Eclipse CDT无法找到opencv 2头文件

Question

我使用macports和最新的Eclipse CDT安装了opencv 2.3.1。现在我想要编译这段代码：

>  #include <iostream.h> 
>  #include <cv.h> // or opencv.hpp, no difference 
>  
>  int main(int argc, char **argv) { 
>  
>  
>  } 

我做的http://opencv.itseez.com/doc/tutorials/introduction/linux_eclipse/linux_eclipse.html所有步骤，但编译器的输出是：

> make all Building file: ../main.cpp Invoking: GCC C++ Compiler g++ 
> -I/opt/local/include/opencv -I/opt/local/include/opencv2 -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o "main.o" "../main.cpp" In file included from

我在做什么错？

Answer 1

好的..我自己也遇到了很多麻烦。

您需要查看您自己为这些头文件安装的opencv文件夹结构。有时它们不在安装指南告诉你的位置。

在我的计算机，例如，大多数我所需的头文件的位置是：

[安装目录] /包含/ OpenCV的 [安装目录] /包含/ opencv2

但一些被中：

[安装目录] /模块/核心/包括/ opencv2 [安装目录] /模块/ highgui /包括/ opencv2等

您需要找到那些包含文件。然后去你的IDE（日食）。在eclopse中应该有一个设置“包含目录”

将您的IDE设置为在包含文件所在的目录中查找包含文件。

然后确保您添加库。询问你是否需要帮助。

Answer 2

上面列出的错误表明，您没有指定包含目录的路径。首先在安装文件夹中搜索include目录。通常它们位于/ home/usr/include/opencv和/ home/usr/local/include/opencv

定位这些文件后，您可以在Eclipse CDT中打开项目属性。选择GCC C++编译器 - 目录并在其中添加包含目录。选择GCC C++链接器选项并给出库路径，通常它是/ usr/local/lib 也用引号指定库，例如“cv”，“highgui”等。这将完成配置。 希望它有帮助。
