We use Ubuntu 14.04 LTS or 16.04 LTS on the host machine. Other distributions are supported but not documented here. Further, you have to patch the kernel with a realtime patch as described in https://rt.wiki.kernel.org/index.php/Main_Page. It is possible to work without the realtime patch. However, the latency of the system will be much worse and will depend greatly on the load of other programs running on the system.
To use EEROS on the host machine the following packages have to be installed:
$ apt-get install git make cmake g++
Please make sure to use a g++ version of at least 4.8.
If you are not only doing simulations you will have to install further software in order to communicate with your underlying hardware. This could be libraries supporting EtherCAT, CANOpen, comedi or flink. In addition to one of this libraries you need the appropriate eeros wrapper library.
Setting up the correct way of compiling EEROS can be quite cumbersome. We strongly recommend to use our scripts. What to you want to do with EEROS?
Create a new and empty directory and download the scripts from
$ git clone https://github.com/eeros-project/eeros-build-scripts.git
config.sh.infile. Choose an appropriate toolchain file. The toolchain file basically determines which compiler you are going to use. If you work on the host and want to use the standard compiler you can omit this toolchain file. See Toolchain File for ARM Platform for an example of a toolchain file.
Now you can run the
After this you can continue with Compile EEROS.
Clone the eeros source repository:
$ git clone https://github.com/eeros-project/eeros-framework.git
Checkout a stable version of EEROS:
$ cd eeros-framework $ git checkout v0.5
In addition to the eeros library you need to install libraries for hardware access together with the appropriate eeros wrapper libraries, see Installing Hardware Libraries.
