[Haskell-cafe] Re: [hmatrix] build error

[Alberto Ruiz]

Hi Xiao-Yong,

In i686 Arch linux, with the normal blas and lapack, I need:

	extra-libraries: gsl lapack blas gslcblas gfortran

But using atlas-lapack:

	extra-libraries: gsl lapack f77blas gslcblas atlas gcc_s

I don't know how I found that "__powidf2" is in libgcc_s  :)

I will add these options to hmatrix.cabal.

-Alberto
