Hi to all,
I'm currently building Mesa,but the xorg state-tracker is
broken.From having the error messages I got from where the build stopped,I
looked into the problem and discovered these patches that could potentially
fix my problem.
I wish to know if they are going to be committed to the Mesa master git
branch?.Alternatively,is there is a way of using git to get the patches,or
can I copy the separate pieces of code and save them as diffs and apply them
that way?I was wondering if I do the latter,will it affect the Mesa git code
the next time I do a git pull and they get committed after I applied the
patches?
Regards,
STEVE555
