Couldn't find the resource libjblas.jnilib

[Jesse]

Hi, I'm moving this from the GitHub website. We've determined that
is it is some problem with Mac OS X 10.5 as I have also tried the
jBLAS libraries on a Mac OS X 10.6 and it worked great. (I am very
impress with the speed!)

On the Mac OS X 10.5, I tried the tests....

SanityChecks.checkVectorAddition();
SanityChecks.checkEigenvalues();

Starting jBLAS EigenvalueDecomposition
checking vector addition... ok

if you tell it to override the ArchFlavor, that seems to take care of
that problem and the new issue is finding the native libraries....


SanityChecks.checkVectorAddition();
ArchFlavor.overrideArchFlavor("SSE3");
SanityChecks.checkEigenvalues();

The output is:

Starting jBLAS EigenvalueDecomposition
checking vector addition... ok

Hi Jesse,

I've searched around the web a bit, and it seems to be a general
problem when compiling on 10.6.x for 10.5.x systems. Apparently, they
added a few new features to the dynamic linking procedure which is not
recognized on 10.5.x.

Here is a link to a discussion on the topic:

http://stackoverflow.com/questions/1440456/static-libraries-in-version-cross-compiled-program

It seems that passing "-no_compact_linkedit" to the linker might help,
although I don't have the means to verify that. Alternatively, one
would have to recompile everything on a 10.5.x system.

I'll try to recompile jblas with the above option and then you could
try out that jar file. Alternatively, you could upgrade to 10.6.x of
course ;)

-M
