    Default Problem building OpenCL with Mingw

    Hi,

    I am trying to build QtOpenCL from git using Qt Creator 2.4.1 using:

    Qt Code: 
    1. cd C:\OpenCL
    2. qmake opencl.pro
    3. mingw32-make
    To copy to clipboard, switch view to plain text mode 


    Unfortunately, I am getting the error you can see here:

    Qt Code:

    2. qclkernel.h:368: error: 'clSetKernelArg' was not declared in this scope

    You do have OpenCL built, installed and somewhere that it can be found, don't you? Since you are building on Windows you may have to adjust the PRO file so it can find the OpenCL includes (what's missing here I guess) and libraries (the next thing that will break).

    Thanks Chris for the help I appreciate it,

    I was able to add the include, but then I am getting another errors related to cl.h and cl_platform.h
    Qt Code: 
    1. C:\OpenCL\examples\opencl\colorize\..\..\..\src\opencl\qclglobal.h:88: error: CL/cl_platform.h: No such file or directory
    2.  
    3. C:\OpenCL\examples\opencl\colorize\..\..\..\src\opencl\qclglobal.h:89: error: CL/cl.h: No such file or directory
    To copy to clipboard, switch view to plain text mode 

    Is it the same problem related to libraries you were talking about? Could you tell which library is missing please?

    Yes. QtOpenCL is built on top of OpenCL, and these errors look like you do not have OpenCL installed.

    If OpenCL is built and installed then you may need to adjust the INCLUDEPATH entry in the QtOpenCL pro file in order that things like these includes are found. You would also need to adjust the LIBS variable so that link libraires can be found.
