Sorry, I was replying form mobile last night,

  if (dep_xcb_dri3.version().version_compare('>= 1.13') and
  dep_xcb_present.version().version_compare('>= 1.13'))

will work. Meson's recursive descent parser sometimes leaves something to be
desired.

 I'm a bit unsure about the xcb-present version dependency, as that was
 added in a different commit.  OTOH I guess Dave is building vulkan with
 his patch so it is perhaps not a built-time dependency.

hmm, annoyingly enough I found that on rawhide (meson 0.45.0), I seem

ahh, yeah, and I guess that will get rid of the confusing error msg
about xcb-dri3 1.13 not found..


>
> Or should we be checking for xcb_dri3 and xcb_present >= 1.13?

I'm not entirely sure why we were checking for xcb-present >= 1.13..
if that is actually a build time requirement then I think Dave's
initial patch needs some more ifdef..  (but otoh, if it was, I guess
he would have noticed.)

Anyways, I did a build w/ anv+radv enabled with xcb-present == 1.12
(and xcb-dri3 1.12).. and 61309c2a727d52d543207d6ae79fcb3e68b5cff3
looks like it just cares about >= 1.12 of both of those (although not
sure if it is a compile time dependency).

So *possibly* for both meson and autotools we should require 1.12, and
optionally 1.13 for HAVE_DRI3_MODIFIERS?

I think you could simplify this by doing:

 if dep_xcb_dri3.version().version_compare('>= 1.13')

Or should we be checking for xcb_dri3 and xcb_present >= 1.13?
