Build failed on Ubuntu 18.04 (on mvn clean install) #33

I've tried to build JOCL on Ubuntu 18.04.

What I have done so far:

mkdir /home/<user>/JOCLRoot mkdir /home/<user>/JOCLRoot/JOCLBuild

cd /home/<user>/JOCLRoot

git clone https://github.com/gpu/JOCL.git git clone https://github.com/gpu/JOCLCommon.git

cmake-gui

cmake to /home/<user>/JOCLRoot/JOCLBuild

cd /home/<user>/JOCLRoot/JOCLBuild

make

cd /home/<user>/JOCLRoot/JOCL

mvn clean install

And on "mvn clean install" there are errors:

I think this is the important one: java.lang.UnsatisfiedLinkError: no JOCL_2_0_2-linux-x86_64 in java.library.path: [/home/<user>/JOCLRoot/JOCL/nativeLibraries]

In "/home//JOCLRoot/JOCL/nativeLibraries" I can only find the file "libJOCL_2_0_1-linux-x86_64.so"

So there is somehow a conflict between 2_0_2 and 2_0_1.

How can I fix that?

Thanks in advance for the help!

Yes, sorry, that wasn't managed cleanly: The version number in the CMake file is 2.0.1. But the version number on the Java side (specifially, the one that is encoded in CL.java) is 2.0.2. The reason for that is that there had been no changes in the native part between 2.0.1 and 2.0.1 (it was only an minor update on the Java side).

I have updated the version number via https://github.com/gpu/JOCL/commit/2335da1b782f97c7e69765b730d7af630d6ffec2 (for you, there is actually no reason to re-compile the native lib - you could just rename it from 2.0.1 to 2.0.2).

Sorry for the confusion here.
