"Sandbox violation" with meson 0.57

[jeromekelleher]

Looks like our C library build is broken by meson 0.57. The recommended approach for now is to make sure you have an older version installed:

python3 -m pip install meson==0.56

It doesn't seem like meson is in the requirements/development.txt file. Perhaps it should be, pinned to the working version? I just dumbly installed meson, it failed of course, but then it took me a while to remember that I'd seen this issue in my inbox some months ago.

[jeromekelleher]

Hmm yes, probably should be. I think it's a fairly harmless dependency right, it doesn't pull in loads of other stuff? (That's probably why I left it out originally)

[grahamgower]

Zero dependencies. One must install ninja manually too!

Meson is at 1.0.1 now, so assuming this has been sorted.
