cannot compile with ghc-8

jwaldmann commented 8 years ago

with ghc-8.0.1, I am seeing a lot of errors like this one:

Preprocessing library hmatrix-gsl-stats-0.4.1.3...

lib/Numeric/GSL/Fitting/Linear.hs:65:51: error:

                  with actual type ‘TransRaw

      In the first argument of ‘(#|)’, namely
        ‘(fitting_linear c0 c1 chi_sq cov00 cov01 cov11) # x # y’

this is with hmatrix-0.18.0.0. It works with hmatrix-0.17.0.2, so I suggest to put this exact version bound in the cabal file, as a temporary fix.

Hi,

Thanks for the email. It looks like there's an operator from hmatrix that has changed definitions.

I'm in the middle of exams. I'll have a look in a week or so.

I've added an upper bound as suggested temporarily.

Update for new definition of apply and applyRaw from hmatrix 0.18

amcphail / hmatrix-gsl-stats

cannot compile with ghc-8 #12
