Oh, wow, total showstopper. I hadn't even thought about the libtool
objects. Now I'm seeing exactly what you're seeing. This is really a
difficult problem to attack because, with the existing setup, the Mesa
sources need to be know at dist time and at configure time. And that's
really no different than hardcoding the _la_SOURCES in the xserver
Makefile.am's that's happening now.
Here's another ugly fix that might improve the situation slightly. At
least people would have a defined path forward if their Mesa sources
aren't the same as the developer's Mesa sources. The path to Mesa is
given to autogen.sh. This goes through and creates a static list of
the Mesa sources from the "sources" files in Mesa. Then automake runs
with these static lists included and can generate the
At configure time, the Mesa tree is pointed to again and the symlink
script is run. Assuming that the Mesa tree at dist and at configure
are different (say a file changed names), make is going to bomb. Then
you could at least just run autogen.sh again pointing to your Mesa
tree, the _la_SOURCES would be updated to what's in your tree, and
hopefully things would work. There could maybe even be a sanity check
at configure time that compares the names of the Mesa sources from
your tree vs. what has distributed.
This might be a complete dead end.
