在Mac上配置OpenCV+QT-创新互联

1.安装Xcode

    from App Store

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

  注意系统版本，因为之前装错了版本，重装还导致了下面的问题

  问题：Waiting for other installations to finish(参考：http://superuser.com/questions/169908/installer-hangs-on-waiting-for-other-installations-to-finish-despite-no-other)
  解决：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
  记得更新下，有点慢。(https://trac.macports.org/ticket/43228）:

  Terminal: sudo port selfupdate

3.安装CMake

  (http://www.cmake.org/download/)

之前有安装过但是失败了，说是没验证不能运行，重新安装了下还是有这个问题，调整了下mac的安全权限：

  (参考：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./)

发现Terminal里还是不是识别cmake指令，修改路径并export path 也不行(http://blog.csdn.net/ikscher/article/details/8348925),

就装了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安装了CMake(https://github.com/travis-ci/travis-ci/issues/2175)

Terminal:

brew update

brew install cmake

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

注意下版本，解压。

Terminal：

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

编译静态库(http://blogs.wcode.org/2014/10/howto-install-build-and-use-opencv-macosx-10-10/)1）打开CMake，选好opencv源码路径和静态库存放路径2）点击进行配置，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 静态库目录make (This will take awhile)sudo make install

5.设置开发者活动目录

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

6.在Qt中使用

安装好Qt在Qt Creator中根据需要添加库，即可INCLUDEPATH += /usr/local/includeDEPENDPATH += /usr/local/includemacx: PRE_TARGETDEPS += /usr/local/lib/libopencv*.amacx: LIBS += -L /usr/local/lib/libopencv*开一个控制台测试程序测试之,必要时记得加

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9 到pro里
