2014-11-18  3.Eclipse配置OpenCV: 1).安装带有CDT的Eclipse, 使用eclipse建立一个Mac C工程，包含一个cpp文件 2). 右击工程名, 选择“ Properties ”，在属性配置页中选择，点击 C/C Build, 在下拉选项中选择 Settings. 在右边的选项卡中选择 Tool Settings 3). 2010-10-3  1).安装带有CDT的Eclipse,使用eclipse建立一个Mac C工程，包含一个cpp文件 2).右击工程名, 选择“Properties”，在属性配置页中选择，点击C/C Build, 在下拉选项中选择 Settings. 2014-10-7  如果是Mac平台，下面还有一个关于问题ld: symbol(s) not found for architecture x8664的解释可供参考： There are two implementations of the standard C library available on OS X: libstdc and libc. They are not binary compatible and libMLi3 requires. Can I remove unwanted modules from the modules folder and build an OpenCV framework for Android and iOS? 2011-2-4  Package opencv was not found in the pkg-config search path. 安装好后opencv后执行下面这条语句的时候出错： pkg-config -cflags opencv Package opencv was not found in. 2017-8-15  使用Eclipse + OpenCV + C 环境搭建需要的软件： Win7 64位 Eclipse CDT MinGW 64位 OpenCV2.4.13 使用其中的x64库1.安装MinGW 6. 博文 来自： 明天的增加的博客.
