Matlab GPUCoder linking issue on PX2

Dear Support,

We generated CUDA code for a CNN using the GPU Coder toolbox from Matlab.
When building the cross-compiled application for PX2 we got the following error:

gen_cnn_api.cu.o: undefined reference to symbol 'cudnnActivationForward@@libcudnn.so.7

Is this function not existing anymore in CUDA 9.0?
What would be the fix?

Thanks in advance,
Sacha

Dear sacha,
Please check nm -D libcudnn.so.7 lists cudnnActivationForward function. Did you set cudnn in path ?

Command nm -D libcudnn.so.7 lists cudnnActivationForward function, and cudnn is set in path. Do you have any other sugegstions maybe?

Tnx,
