How to compile CentOS OpenCV under Linux? (OS) (Linux) (CentOS) (Image Processing) (C/C++)

Abstract

CentOS OpenCV is a C/C++ open source Computer Vision shared library, as long as it is installed directly on Windows, but it needs to be compiled manually on Linux. This article is my compilation experience in CentOS 5.1.

Introduction

Step 1：

Go to SourceForge.net : Open Computer Vision Library and download opencv-1.0.0.tar.gz for Linux.

Step 2：

Unpack opencv-1.0.0.tar.gz

[root@localhost ~]# tar -zxvf opencv-1.0.0.tar.gz

Step 3：

Go to opencv directory

[root@localhost ~]# cd opencv-1.0.0

Step 4：

Detect the operating environment and configure OpenCV to be installed in/usr/local/opencv

[root@localhost opencv-1.0.0]# ./ configure --prefix=/usr/local/opencv

Step 5：

Compile CentOS OpenCV

[root@localhost opencv-1.0.0]# make

Step 6：

Install CentOS OpenCV

[root@localhost opencv-1.0.0]# make install

Step 7：

Update Dynamic Link Library

[root@localhost opencv-1.0.0]# vi /etc/ld.so.conf

join

include ld.so.conf.d/*.conf

/usr/local/opencv/lib

Archived and executed

[root@localhost opencv-1.0.0]# ldconfig

Step 8：

Testing CentOS OpenCV for successful installation

[root@localhost opencv-1.0.0]# cd samples/c

[root@localhost c]# gcc -I/usr/local/opencv/include/opencv -L/usr/local/opencv/lib -lhighgui -lstdc++ drawing.c -o drawing

[root@localhost c]# ./ drawing

execution result
