I'm trying to install GHC with -fPIC support in Fedora. I've grabbed a source tarball since it seems no binary one has this. In Build.mk i've changed the quick build type to ifeq "$(BuildFlavour)" "quick" SRC_HC_OPTS = -H64m -O0 -fasm -fPIC GhcStage1HcOpts = -O -fasm -fPIC GhcStage2HcOpts = -O0 -fasm -fPIC GhcLibHcOpts = -O -fasm -fPIC SplitObjs = NO HADDOCK_DOCS = NO BUILD_DOCBOOK_HTML = NO BUILD_DOCBOOK_PS = NO BUILD_DOCBOOK_PDF = NO endif unfortunately, when compiling i still get the ld error ghc -fglasgow-exts --make -shared -oHs2lib.a /tmp/Hs2lib924498/Hs2lib.hs dllmain.o -static -fno-warn-deprecated-flags -O2 -package ghc -package Hs2lib -i/home/phyx/Documents/Haskell/Hs2lib -optl-Wl,-s -funfolding-use-threshold=16 -optc-O3 -optc-ffast-math Linking a.out ... /usr/bin/ld: /tmp/Hs2lib924498/Hs2lib.o: relocation R_X86_64_32 against `ghczmprim_GHCziUnit_Z0T_closure' can not be used when making a shared object; recompile with -fPIC /tmp/Hs2lib924498/Hs2lib.o: could not read symbols: Bad value So it seems that GHC-prim still isn't compiled with -FPIC I've also told cabal to build any packages with -fPIC and shared. Anyone have any ideas? EDIT: Thanks to dcouts I've been able to make some progress. But now i'm at the point where I thnk libffi isn't compiled with -fPIC. I've edited the makefile(.in) for it but so far, no luck. The new command is: ghc -fPIC -shared dllmain.o Hs2lib.o /usr/local/lib/ghc-7.0.3/libHSrts.a -o Hs2lib.so where dllmain.c and Hs2lib.hs have both been compiled using -fPIC. The error I get is: /usr/bin/ld: /usr/local/lib/ghc-7.0.3/libHSffi.a(closures.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/ghc-7.0.3/libHSffi.a: could not read symbols: Bad value collect2
