Installing from Source Under Ubuntu¶
This page explains how to install the libavg developer version from github on an Ubuntu machine. If you run into any issues, have a look at Known Linux Installation Issues.
Prerequisite Packages¶
Start with the installation of all needed packages:
$ sudo apt-get install git cmake libxml2-dev \
libpango1.0-dev librsvg2-dev libgdk-pixbuf2.0-dev libavcodec-dev libavformat-dev \
libswscale-dev libavresample-dev python-dev libboost-python-dev libboost-thread-dev g++ libsdl2-dev \
libxxf86vm-dev libdc1394-22-dev libjpeg-dev linux-libc-dev libvdpau-dev
To support native linux Multitouch devices, you also need to install libxi-dev.
Checkout and Build¶
Check the code out from git:
$ git clone https://github.com/libavg/libavg.git
Afterward, type:
$ cd libavg
$ mkdir build
$ cd build
$ cmake ..
Start compilation with:
$ make -j3
-j3 is the number of parallel compile processes you'd like to run. A good heuristic is to set this to the number of cores you have + 1.
Then do a make install to get libavg installed in the PREFIX path, which is /usr/local by default:
$ sudo make install
To install libavg into a virtualenv, make sure it is active during the cmake step.
Test¶
libavg provides some tests which can be used to check if everything works:
$ make check
Report any test failures in the forums :-).
