere in make machinery or configure itself. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8652 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

When it is run without --with-gcc, it even generates incorrect settings file: {{{ $ cat settings [("GCC extra via C opts", " -fwrapv"), ("C compiler command", "/usr/bin/gcc"), ("C compiler flags", " -fno-stack-protector"), ("C compiler link flags", ""), ("ld command", "/usr/bin/arm-linux-gnueabihf-ld"), ("ld flags", ""), ("ld supports compact unwind", "NO"), ("ld supports build-id", "NO"), ("ld supports filelist", "NO"), ("ld is GNU ld", "YES"), ("ar command", "/usr/bin/ar"), ("ar flags", "q"), ("ar supports at file", "YES"), ("touch command", "touch"), ("dllwrap command", "/bin/false"), ("windres command", "/bin/false"), ("libtool command", "libtool"), ("perl command", "/usr/bin/perl"), ("target os", "OSLinux"), ("target arch", "ArchARM {armISA = ARMv7, armISAExt = [VFPv3,NEON], armABI = SOFTFP}"), ("target word size", "8"), ("target has GNU nonexec stack", "True"), ("target has .ident directive", "True"), ("target has subsections via symbols", "False"), ("Unregisterised", "NO"), ("LLVM llc command", "/usr/bin/llc"), ("LLVM opt command", "/usr/bin/opt") ] }}} When --with-gcc is used, then both C compiler command and also target's arch armABI field are correctly set. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8652#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
