Hi Dominick,
which version of Fedora Linux are you on? The -fPIC message from the linker
may well be a red herring. AFAIR generating PIC is the default in GHC, at
least for dynamic libraries.
Best,

Hello,
I am getting relocation errors when building an executable (specifically, the "H" executable -- part of haskellR) under Fedora Linux, and the message says to "recompile with -fPIC".
The FAQ associated with H suggests that I switch to the gold linker (ld.gold) due to bugs in the default linker (ld.bfd), but this only changes the wording of the relocation error messages.
I have tried several strategies for satisfying the -fPIC requirement: 1. In cabal files I insert cc-options: and ghc-options: lines including -fPIC 2. To the 'cabal install' command line I add: --ghc-option=-fPIC --hsc2hs-option=-cflag=-fPIC 3. When building ghc 8.0.1 from source I modify config.mk by including: CONF_CC_OPTS += -fPIC SRC_HSC2HS_OPTS += --cflag=-fPIC CONF_CC_OPTS_STAGE0 = -fno-stack-protector -fPIC [same for STAGE1 and STAGE2]
All of this doesn't fix the problem, and the error messages still say "recompile with -fPIC".
This may be a bug, but I'm not sure where. Any ideas?
Thanks, Dominick _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
