cuda/cwc_convnet.cu: 6: cuda/cwc_convnet.cu: extern: not found

Hello, guys,

When compile ccv, I get the Error message:

cuda/cwc_convnet.cu -o cuda/cwc_convnet.o -c -O3 --use_fast_math -arch=sm_30 -D HAVE_CBLAS -D HAVE_LIBPNG -D HAVE_LIBJPEG -D HAVE_FFTW3 -D HAVE_LIBLINEAR -D HAVE_AVCODEC -D HAVE_AVFORMAT -D HAVE_SWSCALE -D HAVE_SSE2 -D HAVE_GSL -D HAVE_CUDA
cuda/cwc_convnet.cu: 6: cuda/cwc_convnet.cu: extern: not found
cuda/cwc_convnet.cu: 15: cuda/cwc_convnet.cu: Syntax error: "}" unexpected
makefile:30: recipe for target 'cuda/cwc_convnet.o' failed
make: *** [cuda/cwc_convnet.o] Error 2

My system:
ubuntu 16.04
cuda 8.0

What is the problem? Could you help me?
Thank you!

Doesn't seem like nvcc is in your $PATH otherwise it would be nvcc cuda/cwc_convnet.cu -o cuda/cwc_convnet.o -c -O3 --use_fast_math -arch=sm_30 -D HAVE_CBLAS -D HAVE_LIBPNG -D HAVE_LIBJPEG -D HAVE_FFTW3 -D HAVE_LIBLINEAR -D HAVE_AVCODEC -D HAVE_AVFORMAT -D HAVE_SWSCALE -D HAVE_SSE2 -D HAVE_GSL -D HAVE_CUDA

try which nvcc

Thank you!

I check my config.mk, and find NVCC is empty:

CC := clang
AR := ar
NVCC :=
CUDA_OBJS := cuda/cwc_convnet.o cuda/cwc_convnet_helper.o cuda/convnet/cwc_convnet_convolutional.o cuda/convnet/cwc_convnet_rnorm.o cuda/convnet/cwc_convnet_pool.o cuda/convnet/cwc_convnet_full_connect.o
DEFINE_MACROS := -D HAVE_CBLAS -D HAVE_LIBPNG -D HAVE_LIBJPEG -D HAVE_FFTW3 -D HAVE_LIBLINEAR -D HAVE_AVCODEC -D HAVE_AVFORMAT -D HAVE_SWSCALE -D USE_DISPATCH -D HAVE_SSE2 -D HAVE_GSL -D HAVE_CUDA
prefix := /usr/local
exec_prefix := ${prefix}
CFLAGS := -fblocks -msse2 $(DEFINE_MACROS) -I${prefix}/include
NVFLAGS := --use_fast_math -arch=sm_30 $(DEFINE_MACROS)
LDFLAGS := -L${exec_prefix}/lib -lm -lcblas -latlas -lpng -ljpeg -lfftw3 -lfftw3f -lpthread -llinear -lavcodec -lavformat -lswscale -ldispatch -lBlocksRuntime -lgsl -lgslcblas -lcuda -lcudart -lcublas -L/usr/local/cuda/lib64

if I force NVCC := nvcc the compile error is nvcc command not found. But I have installed cuda 8.0 and added the $PATH：

~/ccv/ccv-stable/lib$ nvcc -V

Is there any problem？ Thank you！
