Any ideas what should I install also?

Output seems normal, with a few key points (1).

It should have opened a web browser with the visualizer, after displaying the last couple lines of output. If it did not open the browser, I will have to look into it and ask that you share some details about your environment.

• Running with or without Docker?
• Which version of Python?

(1) About the error messages.

WARNING:haros.extractor:C++ AST parser not found.

Expected. Only needed if you want to extract models from source code. Requires libclang in your system and clang in Python, both with equal versions. More details:

WARNING:haros.analysis_manager:Could not import pyflwor. Skipping query execution.

Expected. Only needed if you want to write/run queries over extracted models. More details:

ERROR:haros.analysis_manager:Plugin haros_plugin_cccc ran into an error. ERROR:haros.analysis_manager:Plugin haros_plugin_cppcheck ran into an error.

Probably missing the corresponding tools. The HAROS plugins for these are just wrappers that call the tools cccc and cppcheck respectively.

[sudo] apt-get install cppcheck
[sudo] apt-get install cccc

CCCC is used for metrics, such as complexity and coupling, in C++ code.

CppCheck detects bugs, undefined behaviour and dangerous coding constructs in C++ code.
