I was planning to recompile everything (ATLAS, LAPACK and GHC included) this weekend, so I can have a similar environment on Windows and Linux... Having to "borrow" libraries Since I am married, this means it will actually happen on some weekend till 2010. What I really would like to try is a (purely?) functional approach to create a (P)LU decomposition of a matrix. I am not too much worried (at first) with performance or memory constraints, since I only want to see how beautiful it gets (or not!). (This one might happen somewhere in this century...) Thanks anyway On Wed, Jan 28, 2009 at 07:57, allan wrote:

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/INSTALLhttp://perception.inf.um.es/%7Earuiz/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.

Hi all,

I am writing a program that uses hmatrix for solving some linear systems. The hmatrix package depends on BLAS, which, in turn, depend on GCC 4.2 to be built (at least ATLAS does).

GHC 6.10 for Windows is pre-packaged with GCC 3.4.5, and it leaves me with the impression that I would have incompatible ABIs.

My questions:

1) Why GHC 6.10 still uses GCC 3.4.5 in Windows? I know mingw considers GCC 4.2 to be alpha, but, lets face it, 4.2 is almost obsolete! 2) Is it possible to rebuild GHC 6.10, using Windows and GCC 4.2? Is there any guide for doing this? 3) Has any of you tried hmatrix on Windows? How did you do it?

Thanks,

Rafael

Note also the next sentence: "If you find an alternative free and complete lapack.dll which works well for this system please let me know." Perhaps some Windows expert can give advice on the required dll's for Haskell programs using LAPACK in Windows. Thanks, Alberto
