Configuration failed! Reason: Sorry, the OS is currently not supported

[Amit Chandak]

Hi,
I am trying to build JBLAS from source as mentioned in "BUILD_ATLAS" and INSTALL file.

After configuring "ATLAS" and "LAPACK-LITE", i am trying to configure "JBLAS" but getting this error:

checking for java, javac... ----------

I am attaching the relevant config files

Hi,
Sorry for the above post...I was able to resolve that error but now I am facing some other error :
Reason: Could not locate libraries for the following symbols: dsyev_, ATL_dgemm, dgemm_, daxpy_, cblas_daxpy, ATL_caxpy.
I think this is already discussed on forum so will try to go through them and resolve.

Thanks,
Amit.

Hi Amit,

these are all atlas specific libraries which the config couldn't find.
Have you added the atlas libs to your path?

Also, what OS are you on? SunOS?

Hi Mikio,

I was able to resolve that error, but now I an getting this error:

https://groups.google.com/forum/#!topic/jblas-users/0IsTA5ZGiJE

I have put the required ".so" files at the required paths but still same error. 

Also when I try to run the sanity check code of your jar, get this error: 

Running sanity benchmarks.

On Linux 64bit, you need additional support libraries.
You need to install libgfortran3.

For example for debian or Ubuntu, type "sudo apt-get install libgfortran3"

For more information, see https://github.com/mikiobraun/jblas/wiki/Missing-Libraries
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.jblas.NativeBlas.dgemm(CCIIID[DII[DIID[DII)V

Can you please tell me how to proceed. I tried giving the path of ".so" files extracting it from your jar but dosn't help.

Thanks,

amit.

Have you installed libgfortran3? Something like "apt-get install
libgfortran3" should work.

Yes I have, here is the required info:
(My machine is RHEL5)
lrwxrwxrwx 1 root root     20 Jun 17  2013 /usr/lib64/libgfortran.so.1 -> libgfortran.so.1.0.0
-rwxr-xr-x 1 root root 619320 May 10  2013 /usr/lib64/libgfortran.so.1.0.0

echo $LD_LIBRARY_PATH                                                                             ~
/home/jblas-matrixEvaluation/lib/static/Linux/amd64/sse3/:/apollo/package/local_1/Linux-2.6c2.5-x86_64/ATLAS/ATLAS-21.0-0/lib/:/usr/lib/gcc/x86_64-redhat-linux/4.1.2/:/usr/lib64/

Even then I got the error messages.

I've tested jblas on CentOS 6.3. I think they are version compatible
with red hat. So maybe the 5 version doesn't yet support libgfortran.
You could try to recompile jblas.

[Amit Chandak]

Will it not work withour re-compiling ? I thought if I have the required ".so" files , it should work.

[Mikio Braun]

It seems you don't have the right version. If I read the filenames
correctly, you have libgfortran.so.1, but you'd need
libgfortran.so.3...

But libgfortran is just a small support library for the fortran part,
so recompiling should link against the right one without further code
changes.

Hm. I just wonder whether you'd have to recompile ATLAS and lapack as
well. That would be quite some work, unfortunately. Hm. Which version
of Red Hat do you have exactly? I could set up a VM with the matching
centos here and try this over the next few days when I have time.

Thanks a lot Mikio. Here are the details :
cat /proc/version                                                        
Linux version 2.6.18-164.el5 (mock...@x86-003.build.bos.redhat.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) #1 SMP Tue Aug 18 15:51:48 EDT 2009
Meanwhile I will try to compile jblas with ATLAS and see if that works.
Before compiling jblas, i first need to compile ATLAS and BLAS as mentioned on your blogs ? Right ?

Thanks,
amit,.

[Mikio Braun]

Yes. First compile lapack-lite (using the version from the README, not
the newest one), then atlas, configuring it to point to the lapack
lib, then jblas.
