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

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.
regards allan

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
