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-makethan 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 -verboseThis 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.
