Couldn't find the resource libjblas.jnilib. about jblas HOT 12 CLOSED

Hello jap226,

it seems that the the JNI files do not exist. They are not included in the sources as they are pretty large. You have to compile those from scratch, or extract them from the precompiled jar files.

See the file INSTALL under the section "COMPILING THE NATIVE PART". It might be that you also need to compile ATLAS. See the ile BUILDING_ATLAS under the heading "Mac OS X". I compiled it using mac ports.

Good luck!

Hm, on second inspection, I actually checked in the files under native-libs. Can you tell me what files you find under "native-libs".

from jblas.

There are a series of folders:
-native-libs
-static
-Linux
-Mac OS X
-Windows

if you go in the Mac OS X folder there is:
-i386
-x86_64

in the x86_64 folder there is
"libjblas_arch_flavor.jnilib"
-sse3 (a folder)
the folder "sse3" that has the file "libjblas.jnilib".

I don't remember if I mention that I am working in 64bit Java.

Thanks.

Hm... very odd, it all seems to be there. Can you send me the output of java -jar jblas-(insert your version here).jar?

Hi, I'm just running the simple test code:

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

and the output is:

Starting jBLAS EigenvalueDecomposition
checking vector addition... ok

Also, without the code:
ArchFlavor.overrideArchFlavor("SSE3");
I get the error:

Hi,
Update... I have been working on a Quad-Core MacPro with OS X 10.5.8. which is where all of these problems have been coming up. I just got a new MacBookPro with OS X 10.6.3. I tried jBLAS on this machine and it works great. No problem. (Computed eigenvalues for a 1000x1000 matrix in 0.7 seconds compared to 25 seconds for pure java implementation!)
Anyway, I don't really know what the difference would be other that the OS X version.

Hi jap226,

sorry for the problems. The machine I built jblas for is in fact a Mac OS X 10.6 machine. No idea what went wrong with 10.5, either... . Unfortunately, I'm not that much of a Mac-guy.

Anyway, have you sent me the results of "java -jar jblas-1.0.2.jar" ? Those contain a bit more logging information, in particular where it is looking for the shared libraries... .

We probably should also move the discussion over to http://groups.google.com/group/jblas-users

Hi,
I have a similar issue.
I am developing on MacOSX 10.6.4 and everything works fine. But when I deploy on a 64bit Ubuntu machine I get the following execption:

I would appreciate any ideas.

Hi,

for 64 bit Ubuntu, you need to install the gfortran runtime "sudo aptitude install libgfortran3".

The reason is that for 64bit having -fPIC (position independent code or not) is important and I cannot link the existing (static) gfortran library into jblas because it is not compiled with position independent code.

Installing the runtime should solve your problems.

Hi Mikio,
thanks for the hint. Installing libgfortran3 on that machine worked.

Thanks

Alright, I've added a warning to the configure script.

Closing the ticket now.
