[Haskell-cafe] GHC compilation with postres libs

[Edwin Eyan Moragas]

Hi guys,

been spending some time compiling my app but nothing seems to work.

here's the picture:
- created a Main.hsc which include some external libs.

- included this pragma is Main.hsc 
{-# OPTIONS -fglasgow-exts #-}

-compiled Main.hsc with:
$ hsc2hs -I/usr/local/pgsql/include Main.hsc
all went well with this

- tried compiling this way:
$ ghc -o test -L/usr/local/pgsql/lib Main.hs
here's the error:

Main.o(.text+0xbd): In function `r289_entry':
: undefined reference to `PQgetvalue'
Main.o(.text+0x28f): In function `r28b_entry':
: undefined reference to `PQexec'
Main.o(.text+0x42f): In function `r28d_entry':
: undefined reference to `PQreset'
Main.o(.text+0x573): In function `r28f_entry':
: undefined reference to `PQfinish'
Main.o(.text+0x6b7): In function `r28h_entry':
: undefined reference to `PQstatus'
Main.o(.text+0x82b): In function `r28j_entry':
: undefined reference to `PQconnectdb'
collect2: ld returned 1 exit status

any ideas?

kind regards,
eyan
