Download and installThis guide is intended to help in the installation and configuration of the QVision on a new system. It also includes instructions to get a first "hands-on", not so simple "kind-of-hello-world" QVision sample application running.Dependencies of the QVisionThe QVision needs the following libraries to be installed:
Optional libraries and back-end applicationsQVision can be compiled with functionallity to interoperate with the following libraries and applications. Install them before configuring and compiling the QVision if you are planning to use them from the QVision:
Setting up at Ubuntu systemsIf you are planning to install QVision on a Ubuntu, Debian or any other distribution with a similar package management, you can directly install the following packages:
For the optional libraries (OpenCV, CGAL), you can install the following packages:
Using apt-get, these packages can be installed from the command line with the following commands:
DownloadThe latest release and older versions can be downloaded from the following url:http://forja.rediris.es/frs/?group_id=321 Compilation and Install.Once you have the tar file for QVision, named QVision.<version>.tgz, copy it to your home directory (or a temporary location for compiling), and untar-it using this line:
# tar xzvf QVision.<version>.tgz Then you should rename or copy the file config.pri.example inside the QVision directory to config.pri. This file contains several configuration variables which can be modified to tune the compilation and installation of the library. Also, you can activate QVision interoperativity with other libraries, such as OpenCV and CGAL in this file. You can find detailed information about these configuration parameters in the own file config.pri. Once customized the config.pri file to your needs and system, compile the library using the following commands inside the QVision directory:
# qmake # make This will compile the library. When compilation is done, you should install it in your system. This will copy some files in the directory specified in the variable 'INSTALL_PATH'. If that route is in your home directory, or other place you have permissions to write, you should simply do the following:
# make install Otherwise, you should use sudo console command, to copy the files as a super-user:
# sudo make install If you need to uninstall the library, simply compile again, and use the following line:
# sudo make uninstall This will erase QVision's library files from the directory where you installed it previously. |
