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.
Thanks and see u around,
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':
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
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

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
Anyone?

base isn't listed among the build-depends of the executable, so the
obvious thing is to add base to the build-depends and see what happens then
(might also be necessary for some other packages).
I'm not sure whether iterating
I did try that; after adding a bunch of packages to the .cabal file and
trying to build i get this:

I tend to install haskell packages from apt whenever possible. One such
package is unix, which appears to come provided by the ghc6 debian
package. I'm trying to cabal install lambdabot and getting the following:
$ cabal install lambdabot

Perhaps you need to add `unix' to the build-depends in your .cabal
file.
Interesting, because
