-------- Original Message -------- Subject: Re: Foreign import From: "Gustavo Villavicencio" <[EMAIL PROTECTED]> Date: Tue, March 4, 2003 8:35 pm To: <[EMAIL PROTECTED]> Thanks Manuel The error message is as follows -------------------------------------- CallIncr.o: In function `sWM_entry': CallIncr.o:(.text+0xc5): undefined reference to `incr' collect2: ld returned 1 exit status -------------------------------------- where 'incr' is a toy function defined in 'mylib.h'. Obviously, in the foreign declaration I have changed 'myfun' by 'incr'. The compilation command is the typical ghc -ffi -c CallIncr.hs followed by ghc -ffi CallIncr.o which generate the previous error.
