Failed to load implementation from #50

Closed amitchandak closed 10 years ago

amitchandak commented 10 years ago

Hi, I downloaded the "zip" file from git repo and then tried to build the project using maven.

I executed " mvn package" to build the project, while running the test cases it gives these WARNINGS:

T E S T S

How can I avoid these, since these are required for achieving best performance. Thank You, Amit.

The most important thing here is BUILD SUCCESS.

You need to read the netlib-java documentation if you want to delve into the performance details, but this is an advanced topic.

Hi fommil, I went though the documentation of netlib-java and followed the steps there. 1) First installed ATLAS then added installed folder to /etc/ld.so.conf and then run ldconfig

2) I tried to install netlib-java using maven and got this o/p: [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] netlib for Java ....................................

3) After this I tried to re-install MTJ package but still the above "WARNING" exists.

Can you please help where I am going wrong? Basically I want to use MTJ with netlib-java to get the best performance.

fommil commented 10 years ago

BUILD SUCCESS. There is no problem here and I don't even know what you're typing: it sure as hell isn't running the mtj unit tests, or even yours.

If you want native binary support, that is an advanced feature that depends entirely on your system. I cannot support that for every conceivable system configuration so you are on your own if the defaults do not work for you.

For what it's worth, I got native netlib to work by including the breeze-natives package from Scala Breeze as a dependency. This might work even if you're not using Breeze. You could also look at what that package includes and see if you can copy it to get native libraries working.
