compiling libraries with ghc

[Chris Moline]

hi, i wrote some utilities to make my coding a little easier and i put them in some libraries. then to use them i made a package conf file and added it with ghc-pkg -a. i then tried compiling them with

ghc -package-name extensions -c Foo.hs

but i am not sure i am compiling it right as i get linker errors of the form

/usr/libexec/elf/ld: cannot find -lDirectoryAndExtensions

whenever i try to compile a program that uses my libraries.

i can fix this by copying all the .o files to libFoo.a files. what is the right way to compile libraries?

sincerly,
chris moline
