Meson is pure python with a soft dependency on setuptools, and a hard dependency
on either ninja or msbuild (on windows). We do have special dependency handling
or convenience wrappers for a bunch of those tools, but none of them are hard
requirements.

Uh. Meson depends on Python >= 3.5 and optionally on python-setuptools at
runtime. Some of the dependencies there are necessary to run the full test
suite, others I'm not sure what purpose they server.

Nice thing with backports is that they get upgraded when one upgrades 
rest of the distro.


It's probably less of an issue with Python than some other things, but 
having local installs of things that are also available from distro 
itself can cause nasty issues (e.g. forgetting local install of libdrm 
to /usr/local/lib can mean that your desktop fails after you upgrade 
your distro).




Not a solutions for distributions that want to backport newer Mesa etc though.

They were Meson package build deps. Run-time deps are just ninja & python:
https://packages.ubuntu.com/cosmic/meson

My guess is that build configures Meson to the distro, and what's 
available in it.  Dylan?

Those *provide* older Mesa version, so naturally people want to build
latest Mesa on them (especially if they've just bought HW that isn't

require newer Meson version than the one in the distro.

  Unfortunately we can't bump the minimum version at the moment, there
  are a
  couple of LTS distros we need support for that only ship 0.45.x
  currently. As an
  upstream meson dev, we have no time table in place for the removal of

Agreed: if users want a recent version of meson, they might as well
install the current one from pip instead of some slightly less old
version from another distro release :)

> Not a solutions for distributions that want to backport newer Mesa etc though.

I don't really know what these distro's requirements are; can anyone
shed some light on this?

I'd love it if we didn't have to stay this far behind just because some
distro never updates anything.

Indeed :)

Eero, where did you see this "huge amount of esoteric build
dependencies"? I don't really know how to navigate the packages.ubuntu
website to see the actual packaging script, which would have this list.

(I'm looking for something like the "Source Files" link at the top right
of https://www.archlinux.org/packages/extra/x86_64/mesa/ for instance.)

Re: [Mesa-dev] [PATCH 2/2] meson: upgrade minimum meson version

[Ernst Sjöstrand]

For people building newer Mesa pip3 install --user meson is quite a
lot better and more accessible.
Not a solutions for distributions that want to backport newer Mesa etc though.

Those build dependencies look more like runtime dependencies btw,
Meson is just pure python right?

Re: [Mesa-dev] [PATCH 2/2] meson: upgrade minimum meson version

[Eero Tamminen]

Hi,

Got it.


Those *provide* older Mesa version, so naturally people want to build
latest Mesa on them (especially if they've just bought HW that isn't
supported by distro version of Mesa).  Building would fail if Mesa would
require newer Meson version than the one in the distro.


- Eero

PS. On Ubuntu 18.04 LTS, one can install 0.47 Meson binary package
from 18.10, it works fine.  Maybe something similar can be done also
on other LTS distros.

Unfortunately we can't bump the minimum version at the moment, there
are a
couple of LTS distros we need support for that only ship 0.45.x
currently. As an
upstream meson dev, we have no time table in place for the removal of
build_always.

Sorry, I though LTS distros used old versions of mesa.
Got it.
