Configuring and building sources

Run the following commands:

mkdir build
cd build
cmake ..
make -j4

NOTE: If you want to build a .deb or .rpm package for this software, instead of the provided cmake command, you should use:

cmake -DCMAKE_INSTALL_PREFIX=/usr ..

to install package files in /usr instead of /usr/local.

If some requirements are not fullfilled, CMake will inform you about it and you will have to install the missing software before continuing.

You can now generate a package (.deb or .rpm depending what system you are in).

For generating a package you can run

fakeroot make package

Then you'll get something like veyon_x.y.z_arch.deb or veyon-x.y.z.arch.rpm

Alternatively you can install the built binaries directly (not recommended for production systems) by running the following command as root:

make install

Arch linux

A PKGBUILD can be found in the AUR.

PPA

This PPA contains official Veyon packages for Ubuntu suitable for use both on desktop computers and ARM boards (e.g. Raspberry Pi). Even though only packages for LTS releases are available they should work for subsequent non-LTS releases as well.

sudo add-apt-repository ppa:veyon/stable
sudo apt-get update

openSUSE

Veyon is available on official openSUSE Tumbleweed repository.

sudo zypper in veyon

For openSUSE Leap 15.2, use the unofficial package from Education repository.
