Question

我使用macports和最新的Eclipse CDT安装了opencv 2.3.1。现在我正在尝试编译这段代码：

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

我完成了http://opencv.itseez.com/doc/tutorials/introduction/linux_eclipse/linux_eclipse.html的所有步骤，但编译器的输出是：

> -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

我做错了什么？

Answer 1

好吧..我自己也遇到了很多麻烦。

您需要查看为自己为这些头文件安装的opencv文件夹结构。有时他们不在安装指南告诉你的地方。

例如，在我的计算机中，我需要的大多数头文件都在：

[INSTALL DIRECTORY] / include / opencv [INSTALL DIRECTORY] / include / opencv2

但有些人在：

[INSTALL DIRECTORY] / modules / core / include / opencv2 [INSTALL DIRECTORY] / modules / highgui / include / opencv2等

你需要找到那些包含文件。然后转到IDE（eclipse）。在eclopse中，应该有一个“包含目录”的设置

将IDE设置为在您知道包含文件的目录中查找包含文件。

然后确保添加库。询问您是否需要帮助。

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包含目录。一般它们位于/ home / usr / include / opencv和/ home / usr / local /包含/ OpenCV的

找到这些文件后，您可以在Eclipse CDT中打开项目属性。选择GCC C ++编译器 - 目录并在那里添加include目录。选择GCC C ++链接器选项并通常给它库路径是/ usr / local / lib 也可以在引号中指定库，例如“cv”，“highgui”等。这将完成配置。希望它有所帮助。
