Compile source code and example in linux about ncnn HOT 7 CLOSED

Compile source code has succeed;
but Compile example failed.
g++: error: openmp: 没有那个文件或目录
g++: error: thread: 没有那个文件或目录
g++: error: test.cpp: 没有那个文件或目录
Please help me！！！ thank u

@Pratyeka Have you installed openmp? For thread, maybe use -lpthread instead. And test.cpp is the source code file.

from ncnn.

Compile source code has succeed but compile example failed(we can't find test.cpp).
so what's your test.cpp?
How can I convert the caffe-cnn to ncnn-cnn and apply them in the phone?
Thanks!

@BiranLi Hi, After I compile the ncnn source file, I write a makefile as follows:

NCNN = /home/vac/Desktop/ncnn

OPENCV = /home/vac/opencv/opencv-3.2.0

INCPATH = 		-I${NCNN}/build/install/include \
				-I${OPENCV}/modules/objdetect/include \
                -I${OPENCV}/modules/highgui/include \
                -I${OPENCV}/modules/imgproc/include \
                -I${OPENCV}/modules/core/include \
                -I${OPENCV}/modules/imgcodecs/include \
                -I${OPENCV}/modules/videoio/include

LIBS = -lopencv_core -lopencv_highgui -lopencv_imgproc  \
		-fopenmp -pthread

LIBPATH = -L${OPENCV}/build/lib

%:%.cpp
	$(CXX) $(INCPATH) $(LIBPATH) $^ ${NCNN}/build/install/lib/libncnn.a $(LIBS) -o $@

Then I type `make squeezenet```,
however, I got a error:

g++ -I/home/vac/Desktop/ncnn/build/install/include -I/home/vac/opencv/opencv-3.2.0/modules/objdetect/include -I/home/vac/opencv/opencv-3.2.0/modules/highgui/include -I/home/vac/opencv/opencv-3.2.0/modules/imgproc/include -I/home/vac/opencv/opencv-3.2.0/modules/core/include -I/home/vac/opencv/opencv-3.2.0/modules/imgcodecs/include -I/home/vac/opencv/opencv-3.2.0/modules/videoio/include -L/home/vac/opencv/opencv-3.2.0/build/lib squeezenet.cpp /home/vac/Desktop/ncnn/build/install/lib/libncnn.a -lopencv_core -lopencv_highgui -lopencv_imgproc -fopenmp -pthread -o squeezenet
/tmp/ccIJ8RWP.o: In function `main':
squeezenet.cpp:(.text+0x507): undefined reference to `cv::imread(cv::String const&, int)'
collect2: error: ld returned 1 exit status
makefile:19: recipe for target 'squeezenet' failed
make: *** [squeezenet] Error 1

It seems a ld problem, but I can pretty sure nothing wrong with my opencv address.
Any suggestion? Thank u very much.

依赖的protobuf：
sudo apt-get install protobuf-compiler
sudo apt-get install libprotobuf-dev

@Vandermode Try to modify your opencv to version 2 . My working opencv's version is 2.4.13.

from ncnn.

@Vandermode this is probably because imread was moved to opencv_imgcodecs. Try to add -lopencv_imgcodecs to linker flags
