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 #3: 0x00000001260235e4 libbridj.dylib`visitTrie + 468
====tons of repeated frames

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:
