[RFC PATCH v2 0/8] Automatically convert configure options to meson buil

From: Paolo Bonzini
Subject: [RFC PATCH v2 0/8] Automatically convert configure options to meson build options
Date: Thu, 7 Jan 2021 15:00:31 +0100

This is v2 of a concept that was first posted last September.  In the
meanwhile more options have been added to Meson, so the effect of the
change can hopefully be evaluated more accurately.  At least, the amount
of lines removed in the configure script is larger than the size of
the script itself!

Regarding the code itself, the main change is that the script has been
rewritten from Python to Perl.  The reasons for this are detailed in
the commit message.

For the parsing of an option to be completely automatic, there must be
no mentions of the corresponding variable in configure.  Patches 1 to
6 clean up some of the stragglers to enable more automatic conversions.
The only remaining options to be split between configure and Meson are
capstone, git, slirp, default_devices, cfi and xen.


Paolo Bonzini (8):
  build-system: clean up TCG/TCI configury
  cocoa: do not enable coreaudio automatically
  gtk: remove CONFIG_GTK_GL
  configure: move X11 detection to Meson
  configure: move GTK+ detection to Meson
  configure: move Cocoa incompatibility checks to Meson
  configure: quote command line arguments in config.status
  configure: automatically parse command line for meson -D options
