- however, I did 'sudo apt install meson' and seemed to get product meson, (2) when I ran 'meson build' I got
$ meson build
The Meson build system
Version: 0.45.1
Source dir: /home/joachim/iipax/scripts_and_programs/mergetool/gtksourceview/git/gtksourceview
Build dir: /home/joachim/iipax/scripts_and_programs/mergetool/gtksourceview/git/gtksourceview/build
Build type: native build
meson.build:1:0: ERROR: Meson version is 0.45.1 but project requires >= 0.49.0.
But 'sudo apt upgrade meson' tells me I already have the latest meson version:
"meson is already the newest version (0.45.1-2ubuntu0.18.04.1)."
How can I get the required meson version?
