Still can't run Aparapi v1.10.0 - v1.8.0 on Mac OSX (MacBook Pro 2x GPU).. but v1.7.0 works

Related to #122

Just trying out aparapi I ran the aparapi-examples .. and got the failing tests when trying to build v1.9.0 (and v1.8.0) .. since discovering #122 I tried v1.7.0 and (after turning of JavaDoc generation that for some reason failed) I can get the examples to run on my MacBook Pro.

So I thought that v1.10.0 had the bugfix for this issue and tried an example "devices in preferred order"

public class DeviceInfo {
    public static void main(String[] args) {
        KernelPreferences preferences = KernelManager.instance().getDefaultPreferences();
        System.out.println("-- Devices in preferred order --");
        for (Device device : preferences.getPreferredDevices(null)) {
            System.out.println("----------");
            System.out.println(device);
        }
    }
}

SEVERE: Check your environment. Failed to load codegen native library or possibly failed to locate opencl native library (opencl.dll/opencl.so). Ensure that OpenCL is in your PATH (windows) or in LD_LIBRARY_PATH (linux).

But this works if I change to version 1.7.0

So is this another bug than #122 or how do I use the latest version with the bugfix?
I ran the example through Intellij IDEA ..

I had the same issues running on macOS 10.13 or 10.14 for any Aparapi versions greater than 1.7.0.

If it is any help this is my Macs hardware and graphics:
its macOS Mojave v10.14.5
And it apparently has 2xggr GPUs, could it be this that throws the newer versions of aparapi?
@jchan007 does your mac also have 2 GPUs?
@freemo Just let me know if there is anything I can do to help, I'm on summer vacation this and next week but after that I'm back to work and can answer quicker. :-)

On macOS for aparapi 1.10.0 runtime UnsatisfiedLinkError with aparapi-jni 1.3.0, 1.3.1, 1.4.0, or 1.4.1, I found that using aparapi-jni 1.4.2-SNAPSHOT, resolved the issue!

commented

Definitely there is an issue with the included dynamic lib.

Could you create the aparapi-jni 1.4.2 branch and update the pom for aparapi?
Thanks a lot!

I've been working on that the past few days actually. Trying to get clang compiler to work right now so very soon i hope.

While you're awaiting the aparapi-jni 1.4.2 branch update, this worked for me by updating the Maven pom.xml dependencies to use the aparapi-jni 1.4.2-SNAPSHOT for my project:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
