Issue while doing: cudnn-install / 2.4. Verifying The cuDNN Install On Linux / cudnn_samples_v7 testing

While verifying cuDNN install on Linux as the docs implied:

  1. Compile the mnistCUDNN sample. $make clean && make

I encountered error as below:

XXX@XXX ~/cudnn_samples_v7-master/mnistCUDNN $ make clean && make
rm -rf *o
rm -rf mnistCUDNN
/usr/local/cuda/bin/nvcc -ccbin g++ -I/usr/local/cuda/include -IFreeImage/include  -m64    -gencode arch=compute_30,code=sm_30 -gencode arch=compute_35,code=sm_35 -gencode arch=compute_50,code=sm_50 -gencode arch=compute_53,code=sm_53 -gencode arch=compute_53,code=compute_53 -o fp16_dev.o -c fp16_dev.cu

 #include <driver_types.h>
          ^~~~~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:200: fp16_emu.o] Error 1

I tried:

sudo find / -name driver_types.h

And I found driver_types.h is actually in

/usr/local/cuda/targets/x86_64-linux/include/

rather than

/usr/local/cuda/include .

So I replace the

CUDNN_INCLUDE_PATH ?= $(CUDA_PATH)/include

with

CUDNN_INCLUDE_PATH ?= $(CUDA_PATH)/targets/x86_64-linux/include in cudnn_samples_v7/mnistCUDNN/Makefile

And the problem was solved. I hope this would help someone.

Platform & Versions:

  • Ubuntu18.04
  • CUDA Version: 10.2
  • cuDNN Version: 7.6.5.32
Solution

  • driver_types.h is actually in /usr/local/cuda/targets/x86_64-linux/include

    Replace the

    CUDNN_INCLUDE_PATH ?= $(CUDA_PATH)/include

    with

    CUDNN_INCLUDE_PATH ?= $(CUDA_PATH)/targets/x86_64-linux/include

    in cudnn_samples_v7/mnistCUDNN/Makefile
