本文详细介绍了如何在Windows环境下安装并配置OpenCV，包括使用MS Visual C++和MinGW进行配置的方法。此外，还提供了Linux和Mac OS X系统的安装步骤。

Windows

MS Visual C++

Install OpenCV

Download OpenCV installer and install it. I assume you have installed onto C:/Program Files/OpenCV.

Setup MS Visual C++

I write details based on MS Visual Studio 2005. Follow menus of MS Visual C++ window as:

Tools > Options > Projects and Solutions > VC++ directories >

Show Directory for: > Include Files. Now add

C:/Program Files/OpenCV/cv/include

C:/Program Files/OpenCV/cvaux/include

C:/Program Files/OpenCV/cxcore/include

C:/Program Files/OpenCV/otherlibs/highgui

C:/Program Files/OpenCV/ml/include

C:/Program Files/OpenCV/otherlibs/cvcam/include

Show Directory for: > Library Files. Now add
```
C:/Program Files/OpenCV/lib
```

(Option) Show Directory for: > Source Files. Now add

C:/Program Files/OpenCV/cv/src

C:/Program Files/OpenCV/cvaux/src

C:/Program Files/OpenCV/cxcore/src

C:/Program Files/OpenCV/otherlibs/highgui

C:/Program Files/OpenCV/otherlibs/cvcam/src/windows

Setup MS Visual C++ for each project

Right Click Project > Property >
Configuration Proeperties > Linker > Input > Additional Dependencies. Now add
- cv.lib cxcore.lib cvaux.lib highgui.lib ml.lib cvcam.lib
Change 'Configuration' drop down menu from Release (Debug) to Debug (Release).
Do the same thing (Add .libs to Input)

Or, add below codes into your source codes above #include(s).

#ifdef _MSC_VER

#pragma comment(lib, "cv.lib")

#pragma comment(lib, "cxcore.lib")

#pragma comment(lib, "cvaux.lib")

#pragma comment(lib, "highgui.lib")

#pragma comment(lib, "ml.lib")

#pragma comment(lib, "cvcam.lib")

#endif

MinGW gcc/g++

Install MinGW

MinGWis a collection of freely available and freely distributable Windowsspecific header files and import libraries, augmenting the GNU CompilerCollection, (GCC), and its associated tools, (GNU binutils). MinGWprovides a complete Open Source programming tool set which is suitablefor the development of native Windows programs that do not depend onany 3rd-party C runtime DLLs.

Download Automated MinGW Installer from MinGW project page and install.
Install gcc and g77
Assume MinGW is installed on C:/MinGW

MinGW originally does not include gdb debugger. If you want it, download .tar.bz2 of GNU Source-Level Debugger from MinGW project page and unarchive it.
Copy files into C:/MinGW

How To Compile

g++ test.cpp -I"C:/Program Files/OpenCV/cv/include" -I"C:/Program Files/OpenCV/cxcore/include" -I"C:/Program Files/OpenCV/otherlibs/highgui" -L"C:/Program Files/OpenCV/lib" -lcxcore -lcv -lhighgui -lcvaux -lml

How to Use MinGW on cygwin

Cygwinis a Linux-like environment for Windows. It consists of two parts: ADLL (cygwin1.dll) which acts as a Linux API emulation layer providingsubstantial Linux API functionality. A collection of tools whichprovide Linux look and feel.

http://www.cygwin.com/

Setup to use MinGW g++ instead of cygwin g++

$ export PATH=/cygdrive/c/MinGW/bin:$PATH

Linux

gcc/g++

Download OpenCV source codes (.tar.gz)

Root user

tar zxvf opencv-1.0.0.tar.gz; cd opencv-1.0.0

./configure

make

make install

General user

tar zxvf opencv-1.0.0.tar.gz; cd opencv-1.0.0

./configure --prefix=$HOME/usr

make

make install

# configuration

export PATH=$HOME/usr/bin/:$PATH

export LD_LIBRARY_PATH=$HOME/usr/lib:$LD_LIBRARY_PATH

export PKG_CONFIG_PATH=$HOME/usr/lib/pkgconfig:$PKG_CONFIG_PATH

export MANPATH=$HOME/usr/man:$MANPATH

Compilation is as

g++ `pkg-config --cflags opencv` foo.c -o foo `pkg-config --libs opencv`

It must be equivalent with

g++ -I$HOME/usr/include/opencv foo.c -o foo -L$HOME/usr/lib -lcxcore -lcv -lhighgui -lcvaux -lml

where $HOME/usr is the prefix specified at the ./configure step.

MacOS X

I tried long time ago, there should exist easier ways nowadays.

Install Xcode from OS CD, 'custome' to install everything.
Get OpenCV and http://lestang.org/article45.html.
Copy these files into OpenCV.
./configure to create cvconfig.h.
Double click Xcode project in _make, add path of the cvconfig.h to highgui.
Build, try projects of samples.
Toexecute builded program on command line, copy_make/build/Debug/*.framework into ~/Library/Frameworks. If Frameworksdoes not exist, create it.
```
$ _make/build/Debug/kmeans.app/Contents/MacOS/kmeans
```

Sample Test code

#include 

#include 

#include 

#include 

#include 



int main(int argc, char *argv[])

{

 // Nothing but create a window

 cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);

 cvMoveWindow("mainWin", 100, 100);

 cvWaitKey(0);

 return 0;

}
