Following these instructions is recommended for Ubuntu 22.04: ubuntu_2204/README.md
Otherwise to build ros entirely from source without using a PPA (or even the debian ros packages):
git clone [email protected]:lucasw/ros_from_src.git
mkdir build
cd build
# if Ubuntu 20.04
# ROSCONSOLE=https://github.com/ros/rosconsole ../ros_from_src/git_clone.sh
# if Ubuntu 22.04 or later
../ros_from_src/git_clone.sh
# (take look at this script before running as sudo)
sudo ../ros_from_src/dependencies.sh
../ros_from_src/build.sh
The above should be similar to what is in the github action: .github/workflows/ubuntu_20_04.yaml
export ROS_BUILD_DIR=$HOME/own/build/ros_from_src # or whatever
export CMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH:$ROS_BUILD_DIR/ros/lib/cmake
# make this python3.8 if python --version shows that to be your version
export PYTHONPATH=$PYTHONPATH:$ROS_BUILD_DIR/ros/lib/python3.9/site-packages/
# source $ROS_BUILD_DIR/ros/setup.bash
source $ROS_BUILD_DIR/catkin_ws/devel/setup.bash
To build with docker and another ubuntu version:
docker build --build-arg IMAGE=ubuntu:21.10 --build-arg ROSCONSOLE=https://github.com/ros/rosconsole --build-arg PYTHON_MINOR_VERSION=9 . -t ros2110
Build with default Ubuntu 22.04 version:
docker build . -t ros2204
