1. Install Xcodefrom App Store2. Install MacPorts (https://www.macports.org/install.php)

Pay attention to the system version, because the wrong version was installed before, and the reinstallation also caused the following problems

Question: Waiting for other installations to finish (reference: http://superuser.com/questions/169908/installer-hangs-on-waiting-for-other-installations-to-finish-despite-no-other)

Solution: Chances are that a previous installation hung and the lock was never cleaned up.

1) sudo rm / private/var/db/mds/system/mds.install.lock

2) reboot

Remember to update, it's a little slow. (https://trac.macports.org/ticket/43228):

Terminal: sudo port selfupdate

3. Install CMake (http://www.cmake.org/download/)

It has been installed before but failed. It is said that it cannot be run without verification, but there is still this problem after reinstallation. Adjust the security permissions of mac:

(reference: http://www.native-instruments.com/en/support/knowledge-base/show/949/mac-os-10.8-error-message-...-cant-be-opened-because-it-is-from-an-unidentified-developer./)

It is found that the cmake instruction is still not recognized in Terminal, and it is not possible to modify the path and export path (http://blog.csdn.net/ikscher/article/details/8348925),

Brew (http://stackoverflow.com/questions/20381128/how-to-install-homebrew-on-mac-osx):) is installed.

Terminal:ruby-e "$(curl-fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)")

Then install CMake (https://github.com/travis-ci/travis-ci/issues/2175)) with brew

Terminal:

Brew update

Brew install cmake

4. Install OpenCV (http://opencv.org/downloads.html)

Pay attention to the version and decompress it.

Terminal:

Sudo port uninstall opencvcd opencv directory mkdir buildcd buildcmake-G "Unix Makefiles".. make-j8sudo make install

Compile static library (http://blogs.wcode.org/2014/10/howto-install-build-and-use-opencv-macosx-10-10/)1) Open CMake, select the opencv source code path and static inventory path 2) Click to configure, remove BUILD_SHARED_LIBS, BUILD_TESTS, WITH_1394, WITH_FFMPEG, add x86 libraries 64 to CMAKE_OSX_ARCHITECTURES, and add sdk to CMAKE_OSX_SYSROOT "/ Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk" 3) reconfigure and generate 4) Terminal:cd static library directory make (This will take awhile) sudo make install

5. Set up developer activity directory

Teriminal:sudo / usr/bin/xcode-select-switch / Applications/Xcode.app/Contents/Developer

6. Use in Qt

Once Qt is installed, add libraries to Qt Creator as needed, then INCLUDEPATH + = / usr/local/includeDEPENDPATH + = / usr/local/includemacx: PRE_TARGETDEPS + = / usr/local/lib/libopencv*.amacx: LIBS + =-L / usr/local/lib/libopencv* open a console test program to test it, remember to add it if necessary

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9 to pro or
