Full Process of OpenCV2.3.0 installation and configuration compilation under Ubuntu12.04

After several days of efforts, we have initially completed the installation and use of opencv2.3.0. Record the process to help others. First of all, the step is to download and compile opencv. According to the idea provided by this great god, it is easier to install and compile opencv. The main steps are as follows: 1. Download opencv decompress opencv2, enter the decompressed directory, create a directory for storing the compiled file, and retrieve the directory name by yourself, my name is release3. I don't remember which version of opencv will be used after compilation.

After several days of efforts, we have initially completed the installation and use of opencv2.3.0. Record the process to help others.

First of all, the step is to download and compile opencv. According to the idea provided by this great god, it is easier to install and compile opencv. The main steps are as follows:

1. Download opencv and decompress opencv

2. Enter the decompressed directory and create a directory for storing the compiled files. The directory name is obtained by yourself. The name I used is release.

3. Do not remember which version of opencv is used, and the pre-compilation configuration will no longer use the configure file. Instead, use cmake to check whether cmake is installed in your system.

4. Go to the directory we just created and run cmake

5. make & make install.

It is particularly prompted that you need to install a library, or you will find a problem during running.

OpenCV Error: Unspecified error (The function is not implemented. rebuild the library with Windows, GTK + 2.x or Carbon support. if you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file/home/bush/OpencvSrc/OpenCV-2.3.0/modules/highgui/src/window. cpp, line 275

Terminate called after throwing an instance of 'cv: exception'

What ():/home/bush/OpencvSrc/OpenCV-2.3.0/modules/highgui/src/window. cpp: 275: error: (-2) The function is not implemented. rebuild the library with Windows, GTK + 2.x or Carbon support. if you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvNamedWindow

The cause information of the problem has prompted you to install libgtk2.0-dev and pkg-config. It is not difficult to enter the following command. Pkg-config has been installed in the system.

The command corresponding to the above steps is

1,
Wget http://nchc.dl.sourceforge.net/project/opencvlibrary/opencv-unix/2.3/OpenCV-2.3.0.tar.bz2

Tar-xvf OpenCV-2.3.0.tar.bz2

2,

Cd OpenCV-2.3.0
Sudo mkdir relese
Cd relese
Sudo apt-get install libgtk2.0-dev

3. Check whether cmake is installed in your system. If not, install the command on your own.

Sudo apt-get install cmake

I usually write the installation and compilation processes in the script,
