QtOpenCL building problem with mingw (from QtSDK)



  • Hi there.

    I have read some forums but nothing helps me really, so i decide to ask here. I am using Win7 with the QtSDK (4.7.4 with mingw). I have also installed the nvidia cuda toolkit 4.0 to get all the opencl includes and libs. Now i have no Idea, how i should compile the QtOpenCL Module with the mingw. I followed this tut: http://doc.qt.nokia.com/opencl-snapshot/building.html but the Windows Building section is very little. When I type the folllowing lines at the cloned gitrepo: http://qt.gitorious.org/qt-labs/opencl

    qmake
    mingw32-make

    than the includes and libs are not found:

    @

    Shall i set some systempathes ore something like that, to let them found?

    The second try was to install the msys and run the ./configure script to set the inlcude and lib pathes like the linux how to from the site discribed above. But when i run these one, it seems to start with compiling, but it have a problem with linking:

    @
    $ ./configure -I/c/nvidia_cuda_toolkit/v4.0/include -L/c/nvidia_cuda_toolkit/v4.0/lib/x64 -lOpenCL -verbose

    This is the QtOpenCL configuration utility.

    Are there any other possibilities to compile these project with mingw and set the pathes with win7? It will be really great if anyone can help me to solve this.
