如何在OSX中使用QT设置OpenCV？ [英] How do you set up OpenCV with QT in OSX?

问题描述

我想使用新的C ++ OpenCV接口在OS X Snow Leopard的Qt Creator中创建Qt应用程序。我如何做到这一点？这个很好的解释很难在网上。

解决方案

我实际上做到了，这是相当容易。您可以从qt网站下载QtSDK作为一个dmg，安装只是点击和播放。

之后，我使用MacPorts，MacPorts是一个包管理（如aptitude，portage，pacman等）为osx。 http://www.macports.org/ ，下载并再次：点击即播。 / p>

要使用MacPorts，首先需要使用make和gcc / g ++等工具。这些包括在包xcode（它在苹果商店）。当然，这些工具与开发人员的cpu一样重要。

安装xcode后，make / g ++ / gcc就在您的系统上，但它们不在您的路径中。在终端中，命令不会存在。要解决这个问题，打开xcode ide（如果我允许将其称为ide，我是？）。然后转到XCode（左键屏幕） - >首选项 - >下载。在那里你可以安装命令行工具，这样做。

然后make应该在那里。使用终端进行验证。只是键入make可能会消息你'make： * 没有指定目标，没有找到makefile。

然后，要安装opencv，我安装了MacPorts，输入sudo port install opencv，等待一会儿，如果所有去了，你应该有opencv。它安装在/ opt / local中。因此，您可能需要将这些添加到您的.pro文件中：

  CONFIG + = MYHOTOSXMACHINE 
 
 MYHOTOSXMACHINE {
 INCLUDEPATH + = / opt / local / include / 
 LIBS + = -L / opt / local / lib / 
} 
  pre> 
 
 
所以，你去。好运！
 
 
 
 PS：我不是新的整个linux / gnu / posix的东西，但我是新的osx。因此，如果有一个更干净的方法来做到这一点，随时评论。
 
I want to use the new C++ OpenCV interface to create Qt applications in Qt Creator on OS X Snow Leopard.  How can I do this?  Good explanations of this are very hard to come by online.
解决方案
I actually did this, and it was fairly easy. You can download QtSDK from the qt-website as a dmg, installing that is just click-and-play.

After this I used MacPorts, MacPorts is a package-manager (like aptitude, portage, pacman, etc) for osx. http://www.macports.org/, download it, and again: click-and-play.

To use MacPorts, you first need tools like make and gcc/g++ to work. These are included in the package xcode (which is in the apple store). Of course, these tools are as important as a cpu to a developer. You would want them in the first place.

After installing xcode, make/g++/gcc are on your system, yet they are not in your path. In a terminal, the commands won't exist. To fix this, open the xcode ide (If I am allowed to call it an ide, am I?). Then goto XCode (lop left screen)-> Preferences -> Downloads. There you can install the 'Command Line Tools', do this.

Then make should be there. Use a terminal to verify. Just typing make will probably message you 'make: * No targets specified and no makefile found.  Stop.', but not 'command not found'.

Then, to install opencv I installed MacPorts, type 'sudo port install opencv', wait a while and if all went well, you should have opencv. It is installed in /opt/local. Therefore you might need to add these to your .pro-file:
CONFIG += MYHOTOSXMACHINE

MYHOTOSXMACHINE {
    INCLUDEPATH += /opt/local/include/
    LIBS += -L/opt/local/lib/
}
So, there you go. Good luck!

PS: I not new to the whole linux/gnu/posix thing, yet I am new to osx. So if there is a cleaner way to do this, feel free to comment.
