Building NVDA from source

[paulber19]

Steps to reproduce:

Hi.
By following the instructions in the readme.md file of the cloned NVDA repository, I managed to launch NVDA from source.
I also managed to create the NVDA installation file with the "scons.bat launcher" command, but there are warnings that I don't understand.
The first warning is:
F:\Developpement\nvda.venv\lib\site-packages\setuptools\dist.py:472: UserWarning: The version specified ('source-master-187f8d2') is an invalid version, this may not work as expected with newer versions of setuptools, pip, and PyPI. Please see PEP 440 for more details.

Is there anything to do?

The second that I interpret as a warning because of the question marks is:

Same question: is there something to do?

Actual behavior:

Finally, I tested the "scons.bat dist" command to create the equivalent of a portable nvda (at least that's what I understood).
His execution went well, apart from the same warnings. But there is no "nvda.exe" file to launch NVDA.
Is this normal?

Expected behavior:

Be able to launch NVDA when building with "dist" option

Does the issue still occur after restarting your computer?

Have you tried any other versions of NVDA? If so, please report their behaviors.

If NVDA add-ons are disabled, is your problem still occurring?
