Hi All. I want to build my code using -fllvm option in GHC. (ghc --make main.hs -fllvm -o lexer) Doing so I've got the warning: Warning: -fllvm is incompatible with -fPIC and -dynamic on this platform; ignoring -fllvm My system is MacOS X 10.6.7 with Xcode 4 and I've installed GHC 7.0.3 (64 bit) Any idea ? Alba.
