在Xcode项目中使用OpenCV会产生链接器错误

Question

在通过他们的cmake进程构建和安装opencv之后,我采取了一些建议的步骤将库集成到Xcode项目中.

• 我在libopencv_core.dylib和libopencv_highgui.dylib的Build Phases中使用"Link Binary With Libraries"
• "标题搜索路径"包含/ usr/local/include /和/ usr/include /(opencv标题本身位于/ usr/local/include/opencv2中,我试图将其包括在内)
• "库搜索路径"包含/ usr/local/lib和/ usr/lib(opencv dylib文件位于/ usr/local/lib /)

然后我添加了一些演示opencv代码.当我运行这个项目时,我会遇到链接问题所带来的错误:

Apple Mach-O Linker Error: Undefined symbols for architecture x86_64: "_cvCvtColor", referenced from:

file在dylib上使用我包括显示我期望的:

file /usr/local/lib/libopencv_core.dylib /usr/local/lib/libopencv_core.dylib: Mach-O 64-bit dynamically linked shared library x86_64

file /usr/local/lib/libopencv_highgui.dylib /usr/local/lib/libopencv_highgui.dylib: Mach-O 64-bit dynamically linked shared library x86_64

这两个文件都是为适当的架构而构建的,并且(我认为)已正确添加到项目中.如何调试我可能遇到的其他链接器问题？我从哪里开始？

cvtColor在libopencv_imgproc.dylib中.将其添加到"Link Binary with Libraries"阶段,您应该很好.
