JavaCL on OS X Sierra

[Benjamin Horstman]

Hi,

I'm working to get JavaCL to work on OS X Sierra.

With JavaCL and BridJ 0.7.0, I experienced a hang trying to initialize JavaCL. The java stack looks like this:

JNI.loadLibrarySymbols(String) line: not available [native method]   
NativeLibrary.load(String) line: 158   
BridJ.getNativeLibrary(String, File) line: 1046   
BridJ.getNativeLibrary(String) line: 1038   
BridJ.getNativeLibrary(AnnotatedElement) line: 607   
CRuntime.getNativeLibrary(Class<?>) line: 488   
CRuntime.register(Type, NativeLibrary, CRuntime$MethodCallInfoBuilder) line: 385   
CRuntime.register(Type) line: 345   
BridJ.register(Class<?>) line: 363   
BridJ.register() line: 203   
JavaCL$OpenCLProbeLibrary.<clinit>() line: 94   
JavaCL.<clinit>() line: 120   

The C-stack looks like this:

  thread #29: tid = 0xd52e5, 0x0000000126023226 libbridj.dylib`decode_leb128 + 54, name = 'Java: UT Thread'
    frame #0: 0x0000000126023226 libbridj.dylib`decode_leb128 + 54
    frame #1: 0x0000000126023589 libbridj.dylib`visitTrie + 377
    frame #2: 0x00000001260235e4 libbridj.dylib`visitTrie + 468
    frame #3: 0x00000001260235e4 libbridj.dylib`visitTrie + 468

====tons of repeated frames

    frame #253: 0x00000001260235e4 libbridj.dylib`visitTrie + 468
    frame #254: 0x00000001260235e4 libbridj.dylib`visitTrie + 468
    frame #255: 0x00000001260235e4 libbridj.dylib`visitTrie + 468
    frame #256: 0x00000001260235e4 libbridj.dylib`visitTrie + 468
    frame #257: 0x0000000126023892 libbridj.dylib`dlSymsInit + 466
    frame #258: 0x0000000126019f3c libbridj.dylib`Java_org_bridj_JNI_loadLibrarySymbols + 124

This can be fixed by upgrading BridJ to 0.7.1-SNAPSHOT.  However, with this snapshot, it seems that there are linking errors.

Trying to rebuild JavaCL from source isn't successful either.  The code builds OK but the tests seem to fail:

I'd like to debug this further but I'm not sure where to go from here.  I used a Retina, 15-inch, Mid 2014 MBP, but I believe this issue exists on any mac with Sierra.

Here's a related discussion from the ClearCL folks:
