Hi Anthony, I have checked the values for m_platform/eglGetCurrentContext()/eglGetCurrentDisplay() and they are all valid values. In addition, they are consistent with the values returned from...

Hi akrolik Just to keep you updated, we have not had much time to look at this recently, hence the lack of a reply. We hope to get to this soon, however cannot give you an ETA at this time. In case...

Hi Alex, I did some test on Nexus10, both clCreateContextFromType() and clCreateContext() work. Can I have more information about this: 1. How do you build your application? (Header files,...

Hi Alex, There are two situations that might cause failure CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR (-1000) when creating cl context from gles context. 1. Invalid current context & display: You...

Hi Sheri, We were using the order -lEGL -lGLESv2 -lOpenCL originally. Using the original order this gives the CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR error, the context and display were reported by...

Hi Alex, Thanks for you feedback, can I ask what is your libOpenCL.so link to, is it directly link to libGLES_mali.so? Please try only link with libGLES_mali.so without libEGL.so and libGLESv2.so....

Hi Sheri, The symlinks for libOpenCL.so are: libOpenCL.so -> libOpenCL.so.1 libOpenCL.so.1 -> libOpenCL.so.1.1 libOpenCL.so.1.1 -> /vendor/lib/egl/libGLES_mali.so Without the -lEGL...

Hi Alex, That's odd: all the symbols are in libGLES_mali.so so it should work. Can you try to create a symlink /system/lib/libGLES_mali.so -> /vendor/lib/egl/libGLES_mali.so And to link...

Do you get the same issues if you add -lGLES_mali as your first entry? Kind Regards, Michael McGeagh
