c++ - Mac 库链接

标签 c++ macos opencv gcc linker

我正在尝试编译一个使用 opencv 3.0 的给定程序。我已经通过 macports 安装了 opencv 2.x，并且一直在我的代码中使用它，没有任何问题。然而，给定的程序需要 opencv 3.0，所以我不得不自己将它安装在一些不同的位置，因为这个版本无法通过 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 macports 安装的 2.x 版本路径中的头文件，而不是在指定位置。 makefile 中有一条注释，将 opencv 路径包含在 LD_LIBRARY_PATH 中。我有 Mac OS X 10.7.5，发现它的等价物是 DYLD_LIBRARY_PATH，但是设置这个环境变量并没有改变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。提前致谢。

这里是opencv 3.0的安装位置:

/用户/名称/Desktop/opencv-master/release/opt/local/

这里是macports安装opencv 2.x的地方:

/选择/本地/

编译错误信息:(第一个错误出现在"/opt/local/include/opencv2/nonfree/features2d.hpp"，说明链接有问题。 )

在ma​​ke命令之前在终端中，但问题依然存在。

感谢您的帮助。

最佳答案

正如 berak 在之前的评论中所指出的，问题出在编译器上。通过更改使用的编译器解决了此问题。这是通过编辑 makefile 完成的:(CC = g++-mp-4.8)。

然后我得到了一些关于 boost 库文件的错误，但是通过添加它的路径并附加“-mt”来提升文件名来解决这个问题，如 ( library not found for -lboost_system ) 中的回答。

再次感谢，感谢您的帮助。
