找不到 -lippicv 的库

Question

在我的OSX上安装opencv3后，我运行此命令

 g++ -ggdb `pkg-config --cflags --libs opencv` facedetect.cpp -o /tmp/test && /tmp/test

我收到此错误

  ld: library not found for -lippicv
  clang: error: linker command failed with exit code 1 (use -v to see invocation)

如果您正在使用Mac OSX

进行编译，我遇到了同样的问题，并在"在Mac OSX上使用brew安装OpenCV 3"，"故障排除"下找到了解决方案：

# Find ippicv 
find /usr/local -name "libippicv.a"
# For me it is /usr/local/Cellar/opencv3/3.1.0_3/share/OpenCV/3rdparty/lib/libippicv.a
# Make a symlink to /usr/local/lib 
ln -s /some/path/OpenCV/3rdparty/lib/libippicv.a /usr/local/lib/
# I used
ln -s /usr/local/Cellar/opencv3/3.1.0_3/share/OpenCV/3rdparty/lib/libippicv.a /usr/local/lib/
