The messages warn that a version of the library compiled with gcc < 7.1 will not be compatible with a version of the library compiled with gcc >= 7.1. I don't think we need to cover, I don't expect we'll guarantee ABI stability across compiler versions. The reason why I didn't silence the messages for gcc >= 9 is to get informed of future ABI changes, just in case it could be of interest. > > Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> > > --- > > meson.build | 10 ++++++++++ > > 1 file changed, 10 insertions(+) > > > > diff --git a/meson.build b/meson.build > > index 9fc5cc52dc99..718214730da8 100644 > > --- a/meson.build > > +++ b/meson.build > > @@ -69,6 +69,16 @@ if cc.has_argument('-Wno-c99-designator') > > ] > > endif > > > > +# gcc 7.1 introduced processor-specific ABI breakages related to parameter > > +# passing on ARM platforms.
