作者您好！ 我在make的时候报错，找不到opencv2/opencv.cpp文件

[jxuepeng]

/media/hyzt/HYZT_Disk_3T/TensorRT-YOLOv4-master/src/../include/trt.h:13:30: fatal error: opencv2/opencv.hpp: No such file or directory
compilation terminated.
src/CMakeFiles/trt.dir/build.make:220: recipe for target 'src/CMakeFiles/trt.dir/trt.cpp.o' failed

在CMakeLists.txt里面加上 find_package( OpenCV x.x.x REQUIRED ) cmake会自动帮你找到你的版本的opencv库文件和头文件的

@liudakai2 加上这个还是不行 find_package(OpenCV 4 REQUIRED)

还是报这个错误，找不到opencv2/opencv.hpp

你试试加三级版本号，比如4.1.1，要么就不加那个4，主要是看cmake找不找得到你的opencv，然后才能make

@liudakai2 我在cmake-gui里能看见opencv的路径， cmake也能过， 但是make的时候就是找不到oepncv.hpp，都好几天了
