With autoconf packages, we often specify ac_cv_func_... cached values to
avoid runtime checks during configure. With meson the equivalent is
setting properties in cross-compilation.conf which we cannot do in
Buildroot at the moment.
For example, libglib2 used to set ac_cv_func_printf_unix98 and
ac_cv_func_vsnprintf_c99 so that the system printf could be used, but
with the conversion to meson these checks fail and the gnulib fallback
is used.
Add infrastructure in the same way as FOO_MESON_EXTRA_BINARIES to allow
per-package modification to the cross-compilation properties.

# Meson package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for Meson packages. It should be used for all
|
|
# packages that use Meson as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this Meson infrastructure requires
|
|
# the .mk file to only specify metadata information about the
|
|
# package: name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default Meson behaviour. The
|
|
# package can also define some post operation hooks.
|
|
#
