Hi again:
I sorry to be such a pain but, here are two more problems with the
last patch file called: "avarice-2.10_atxmega256a3_support.patch".
Problem #1:
All the file names in this patch are prefixed by "+++
avarice-2.10_patched/src/xxxx".
The only way to get this patch to work is by removing all the "+++
avarice-2.10_patched/" from the file names. Is there another way to
get "patch" to understand that the
sub-directory is not "+++ avarice-2.10_patched" but "+++
avarice-2.10".
Problem #2:
When I did fix the above problem the patches apply OK but the make
fails with a strange error:
devdescr.cc:4799: error: brace-enclosed initializer used to
initialize ‘unsigned int’
devdescr.cc:4799: error: brace-enclosed initializer used to
initialize ‘dev_flags’
make[2]: *** [devdescr.o] Error 1
make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1
The problem seems to be this large chunk of code being added:

It seems that somewhere in this mess is an extra curly brace, or one
missing and I don't understand this file format so I cannot discern
where exactly the problem lies.
If I remove this chunk of code all the patches apply fine and Avarice
builds to completing without any errors.
However, I don't know if it works as I haven't actually used it for
anything yet.
Perhaps tomorrow I'll get to it.
TIA,
Ed
