Running the hello world OpenCL example on mac os x 10.9 Mavericks

Question

I am trying to run the example that apple has posted in his developer library:

https://developer.apple.com/library/mac/documentation/Performance/Conceptual/OpenCL_MacProgGuide/ExampleHelloWorld/Example_HelloWorld.html#//apple_ref/doc/uid/TP40008312-CH112-SW2

I could not compile the example from the command line, until I read this thread:

How to set up Xcode to run OpenCL code, and how to verify the kernels before building

which I found very useful and helpful. But I am still having problem when I try to run it. It gives me the following output:

Created a dispatch queue using the ATI Radeon HD 6750M
Abort trap: 6

Do I have to run the executable with a specific flag? It is related to my GPU? By the way, I am using a MacBookPro from early 2011 on Mac OSX 10.9.1 Mavericks.

ATI Radeon HD 6750M is supported. May be you should try this sample code

https://developer.apple.com/library/mac/samplecode/OpenCL_Hello_World_Example/Introduction/Intro.html

For command line compile:

xcrun clang -arch x86_64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -framework OpenCL hello.c -o hello

Or you can refer to this to have a list of supported OpenCL devices on your machine How can i test for OpenCL compability?

Thank you. I will try if this compiles. – AlexNoir Jan 29 '14 at 15:51

I found that I don't need to specify `-isysroot`. It compiles, links, and runs fine without it. – Mouse Jan 17 '16 at 04:59
