Re: [Haskell-beginners] Installing hmatrix on OS X

Ooops. Cancel that --- I didn't get any errors on running "cabal install", and "hmatrix-0.8.2.0" is listed in my ghc-pkg list. However, on attempting to run the tests listed on: http://sites.google.com/site/wwwhmatrix/installation i.e.: (in ghci):

import Numeric.LinearAlgebra.Tests runTests 20

I get the error: ... ... Loading package hmatrix-0.8.2.0 ... linking ... <interactive>: unknown symbol `_zgemm_' ghc: unable to load package `hmatrix-0.8.2.0' Does anyone have any suggestions as to what's going on now? Thanks, Duncan On Sat, Feb 6, 2010 at 10:26 PM, Duncan Mortimer wrote:

Hi All,

Following Heinrich's advice (thanks), I found the following worked:

in hmatrix.cabal:

change "build-type: Custom" to "build-type: Simple"

and at the end of hmatrix.cabal:

change "extra-libraries:"   to   "extra-libraries: gsl" and "extra-lib-dirs: "  to   "extra-lib-dirs: /opt/local/lib/"

Then at the command line run:

cabal --extra-include-dirs=/opt/local/include configure

followed by

cabal --extra-include-dirs=/opt/local/include install

I couldn't work out how to put the extra-include-dirs details into the hmatrix.cabal file --- I kept getting the error "Warning: hmatrix.cabal: Unknown fields: extra-include-dirs".

Anyway --- the above appears to have worked for me.  I thought I'd send it back to the list in the hopes that it helps someone else.  And if anyone can explain where "extra-include-dirs" should go in the hmatrix.cabal file, please let me know! :)

best, Duncan

I'm having a similar error when trying to install HMatrix on OS X as well. Interested if anyone can find a solution.

Hi all,

I'm trying to install the easyVision library on OS X, following the notes at http://mit.edu/harold/Public/easyVisionNotes.html.

However, despite a few hours web trawling and hacking away with various cabal options, I can't get "hmatrix" to install.  I'm using OS X 10.5.8 with GHC 6.10.4.   I installed gsl using macports, as suggested in the notes above, but cabal doesn't seem to be able to find it.  The error I'm getting is:

[13:22:35 dmorti hmatrix-0.8.2.0]$ cabal install hmatrix Resolving dependencies...

The exception was: exit: ExitFailure 1

It appears that others have also had this error, but have been able to fix it up by including "--extra-lib-dirs" and "--extra-include-dirs" options, or using "ld-options: -framework vecLib".  I've tried both of these approaches, but still get the same errors.

Can anyone offer any suggestions?
