This installation guide is specifically designed to enable individuals and researchers to get up and running with F´ quickly. This guide is not intended for large teams with specific content management (CM) requirements.
Note: see the troubleshooting section at the bottom for help resolving common issues found during F´ installs.
F´ depends on several items before the user should attempt to install it. These requirements are listed below and should be on any system the user wishes to use. Should these items not be available on the user’s Operating System, then a Virtual Machine should be used. One option is VirtualBox.
- Linux or Mac OS X operating system (or Windows Subsystem for Linux on Windows)
- CMake 3.5 or newer. CLI tool must be available on the system path.
- Bash or Bash compatible shell
- CLang or GCC compiler
- Python 3.6+ and PIP
- Python Virtual Environment * (pip install venv or pip install virtualenv)
You can install them using this one-liner command :
sudo apt-get update && sudo apt-get -y install cmake git python3-pip (for Debian based OS’es)
yum install cmake git python3-pip (for RHEL OS)
Note: it is possible to install and run F´ without a virtual environment, however; for individuals and researchers, this is the recommended approach.
Create and Activate a new Python Environment
This will create a new virtual environment for F´ to be installed into. The following commands
will create a new virtual environment called
fprime-venv and ensure that the virtual environment
python3 -m venv ./fprime-venv . ./fprime-venv/bin/activate
Any time the user wishes to use F´, this virtual environment should be activated. This should be done in each new shell the user uses. This is all that is required to activate F´ for use.
Note: file system for VirtualEnvironment should support symbolic links, or use the
--always-copy flag to pip.
Activate the Virtual Environment
Cloning the F´ Repository
Installation of F´ requires cloning of the F´ core repository. This uses Git. This will bring down the core framework and C++ files.
git clone https://github.com/nasa/fprime
Installing F´ Python Requirements
F´ python-support packages have certain requirements on various Python packages available on PYPI. These requirements are broken out into two files one for the Autocoder tools and one for the GDS tools package. This is to enable users to choose which tools they’d like to use.
Installing F´ Python Packages
pip install --upgrade fprime-tools fprime-gds
Checking Your F´ Installation
The user may easily checkout that their F´ installation has succeeded by testing the following commands. First, the user will test the build and Autocoder install. Next, the user will test the GDS layer components. Should the user not have installed the given component, the commands won’t work.
Testing F´ Autocoder Installation Via Building Ref Application
cd Ref fprime-util generate fprime-util build --jobs "$(nproc || printf '%s\n' 1)"
Testing F´ GDS Installation Via Running HTML GUI
fprime-gds -g html -r <path to fprime checkout>/Ref/build-artifacts
Ref should contain pre-built dictionaries and binaries for the user’s system. This can
be achieved by running the Autocoder installation test (the user must have a working Autocoder
(Optional) Installing Tab Completion
Several of F´s command-line utilities support tab completion. To enable these tools to use it, see the instructions here.
This section will add some known hints to trouble-shooting with the installation of F´. This will hopefully help users install things more effectively.
Ubuntu, Debian, Python PIP, and Python Virtual Environments
Ubuntu and possibly other Debian variants don’t include the virtual environment nor pip packages in the default python 3 installation. To get a fully functional Python 3 installation, use these commands on Ubuntu:
sudo apt install python3 python3-pip python3-venv
Now you should be able to run the installation without trouble.
Mac OS X and CMake Command Not Found
If the user chooses to install CMake directly from the CMake site (not using homebrew nor Mac Ports), then the CMake command-line tools must be added to the user’s PATH or default system libraries. The quickest command to do that is:
sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install

System Python, Packages, and Python3
Many operating systems offer python PIP packages through their package manager (apt, yum, etc). Most python projects recommend avoiding those packages, but rather installing from PIP in a virtual environment. The reason for this is that the version of the python package from the OS may not be the required version that the python project depends on. Thus, for F´ we strongly recommend using a virtual environment and not system packages.
If the user chooses to use system python as their python to run F´, they must ensure that “python” available on the path points to a Python3 install, not the Python 2 installation that most OSes default to. Also, packages F´ uses when installing may break the system Python, and prevent the OS from functioning. Use at your own risk.
