使用Xcode为OS X Lion / Mountain Lion编译OpenCV (2.3.1+)

Can anyone provide me some detailed guide how to compile OpenCV 2.3.1 on OS X Lion with Xcode?

谁能给我提供一些详细的指南，如何用Xcode编译OS X Lion上的OpenCV 2.3.1 ?

I'm getting mad about this … I got the source, used cmake to create the Xcode template and tried to build it, but it fails with about 200 errors.

我很生气，我得到了源代码，用cmake创建了Xcode模板并尝试构建它，但是它失败了，大约有200个错误。

Thanks in advance, Dom

Detailed guide how to get OpenCV 2.3.1 up and running under OS X Lion (10.7.2) with Xcode 4.2.1 using MacPorts

详细指导如何使用MacPorts在OS X Lion(10.7.2)下运行OpenCV 2.3.1，并运行Xcode 4.2.1。

EDIT 08/06/2012: This is also working for OpenCV 2.4.1. Just make sure you got the latest version of Xcode and installed the "Command Line Tools" (Xcode -> Preferences -> Downloads -> Command Line Tools).

编辑08/06/2012:这也适用于OpenCV 2.4.1。只要确保您得到了最新版本的Xcode并安装了“命令行工具”(Xcode ->首选项->下载->命令行工具)。

EDIT 15/08/2012: Tested everything with Mountain Lion ans the current versions of Xcode & OpenCV … it's working :) And you don't have to use the LLVM compiler.

编辑15/08/2012:在Xcode和OpenCV的当前版本中，使用Mountain Lion测试了所有的东西，并且你不需要使用LLVM编译器。

EDIT 16/10/204: Over the last year I abandoned MacPorts and started using brew, which works better for my purposes.

编辑16/10/204:去年我放弃了MacPorts，开始使用brew，这对我的目的来说更好。

Brew guide

1.) Get the current Version of Brew here.

1)。在这里获取当前版本的Brew。

2.) Make sure brew is ready to us

2)。确保我们准备好了啤酒

brew doctor && brew update 

3.) Install OpenCV (as of 17/20/2014 v2.4.9)

3)。安装OpenCV (17/20/2014 v2.4.9)

brew install opencv

4.) Fire up Xcode (as of 17/20/2014 v6.0.1) and open/create your project

4)。启动Xcode(从17/20/2014 v6.0.1开始)并打开/创建项目

5.) Select your target, go to "General" and hit the "+"-Button in the "Linked Frameworks and Libraries"

5)。选择您的目标，转到“General”并在“链接框架和库”中单击“+”-按钮

5.1.) Click "Add Other", hit "/", go to "/usr/local/lib" and add any libopencv_**.dylib you need

5.1)。点击“添加其他”，点击“/”，进入“/usr/local/lib”，添加任何libopencv_**。dylib你需要

6.) Now add "/usr/local/include" to your "Header Search Paths" under "Build Settings" (target still selected)

6)。现在将"/usr/local/include"添加到"Build Settings"下的"Header Search Paths" (target still selected)

7.) Finally make sure include OpenCV in your .mm files.

7)。最后，确保在.mm文件中包含OpenCV。

MacPorts guide (maybe outdated)

1.) Get the current Version of MacPorts here. Don't forget to add "/opt/local/(s)bin" to your environment PATH

1)。在这里获取MacPorts的当前版本。不要忘记在您的环境路径中添加“/opt/local/(s)bin”

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

2.) Keep your MacPorts up-2-date:

2)。保持你的MacPorts up-2-date:

sudo port -v selfupdate

3.) Install OpenCV 2.3.1 (building with llvm-gcc)

3)。安装OpenCV 2.3.1(带有llvm-gcc的建筑)

sudo port install opencv configure.compiler=llvm-gcc-4.2

4.) Fire up Xcode and create your project

4)。启动Xcode并创建项目

5.) Select your target, go to "Summary" and hit the "+"-Button in the "Linked Frameworks and Libraries"

5)。选择您的目标，进入“Summary”，在“Linked Frameworks和Libraries”点击“+”按钮

5.1.) Click "Add Other", hit "/" and go to "/opt/local/lib"

5.1)。点击“添加其他”，点击“/”，进入“/opt/local/lib”

5.2.) Add any libopencv_**.dylib you need

5.2)。添加任何libopencv_ * *。dylib你需要

6.) Now add "/opt/local/include/" to your "Header Search Paths" under "Build Settings" (target still selected)

6)。现在将"/opt/local/include/"添加到"Build Settings"下的"Header Search Paths" (target still selected)

7.) Finally make sure to have the following lines at the beginning of your .pch file:

7)。最后，确保在.pch文件开头有以下几行:

#ifdef __cplusplus
  #import "opencv2/opencv.hpp"
#endif

Otherwise you'll get some nasty erros like this:

否则你会得到一些像这样讨厌的erros:

"Non-const static data member must be initialized out of line"
"Statement expression not allowed at file scope"

That's it! Hope it helps :)

就是这样!希望它能帮助:)

Thanks to Vachidrewer, I was able to get OpenCv running on Mavericks. I did things in a little different order,so here are my notes.

多亏了Vachidrewer，我才能让OpenCv在小牛上奔跑。我做的顺序有点不同，这是我的笔记。

1. If it isn't installed, install Macports and add it to path. (I already had it installed)

   如果没有安装，请安装Macports并将其添加到path中。(我已经安装了)

2. Use Macports to update itself from the command line $ sudo port -v selfupdate

   使用Macports从命令行$ sudo port -v selfupdate更新自己

3. Use Macports to install opencv and its dependencies from the command line. $ sudo port install opencv

   使用Macports从命令行安装opencv及其依赖项。$ sudo端口安装opencv

4. If it isn't installed, install xCode. (I already had it installed)

   如果没有安装，请安装xCode。(我已经安装了)

5. Use xCode to create a C++ Command line project.

   使用xCode创建一个c++命令行项目。

6. Use xCode to verify that the simple hello world C++ program it created works by running it in the xCode IDE.

   使用xCode来验证这个简单的hello world c++程序，它是通过在xCode IDE中运行它来创建工作的。

7. Modify the main.cpp file created by xCode from the hello world example to the simple opencv example from Vachidrewer.

   修改主。xCode从hello world示例创建的cpp文件到Vachidrewer简单的opencv示例。

8. Notice that xCode editer reports that it can NOT find the header opencv header file.

   注意，xCode编辑器报告它找不到头opencv头文件。

9. Add /opt/local/include/ to the project search path and notice that the editer errors go away.

   添加/opt/local/include/到项目搜索路径，并注意编辑器错误消失。

10. Try to run the program in the xCode IDE and notice that it reports that it can't find the opencv libraries.

    尝试在xCode IDE中运行这个程序，注意它报告说它找不到opencv库。

11. Add a group called opencvfrqmework to the project and add /opt/local/lib/libopencv_core.dylib and /opt/local/lib/livopencv_highgui.dylib to the group.

    在项目中添加一个名为opencvfrqmework的组，并添加/opt/local/lib/libopencv_core。dylib和/ opt /地方/ lib / livopencv_highgui。dylib。

12. Use the xCode IDE to run the project and notice that a window pops up with half od it darker then the other half.

    使用xCode IDE来运行项目，注意窗口会弹出一个窗口，窗口的颜色会比窗口的颜色深一半。

Have you tried just building it using standard UNIX Makefiles?

您是否尝试过使用标准的UNIX makefile构建它?

Follow this guide, and see if that helps. If you have already downloaded the source code, you probably don't need to do the svn checkout that is suggested. You can probably start with Use CMake to build in section 2.

遵循这个指南，看看是否有帮助。如果您已经下载了源代码，那么您可能不需要执行所建议的svn检查。您可以从第2节中使用CMake构建开始。

Hope that helps.

希望有帮助。
