Hello,
I am trying to install acados on ubuntu 20.04 (I need to work on ros noetic as well), and I am facing issues. The interface I want to install is the Python one. My python version is 3.8.10.
I followed the step by step instructions, but I keep facing issues when running the minimal_example_ocp.py script. See below
(env) fmccastro@francisco:~/acados/examples/acados_python/getting_started$ python minimal_example_ocp.py
Tera template render executable not found, while looking in path:
/home/fmccastro/acados/bin/t_renderer
In order to be able to render the templates, you need to download the tera renderer binaries from:
https://github.com/acados/tera_renderer/releases
Do you wish to set up Tera renderer automatically?
y/N? (press y to download tera or any key for manual installation)

I have already tried to update the LIBC version to a newer one, but I get a segmentation fault message when running minimal_example_ocp.py script again. However, it is more likely there’s an issue with the t_renderer executable. I have also tried to build it from source
as it is mentioned in the , but I dont’ succeed as well.
Thanks in advance
