  1. Re: clCreateFromGLTexture undef ref and kernel args

    Guys,

    I just managed to compile it. I found, over some hours surfing the web, that for the Geforce 680 you must use all the input arguments in the kernel. Unbelievable bug...

    Thank you all for...
  2. Re: clCreateFromGLTexture undef ref and kernel args

    Thats an interesting question.

    I just went over my Devce Manager, and on Display adapters I found I have an Intel(R) HD Graphics 4000 and NVIDIA Geforce GTX 680.

    Might this be the problem? is...
  3. Re: clCreateFromGLTexture undef ref and kernel args

    I tested different kernels and all of then simply aren't build when they have two or more __read_only image2d_t variables on their arguments.

    Why does this happen?
  4. Re: clCreateFromGLTexture undef ref and kernel args

    Clint,

    I was thinking the same. Its a waste of processing/reading/writing time and memory.

    So how the hell can I pass two __read_only images and one __write_only textures to the kernel ?

  5. Re: clCreateFromGLTexture undef ref and kernel args

    I was thinking in an work around.

    Is it possible to, instead of having
    texture = clCreateFromGLTexture2D(context,CL_MEM_READ_ONLY,GL_TEXTURE_2D,0,front_tex, &err1);

    have something like ...
  6. Re: clCreateFromGLTexture undef ref and kernel args

    Thanks for your reply. Ok, so I need to play with openCL 1.1.

    Yes, I am using glFinish() before the clEnqueueAcquireGLObjects() call.
  7. Re: clCreateFromGLTexture undef ref and kernel args

    this is my kernel:


    __kernel void mip( __read_only image2d_t front,
    __write_only image2d_t final ,__read_only image2d_t back
    )
    {...
  8. Re: clCreateFromGLTexture undef ref and kernel args

    as an update here's some code:



    So, len actually has the vale 2. is this normal? am I missing something?
  9. clCreateFromGLTexture undef ref and kernel args

    Hello,

    I have started to work with openCL and I have come across some weird stuff.

    First of all, I am working on windows 7, 64bit, with netbeans 7.2, mingw, and the latest NVIDIA drivers for...
