[Haskell-cafe] hmatrix, Windows and GCC

[allan]

Hi

The INSTALL file in the hmatrix repository has some very clear instructions for installation on Windows.
http://perception.inf.um.es/~aruiz/darcs/hmatrix/INSTALL

However note this section at the bottom:
"Unfortunately the lapack dll supplied by the R system does not include
zgels_, zgelss_, and zgees_, so the functions depending on them
(linearSolveLS, linearSolveSVD, and schur for complex data)
will produce a "non supported in this OS" runtime error."

Of course linearSolve is exactly what you will be wanting so this won't work for you.
I ran into exactly this problem myself. I actually didn't get as far as a run-time error as I got a linker error.

I don't have any solution for you though, sorry.

regards
allan
