Subject: [Perldl] PDL::LinearAlgebra on Win7
Does anyone have experience with installation of PDL::LinearAlgebra::Real
on
Win7?
I specifically need Cholesky factorization R = chol(A) such that
transp(R)*R=A.
It appears that PDL::LinearAlgebra requires Lapack first, and Lapack in
turn
requires Intel Fortran Compiler (not free :( and Microsoft Visual studio.
Can one install Lapack with an alternative free Fortran compiler?
If it helps, there are ppm packages for PDL::LinearAlgebra at the
sisyphusion repo:
ppm install http://www.sisyphusion.tk/ppm/PDL-LinearAlgebra.ppd --force
But they're only for *64-bit* builds of perl. If you have a 32-bit perl then
you're out of luck, at present.
I have built 32-bit ppm packages of PDL::LinearAlgebra, but they crash at
runtime, and I haven't yet had time to fix this.
Would you prefer that I provide info on how I built them ? (I know I used
the MinGW port of gcc, but I'd have to check on the various hoops that I
jumped through to get the builds to succeed.)
Cheers,
Rob
