So this should be printed if your system can't support jblas's native
code (I can't suppress it; it's internal to jBlas.) It's a known
problem in 0.1, but it shouldn't cause test failures on 0.2-SNAPSHOT /
the main repository. can you run

> sbt "project breeze-math" test

and can you see if there's a stack trace somewhere buried in there?

The line search error is fine. I should probably call it a warning.

[Daniel Ritchie]

Nope, no stack trace.

Also, according to the error output, the tester is looking for a file whose name is something like "jblas4761480877937050966jblas.dll." However, the files that actually reside in the temp directory where it's looking are named something like "jblas494656731588471032jblas_arch_flavor.dll." Is there anything to this name mismatch, or is this definitely not the problem?

[David Hall]

It might be a problem with win64. Are you on win64?

If so, I can hopefully mess with it tonight.

Yep, that's right.

[David Hall]

Try now. I have it working on mine. FWIW, some tests fail sometimes
(GammaTest and GeometricTest, notably).

Seems to be working on my end, too. Thanks! I've also noticed the
occasional failures.
