[Haskell-cafe] ghc --make unable to find dynamic library, but ghci can

[Duane Johnson]

Hi Haskellers,

This is related to my previous message, "Linking hmatrix without  
LAPACK".  Apparently, ghc --make is not finding the lapack.dylib  
library where ghci is (dylib is Mac OS X specific) .  For example, the  
following test module does NOT work when compiled with ghc --make:


> module Main where
>  import Numeric.LinearAlgebra.Tests
>
>  main = do
>    runTests 20


But the following runs fine in ghci:


> $ ghci
> GHCi, version 6.10.1: http://www.haskell.org/ghc/  :? for help
> [...loading packages...]
> Prelude> :m Numeric.LinearAlgebra.Tests
> Prelude Numeric.LinearAlgebra.Tests> runTests 20
> [...loading packages...]
> ------ mult
> OK, passed 100 tests.
> OK, passed 100 tests.
> [...more tests pass...]


Can anyone point me in the right direction?

Thank you,
Duane Johnson
