Developing on Linux (Desktop)

You can develop GRX applications on Linux Desktop. Packages for Ubuntu/Debian are provided by ev3dev.org.

Install

Ubuntu

Only the current Ubuntu (zesty) and Ubuntu LTS (xenial) versions are supported.

sudo apt-add-repository ppa:ev3dev/tools
sudo apt update
sudo apt install libgrx-3.0-dev libgrx-3.0-examples

Debian

Only the current Debian stable (stretch) is supported.

# run as root
wget https://github.com/ev3dev/grx/raw/ev3dev-stretch/.travis/ev3dev-archive-keyring.gpg
mv ev3dev-archive-keyring.gpg /etc/apt/trusted.gpg.d/
echo "deb http://archive.ev3dev.org/debian stretch main" > /etc/apt/sources.list.d/ev3dev.list
apt update
apt install libgrx-3.0-dev libgrx-3.0-examples

IMPORTANT: The GRX3 library package enables bitmap fonts on your system. If you notice that fonts look bad in other programs, this is why. See https://github.com/ev3dev/grx/wiki/Running-Programs#bitmap-fonts.

Run sample programs

These are not installed in $PATH, so you have to use the absolute path.

Example binary files are found in /usr/lib/x86_64-linux-gnu/grx-3.0/examples/. For example:

/usr/lib/x86_64-linux-gnu/grx-3.0/examples/vala/life

Example scripts (text files) are found in /usr/share/doc/grx/examples/. For example:

/usr/share/doc/grx-3.0/examples/python/life.py
