JAR download for JBLAS 1.2.5

[vrdn-23]

Hi,

Kudos on maintaining and creating such an amazing library. I was wondering if it would be possible to be provided with the download links for the latest 1.2.5 version jar?

TIA

Oops. Sorry about that. Just saw that that it's available on maven central.

No worries and thanks, Vinay!

Hey @mikiobraun ,

Sorry for the quick question, but we're facing this issue when trying to run the jblas jar on one of our CentOS servers.

-bash-4.2$ java -jar jblas-1.2.5.jar 
-- org.jblas INFO jblas version is 1.2.4

Does this imply that we need to install libgfortran5 for jblas to run? This is a server where we have limited access to and need to raise a request to update any software so I want to make sure I raise the request for the right library the first time.

Please let me know if you require any other information.

Which version of CentOS are you running?

[vrdn-23]

-bash-4.2$ cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

[mikiobraun]

Okay, let me have a deeper look. For now, if 1.2.4 still works for you, I recommend you stick with that version, there were no major functionality changes in 1.2.5.

[vrdn-23]

So I have different issues when using 1.2.2. and 1.2.3.

-bash-4.2$ java -jar jblas-1.2.3.jar

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"
