Hi all,
I had compiled opencv 2.4.11 with CUDA 7 and Cublas, there was no error at compile time.
But, I'm still not understand why no tests are available when running opencv_test_gpu:

Running opencv_perf_gpu.exe also produces a strange unexpected result :
[----------]
[ INFO ] Implementation variant: cuda.

[----------]
[ FAILURE ] Device GeForce GTX 980 is NOT compatible with current GPU module build.

Could someone helps me to find an explanation ?
Thanks.
