Linux compiled OpenCV library [go]

Download source code

Download OpenCV source code from http://sourceforge.net/projects/opencvlibrary, download the file as opencv-1.0.0.tar.gz (if other version, the file name corresponding changes, it is recommended to download the latest version).

Edit

Unzip the file

Tar zxvf opencv-1.0.0.tar.gzcd opencv-1.0.0

If the above output is present, the software required to compile the OPENCV is basically installed and can proceed to the next step. If you are prompted that the required software is not installed, please install and run the./configure command until you are prompted to "now run make ...". Description of some libraries: libjasper-the JasPer JPEG-2000 Runtime Library

Note: Configure files have been omitted from the opencv2.2, can be installed by CMake, reference http://www.samontab.com/web/2010/04/installing-opencv-2-1-in-ubuntu/

Compiling OPENCV

Make

2012-11-14 the current newer opencv2.3.1, installed with CMake, in the centos6.2 system, recommend this document: http://my.oschina.net/douzhenjia/blog/32683. In addition, the current Linux C + + program development, can also be developed as under the VS2008, using the Eclipse CDT, which can be downloaded directly from the Eclipse org website, without the installation directly can run the embedded CDT eclipse. As for Eclipse's OPENCV compilation environment setting, this document is recommended: http://www.cnblogs.com/shihty/archive/2012/10/24/2737552.html. With these 3 things, you'll be happy to start your OPENCV trip!

Installing OPENCV

Execute with Root user

Make install

Edit

Update the Dynamic Connection library

Use the root user to perform the following actions

Add path/usr/local/lib to file/etc/ld.so.conf, and then run the command

Ldconfig

Edit

Test the installation package

To test whether the installation was successful, you can use the following command line to compile the drawing.c example in the source package: (in version 1.0, under directory sample/c)

g++ ' pkg-config opencv--libs--cflags OpenCV ' Drawing.c-o drawing

After successful compilation you should be able to execute ./drawing See the results of the Highgui Output window.
