Has anyone been able to get BLAS/LAPACK/SciD working on Windows? If so, how? The furthest I've gotten is building SciD, downloading BLAS and LAPACK prebuilt binaries from http://icl.cs.utk.edu/lapack-for-windows/, and using Agner Fog's objconv to convert them from COFF to OMF. Then, when I try to build a trivial test program, I get: Symbol Undefined _dgetri_ Symbol Undefined _dgetrf_ Grepping my lapack binaries indicates that getri and getrf are there, but _getri_ and _getrf_ are not. It's an underscore issue. Can anyone either: 1. Tell me how to fix this? 2. Tell me where to get BLAS and LAPACK in OMF format that will "just work" with DMD?

AFAIK objconv has the +nu or a similar switch that adds underscores to symbol names. Hope that helps.

That's -nu+ actually, or alternatively -au+ which just adds aliases to existing symbols. On 2/9/11, Andrej Mitrovic <andrej.mitrovich gmail.com> wrote:AFAIK objconv has the +nu or a similar switch that adds underscores to symbol names. Hope that helps.

He wrote the original BLAS/LAPACK bindings, so he should know. -Lars

Lars, David, Did you managed to get in touch with Bill for this? If so, would you be able to provide a package with SciD including the BLAS/LAPACK in a DMD compatible format? I would also be interested in this... Are there any plans to bring more of these numerical libraries (like SciD or even basic linear alg) into Phobos? I would assume this would be very welcomed by a lot of D developers, no? Btw, Lars, many thx for your work on SciD.... fil

I would also be interested in this...I am thinking of cleaning up some small things here and there and making a 0.1 "release" in the form of an easily downloadable zip file. It will of course be a rather arbitrary development snapshot, and in no way a "finished" product, but it may make things easier for potential users. I'm not sure I want to include someone else's prebuilt libraries, but I'll be sure to add a link to the BLAS/LAPACK download David mentioned.Are there any plans to bring more of these numerical libraries (like SciD or even basic linear alg) into Phobos? I would assume this would be very welcomed by a lot of D developers, no?IMO, there should definitely be some basic linear algebra functionality in Phobos.Btw, Lars, many thx for your work on SciD....You're welcome. :) -Lars

Any other volunteers?

Good hint. I found some pre-built binaries at http://dsource.org/projects/multiarray , Bill Baxter's old project. I tested them (superficially) and they WORK on Windows w/ DMD 2.052 beta and SciD SVN. Lars, please post this zip file somewhere on your SciD site so that other Windows users who want to use SciD don't have to got through the same hassle I did to track them down.
