Makefile中的opencv=0是什么意思
时间: 2024-02-26 17:54:52 浏览: 60
在Makefile中,opencv=0可能是一个变量的赋值语句,它将变量"opencv"的值设置为0。这通常是为了控制编译过程中是否包含OpenCV库的编译选项。
如果将opencv设置为0,则编译过程中不会包含OpenCV库的编译选项,即不会链接OpenCV库,也不会包含OpenCV头文件。相反,如果将其设置为1,则编译过程中将包含OpenCV库和头文件。
需要注意的是,具体的含义可能取决于Makefile的实现和上下文。因此,需要仔细查看Makefile文件中的其他代码来确定opencv=0的确切含义。

在opencv中运行darknet需要设置opencv=1吗
在OpenCV中运行Darknet,通常需要将编译选项中的opencv设置为1。Darknet是一个用C和CUDA编写的深度学习框架,它需要OpenCV库来处理图像和视频数据。
在编译Darknet时,需要在Makefile中设置变量"OPENCV"为1,以启用OpenCV支持。如果没有设置这个变量,Darknet将无法使用OpenCV库,因此,无法处理图像和视频数据。
因此,如果您想在OpenCV中运行Darknet,需要确保在编译Darknet时设置了"OPENCV=1"。
Makefile opencv
Sure! Here's an example of a Makefile for compiling an OpenCV program:
```makefile
# Compiler
CC := g++
# Compiler flags
CFLAGS := -std=c++11 -Wall
# OpenCV libraries
OPENCV_LIBS := `pkg-config --libs opencv`
# Source files
SRCS := main.cpp
# Object files
OBJS := $(SRCS:.cpp=.o)
# Executable
EXEC := program
all: $(EXEC)
$(EXEC): $(OBJS)
$(CC) $(CFLAGS) $(OBJS) -o $@ $(OPENCV_LIBS)
%.o: %.cpp
$(CC) $(CFLAGS) -c $< -o $@
clean:
rm -f $(OBJS) $(EXEC)
```
To use this Makefile, create a file named "Makefile" in the same directory as your source files and copy the above content into it. Make sure you have OpenCV installed on your system.
Then, place your source code file (e.g., `main.cpp`) in the same directory as the Makefile. To compile your program, simply run `make` in the terminal.
This Makefile assumes that you only have one source file (`main.cpp`). If you have multiple source files, you can add them to the `SRCS` variable, separating each file with a space.
Note: This Makefile is just a basic example. You may need to modify it according to your project's specific requirements.
