#2127: Bad error message for FFI declaration with no -fffi flag
------------------------+---------------------------------------------------
Reporter: tim | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler (Parser)
Version: 6.8.1 | Severity: minor
Keywords: | Testcase:
Architecture: Unknown | Os: Unknown
------------------------+---------------------------------------------------
If I compile:
{{{
module Ccall where
import Foreign.C.Types
foreign import ccall "stdio.h putchar"
putchar :: CInt -> IO CInt
}}}
I get:
{{{
$ ghc-6.8.1 -c -fext-core Ccall.hs -no-recomp
Ccall.hs:5:8: parse error on input `import'
}}}
A better error message would be to suggest passing the -fffi flag.
