Haskell on Debian - gcc compilation problem with cabal installed libs like hmatrix, etc.
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 .. ?

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 Jason, many,many thanks - it works. -- u saved the day Haskell rather seems like a steeper slope to be honest, but I find the whole language concept very fascinating. What I can't imagine yet, how to address typical oo-problems especially when its "not allowed" to update and change variables ...

Phil,
I found Haskell to be a pretty steep slope at first too, but it helped me to
start out small and work my way up. And now its my favorite tool in the
arsenal!
One of the steps I took was to do quite a few of the Project Euler (
http://projecteuler.net/) problems, and then after cobbling together my own
solution (sometimes with small peeks at the Project Euler Haskell Solutions
(http://www.haskell.org/haskellwiki/Euler_problems)) I could see all the
other Haskell solutions in the forums.
As far as scientific style programming goes, I liked this tutorial which
walks you through an entire program including a section on simulated
annealing: http://www.lisperati.com/haskell/.
http://www.lisperati.com/haskell/In the large, I really liked this
haskell-cafe response by Jonathan in regards to complete programs in
Haskell: http://www.mail-archive.com/haskell-cafe@haskell.org/msg85374.html
.

Hi Henk-Jan, thanks for the advice - using hmatrix already worked, but only with simple matrices. I'll check the dependencies thanks. Hi Jason, thanks a lot for the response. Looks like I found a like minded soul. These links indeed sound very relevent for me.

Obviously gcc doesn't know where the according libraries are installed. Same problem with other packages.
The description of the package states: "internally implemented using GSL, BLAS and LAPACK"; I suppose you need to install these (non-Haskell) packages first. Regards, Henk-Jan van Tuyl -- http://Van.Tuyl.eu/ http://members.chello.nl/hjgtuyl/tourdemonad.html --
