我正在尝试编译使用opencv 3.0的给定程序。我已经通过macports安装了opencv 2.x，并且一直在使用我的代码而没有任何问题。但是，给定的程序需要opencv 3.0，所以我必须自己安装在不同的位置，因为这个版本不能通过macports获得。在编辑opencv路径后，我尝试使用给定的makefile编译给定的程序。问题是我得到的编译错误似乎是链接问题，因为它查看位于由macports安装的2.x版本的路径中而不是在指定位置的头文件。 makefile中有一条注释，在LD_LIBRARY_PATH中包含opencv路径。我有Mac OS X 10.7.5并发现其等价物是DYLD_LIBRARY_PATH，但设置此环境变量并未更改编译器输出中的错误。我试图寻找解决方案，但没有找到任何解决方案。请帮我解决这个链接问题。提前谢谢。
这是安装opencv 3.0的地方：
/ Users / name / Desktop / opencv-master / release / opt / local /
以下是macports安装opencv 2.x的地方：
的/ opt /本地/
编译错误消息：（第一个错误发生在＆＃34; /opt/local/include/opencv2/nonfree/features2d.hpp" ，其中表示一些链接问题。）

我写道：

在 make 命令之前的终端中，但问题仍然存在。
感谢您的帮助。
答案 0 :(得分：1)
正如berak之前的评论所指出的，问题在于编译器。通过更改使用的编译器解决了此问题。这是通过编辑makefile来完成的：（CC = g ++ - mp-4.8）。
然后我在升级库文件方面遇到了一些错误，但是通过添加路径和附加＆＃34; -mt＆＃34;提升文件名，如（library not found for -lboost_system）中所述。
再次感谢，感谢您的帮助。
