Vasily, All,

Oh, actually speaking, I simply didn't know about these files.  Errr... I
strongly believe that this worth to be mentioned in the BUILD.txt file.

With the new knowledge, I was able to install some packages (such as
texinfo and libtool, that appear to be build-deps for some of the Owl
packages) into my Raspberry, and this allowed me to proceed a little
further.  I'm still playing with installing more previously-failed build
dependencies; Raspberry Pi is *S*L*O*W* so I'm still unable to give a
result summary :)

However, another problem appeared which perhaps I'm unable to fix myself.
Some Owl patches failed to apply:

# root@...pi /usr/src/world/logs# grep ^Hunk * | grep FAILED
# acct:Hunk #1 FAILED at 5.

# patch 2.6.1

[...]

I'm attaching a file with more verbose log excerpts, that include the patch
numbers.  Could someone please look into this?  This is a bit surprising
for me, as I'm used to consider the diff/patch couple as ascii text
manipulation utilities that should not depend on the architecture.  May be
the version of patch is the problem?  However, if this is the case, I'd say
it could be better to provide patches that are good for more versions of
the utility; is there a chance for such a solution?


Also, building any particular package with 'make PACKAGE=...', I get the
following:

# build@...pi ~$ make PACKAGE=owl-setup
[...]
# Usage: fgrep [OPTION]... PATTERN [FILE]...
# Try 'fgrep --help' for more information.

# build@...pi ~$ fgrep --version
# fgrep (GNU grep) 2.13
# Copyright (C) 2012 Free Software Foundation, Inc.
[...]

Not yet understood what particular fgrep option triggers this.  The funny
thing is that the build actually continues after these messages, and in
some cases it successfully completes.

Some of these (e.g. lilo (?)) are simply unneeded on Raspberry; as of now,
I'm going to try without them all.

Anyway, during all the builds I see  '-march=armv6' on the gcc's command
line, and 'armv6hl' suffix in Pidora's package names.  What should I add to
ExclusiveArch?  armv6? armv6hl? Both?



Thanks!
