#11780: GHC stage-2 build fails with "relocation R_X86_64_PC32 against `exitStaticPtrTable' can not be used when making a shared object" -------------------------------------+------------------------------------- Reporter: zadarnowski | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Keywords: | Operating System: Linux Architecture: x86_64 | Type of failure: Building GHC (amd64) | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- On very old versions of CentOS (5.x) running GCC 4.1.2, GHC fails to build with the following error: {{{ /usr/bin/ld: rts/dist/build/RtsStartup.dyn_o: relocation R_X86_64_PC32 against `exitStaticPtrTable' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: Bad value }}} This appears to be caused by #pragma GCC visibility push(hidden) in BeginPrivate.h. Removing the HAS_VISIBILITY_HIDDEN macro from mk/config.h results in a successful build. BeginPrivate.h contains a comment which seems to indicate similar problem occurs with GCC 4.2.1 on FreeBSD. I suggest that the #if directive in {Begin,End}Private.h be changed to cover both systems, by enabling visibility pragmas only on GCC versions higher than 4.2 as follows: {{{ #if defined(HAS_VISIBLITY_HIDDEN) && (__GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 2) }}} Old versions of CentOS are still prolific in enterprise environments so it would be great for advocacy reasons to get that fix into the next release of GHC. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11780 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
