[Haskell-cafe] Newbie question: ghc search path for .c files

[Seth J. Fogarty]

Hi, I am having difficulty compiling a program that uses a foreign
library. The readme says to first compile a C file:

:> ghc mipFFI.c -c
mipFFI.c:1:0:  lpkit.h: No such file or directory

Alright, that's not uncommon. gcc confirms

:>  gcc mipFFI.c
mipFFI.c:1: lpkit.h: No such file or directory
mipFFI.c:2: HsFFI.h: No such file or directory

So I then include the directory and gcc finds the lpkit.h file.

:> gcc -I /home/sfogarty/lib/lp_solve_5.5 mipFFI.c
mipFFI.c:2: HsFFI.h: No such file or directory

However ghc does not seem to accept this

:> ghc -i/home/sfogarty/lib/lp_solve_5.5 mipFFI.c
mipFFI.c:1:0:  lpkit.h: No such file or directory

I've tried every variation of spacing, capitalization, copying the
files to the local directory, simply listing the files ahead. Nothing
seems to work! I am horribly confused!

And another question while I am here: -package posix and -package lang
don't seem to be included on my distribution of ghc. I am having
minimal success, as yet, finding where to download them. If I could
get a pointer, I'd be very appreciative. If not, I'm sure I'll find it
eventually.
