cannot compile matconvnet-1.0-beta25

[lgen]

When i compile matconvnet-1.0-beta25, i get the fellowing error:

警告: Version 7.0 of the CUDA toolkit could not be found. If installed, set MW_NVCC_PATH
environment variable to location of nvcc compiler.

My system setting is ubuntu16.04,cuda8.0 ,matlab2015b. And i can compile matconvnet-1.0-beta24 and matconvnet-1.0-beta23 successfully. Could you give me some help about solving this problem ? Thank you.

Ah, sorry to hear that. Are you explicitly passing the location of the cuda toolkit when you compile matconvnet? E.g. vl_compilenn(...., 'cudaRoot', 'path/to/your/cuda-8', ...) ?

Yes, i have tried, but it still doesn't work. Should i use a higher version of MATLAB ?

I'm not 100% certain to be honest, but it is worth a try if that is an option. Out of the box, I think 2015b is only guaranteed to be compatible with cuda 7.
