Hello,
I'm using GHC 6.6.1 under Windows XP and I can't get the following simple program to compile.
import Text.Regex main = putStrLn (subRegex (mkRegex "c") "abc" "a")
It runs in GHCi just fine but GHC gives the following output when trying to compile:
project1.o(.text+0x169):fake: undefined reference to `regexzmcompatzm0zi71_Textz iRegex_mkRegex_closure' project1.o(.text+0x1f7):fake: undefined reference to `regexzmcompatzm0zi71_Textz iRegex_subRegex_closure' project1.o(.rodata+0x4):fake: undefined reference to `regexzmcompatzm0zi71_Textz iRegex_mkRegex_closure' project1.o(.rodata+0x8):fake: undefined reference to `regexzmcompatzm0zi71_Textz iRegex_subRegex_closure' collect2: ld returned 1 exit status
Use --make, or -package regex-compat. Like most compilers, GHC defaults to not linking unspecified libraries. (I've already sugested to Ian that this be changed for 6.10) Stefan
