Hi Phil,
I hope your Haskell journey so far has been enjoyable. I'm rather new
myself, but I'm pretty sure the answer to your question is:
By default, ghc doesn't try to include all the libraries that you import
when you compile with "ghc test.hs". You can either specify these manually:
"ghc test.hs -package hmatrix" or tell ghc to try and intelligently track
down all the relevant packages with: "ghc --make test.hs".
I hope that helps!

Hi,
I'm very new to Haskell and this Forum, just doing my first steps ... -- Try to use the hmatrix package for vector and matrix calculations.
The haskell compilation works (no problem in GHCi mode), the gcc however compilation fails with messages like: EFA.o: In function `r1bo_info': (.text+0x48): undefined reference to `hmatrixzm0zi10zi0zi0_NumericziVector_zdfNumVector1_closure' EFA.o: In function `r1bs_info': (.text+0x10a): undefined reference to `hmatrixzm0zi10zi0zi0_NumericziVector_zdfFractionalVector_closure'
Obviously gcc doesn't know where the according libraries are installed. Same problem with other packages.
I installed the haskell base system over debian (debian squeeze), gcc version 4.4.5. - Hmatrix and other packages are installed and build over cabel into local folder ~/.cabal/lib
Do I need to set a system path, or change cabal options or .. ?
Thanks in advance, Phil
