[dg0yt]

You need a more recent python3 for any port which builds with meson.
The python3 from port python is good enough.

[dg0yt]

You need a more recent python3 for any port which builds with meson.

This should really be checked as part of the meson build scripts in vcpkg.

[soroshsabz]

I have default bionic python, and I think vcpkg must be work with official live ubuntu LTS

ssoroosh@bionic:~/vcpkg$ python3 --version
Python 3.6.9

[dg0yt]

Ubuntu 18.04 is five years old, so there were at least two more recent LTS release.... (Written on an 18.04 installation.)

[soroshsabz]

@dg0yt But it is still live and official supported.

[dg0yt]

i.e. Ubuntu gives certain promises. Obviously, these don't include offering new versions of python. Ubuntu 18.04 also lacks modern compilers.

[soroshsabz]

@dg0yt Ok, I say vcpkg must use python version that support on bionic. (or download itself like cmake)
