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

[orvarehn]

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);
        }
    }
}

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 should have time to look at this tomorrow. I'm out in the city today.

Is this another bug? or how can I use the latest version with the bugfix in it?

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

[freemo]

This is quite odd as it does run for me on the latest on macOS... At least i think so. Let me try replicating this again my memory might be faulty.

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!

[bmatasar]

Definitely there is an issue with the included dynamic lib. java.lang.UnsatisfiedLinkError: /private/var/folders/lp/8y14zffn1950wmdv5hwjqmq40000gn/T/libaparapi_x86_649204007986505769813.dylib: dlopen(/private/var/folders/lp/8y14zffn1950wmdv5hwjqmq40000gn/T/libaparapi_x86_649204007986505769813.dylib, 1): no suitable image found.

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.

[jchan007]

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>
