Hello

I am trying to run through the academy training and I get this error message when I try building the "network_terminal_CC3220SF_LAUNCHXL_tirtos_ccs" project:

gmake: Target 'all' not remade because of errors.

I guess I have some errors in my configuration, though I followed the instructions from the installation webpage. I am running Ubuntu 18.04. Are there libraries that I am missing?

Thanks for your help.
