Have you read the docs on how to build FC? If you're building from source, you probably need several more flags. Please report to the forum first.

I have installed compile tools for Ubuntu at the link: https://wiki.freecadweb.org/CompileOnUnix

The compile step was successful, but I can not start FC.

Just to add another data point. Ubuntu 20.04

I get this error. I have all the deps, etc. (this particular PC has been building 0.20 for several weeks, daily, with no issues, and still does build without errors)

But, after an install of Pyside2 dev tools to get the uic to python converter, FC throws this error when started from the terminal.
I have attempted to remove the pyside tools and re-install all deps and FC source. And FC still builds without error, but tosses this error when launched.

I finally got a working FC after a read of this forum thread: forum thread

I had to:

uninstall 
pip uninstall PySide2 shiboken2

At this point FC would start but still couldn't find a couple differe UI init files

During initialization the error "UI file does not exist" occurred in /home/mac/freecad-build/Mod/Arch/InitGui.py
Please look into the log file for further information

(

Then I used apt to reinstall all the prescribed FC deps. And rebuilt FC.

It now appears to be fixed.

I'm good at this point.

What about the OP?

@drmacro is it worth notating https://wiki.freecadweb.org/CompileOnUnix ?
