how do I build xf86-video-ati

Thanks Michel,

Yes indeed,   but I was using jhbuild and it seems it already installed those xorg-macros in file path 
xorg-build/share/aclocal/xorg-macros.m4
with version 1.19

but perhaps that is not the place where  xf86-video-ati expects to find it?

By the way,  a very similar problem occurs on a debian sid/buster distro :
*** Configuring xf86-video-ati *** [139/201]
/data/xorg_180615/xorg/driver/xf86-video-ati/autogen.sh --prefix /data/xorg_180615/xorg-build --disable-Werror  --without-xmlto --without-fop --without-xsltproc

autoreconf: aclocal failed with exit status: 1

I do not exactly know what kind of a "thing" xorg-macros is  --  apparently it is not a regular xorg package as at least it does not appear in https://cgit.freedesktop.org/xorg/ 
I guess it is just the one file?    How would it be brought into a build if not using jhbuild?

Anyway,   can you suggest  what I should do?

Cheers,    John
