Compile on the Host

Fetch the EEROS scripts on your host and checkout the branch for the host

$ git clone https://github.com/eeros-project/eeros-build-scripts.git eeros-project
$ cd eeros-project
$ git checkout host

Edit the config.sh.in file as follows

use_simulator=true
use_can=false
use_comedi=false
use_ros=false
use_ros2=false

This will build EEROS without the ROS and CAN examples but together with the simulator. If you have ROS2 installed and want to build the ROS examples, change the config.sh.in to

use_simulator=true
use_can=false
use_comedi=false
use_ros=false
use_ros2=true

ros_setup_script=/opt/ros/humble/setup.bash

The last line must point to your ROS installation path. In general this will be /opt/ros/$ros_version_name/setup.bash.

If you want to use ROS1, change the config.sh.in to

use_simulator=true
use_can=false
use_comedi=false
use_ros=true
use_ros2=false

ros_setup_script=/opt/ros/noetic/setup.bash

Further, when using ROS1, search for the line

ros_eeros_git_version=v2.0.1

and change it into

ros_eeros_git_version=v1.0.1

If you want to use EEROS with a CAN bus change the config.sh.in to

use_simulator=false
use_can=true
use_comedi=false
use_ros=false
use_ros2=false

comedi stands for linux control and measurement device interface. It is a collection of drivers for a variety of common data acquisition plug-in boards on the host. If you want to use EEROS with http://www.comedi.org/ you have to install comedi first, see http://www.comedi.org/. Then change the config.sh.in to

use_simulator=true
use_can=false
use_comedi=true
use_ros=false
use_ros2=false

Now you can run the clone script

$ ./clone.sh

After having downloaded the code you can now compile EEROS together with necessary libraries. The build and install directories are set in config.sh.in as follows

install_dir="$wd"/install-x86 
build_dir="$wd"/build-x86

Change this setting if you want to choose different build and install directories.

After this you proceed with

$ ./make.sh

This will put all the executables into the build directory you have chosen and the compiled libraries together with the header files into the install directory. Please keep in mind that build and install directory are both defined in config.sh.in.
