#9007: fails to build with hardening flags enabled (relocation R_X86_64_32 against `stg_CHARLIKE_closure'...) ----------------------------------------+---------------------------------- Reporter: nomeata | Owner: nomeata Type: bug | Status: infoneeded Priority: high | Milestone: 7.8.4 Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC failed | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ----------------------------------------+---------------------------------- Comment (by rwbarton): I managed to reproduce this by making a Frankenpackage from ghc HEAD plus the debian directory from `apt-get source ghc`. Here are the flags that are being used: {{{ rwbarton@morphism:/tmp$ ghc -optl-fPIE -optl-pie -optl-Wl,-z,relro -optl- Wl,-z,now test [1 of 1] Compiling Main ( test.hs, test.o ) Linking test ... /usr/bin/ld: test.o: relocation R_X86_64_32S against `stg_bh_upd_frame_info' can not be used when making a shared object; recompile with -fPIC test.o: error adding symbols: Bad value collect2: error: ld returned 1 exit status }}} `-optl-pie` is the offending flag. (`test.hs` is just a trivial program `main = print "hi"`.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9007#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
