Dear All, I am quite new to Haskell and have only very recently found out about cabal. I am interested in some haskell packages for scientific applications, but I am experiencing some problems in installing them on my machine (ubuntu 10.04, amd64 architecture). For instance, I pasted below the output of my attempts to install hmatrix-static. Any idea about how to fix this? Cheers

hmatrix-static hasn't been brought up to ghc-6.12. I think array-0.2.0.0 doesn't build with 6.12, since some of the low-level IO stuff has been changed. The allowed versions of haskell-src-meta and hmatrix seem also not to work with 6.12. What might work is $ cabal install hmatrix (will probably install hmatrix-0.9.3.0) $ cabal unpack hmatrix-static $ cd hmatrix-static-0.3 open the .cabal file in your favourite editor, change the build-depends from array==0.2.* to array >= 0.3 && < 0.4, from haskell-src- meta>=0.0.3.1&&<0.0.7 to haskell-src-meta >= 0.1 && < 0.2 and from hmatrix==0.7* to hmatrix >= 0.9 && < 0.10, change the version of hmatrix- static to 0.3.0.1, save the changed .cabal file and then $ cabal install (no arguments) Or try to get the maintainer to do the work to get it to build with 6.12.
