Comment(by mcandre):
Let me explain it all over again.
{{{ -lSOMELIBRARY }}} syntax is commonly used to import libraries, either
.SOs (Linux), .DLLs (Windows), or .DYLIBs (Mac).
{{{ -lSOMELIBRARY }}} verifiably works for dylibs in GHCi.
{{{
$ ghci -lcharm
GHCi, version 7.0.2: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Loading object (dynamic) charm ... done
final link ... done
Prelude>
}}}
But not GHC. The pertinent line in the verbose output is {{{ ld: library
not found for -lcharm }}}.
I am asking for GHC to accept {{{ -lSOMELIBRARY }}} instead of the weird
{{{ -dylib-install-name }}} syntax. It's inconsistent for GHCi to use one
syntax and GHC to use another. My primary preference is that they both use
{{{-lSOMELIBRARY }}}, but it would also be acceptable if they both used
{{{ -dylib-install-name }}}.
The C code to create the dylib verifiably works; there's an example at
!GitHub. https://github.com/mcandre/charm#readme
Incidentally, when the dylib is successfully imported using {{{ -dylib-
install-name }}}, there are other problems to consider.
These are reported at Haskell Cafe. http://groups.google.com/group
