OpenCV学习——各个环境的装配总结(汇总)

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;

}
