Hi gstreamer team,

I followed https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-meson.html?gi-language=c to build source from gstreamer master using meson. I'm running Ubuntu 20.04 as the OS. When I run "meson build_directory/" for the initial configuration, I got an error message on python3. I searched around and could not find a solution. Any idea how to solve this issue?

Thanks,

Sounds like you need to install the setuptools python package for ubuntu 20.04.

A quick google says that the package is python3-setuptools for ubuntu 20.04: https://packages.ubuntu.com/focal/python3-setuptools.

Cheers

Thanks Matthew, it works! There're more missing packages discovered when it moves on, here is the list of packages I've added (after OS installation) to make meson complete its job. "sudo apt-get install –y git meson build-essential clang python3-setuptools libmount-dev flex bison". In case anyone like me is first time to build the source from gstreamer on Ubuntu, they can install these packages in the beginning to avoid hiccup. Thanks again for your help.
