在Mac上配置OpenCV+QT

1.安裝Xcode

    from App Store

2.安裝MacPorts(https://www.macports.org/install.php)

    注意系統版本，因為之前裝錯了版本，重裝還導致了下面的問題

    問題：Waiting for other installations to finish(參考：http://superuser.com/questions/169908/installer-hangs-on-waiting-for-other-installations-to-finish-despite-no-other)
    解決：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
    記得更新下，有點慢。(https://trac.macports.org/ticket/43228）:

    Terminal: sudo port selfupdate

3.安裝CMake

  (http://www.cmake.org/download/)

之前有安裝過但是失敗了，說是沒驗證不能運行，重新安裝了下還是有這個問題，調整了下mac的安全權限：

  (參考：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./)

發現Terminal里還是不是識別cmake指令，修改路徑并export path 也不行(http://blog.csdn.net/ikscher/article/details/8348925),

就裝了brew(http://stackoverflow.com/questions/20381128/how-to-install-homebrew-on-mac-osx):

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

然后用brew安裝了CMake(https://github.com/travis-ci/travis-ci/issues/2175)

Terminal: 

brew update

brew install cmake

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

注意下版本，解壓。

Terminal：

sudo port uninstall opencvcd opencv的目錄mkdir buildcd buildcmake -G "Unix Makefiles" ..make -j8sudo make install

編譯靜態庫(http://blogs.wcode.org/2014/10/howto-install-build-and-use-opencv-macosx-10-10/)1）打開CMake，選好opencv源碼路徑和靜態庫存放路徑2）點擊進行配置，去掉BUILD_SHARED_LIBS、BUILD_TESTS、WITH_1394、WITH_FFMPEG，添加x86_64到CMAKE_OSX_ARCHITECTURES，添加sdk到      CMAKE_OSX_SYSROOT，“/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk”3）重新配置并生成4）Terminal：cd 靜態庫目錄make (This will take awhile)sudo make install

5.設置開發者活動目錄

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

6.在Qt中使用

安裝好Qt在Qt Creator中根據需要添加庫，即可INCLUDEPATH += /usr/local/includeDEPENDPATH += /usr/local/includemacx: PRE_TARGETDEPS += /usr/local/lib/libopencv*.amacx: LIBS += -L /usr/local/lib/libopencv*開一個控制臺測試程序測試之,必要時記得加

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9 到pro里
