Re: Bug#153948: Need help with afio on powerpc

[Koen Holtman <koen@hep.caltech.edu>]

Hi all,

Thanks for all the testing of my recent patched version.  Good to hear
that it works..

Dirk: with respect to your question 
>Does that mean that I should undo the powerpc conditional which removes
>those two flags, but can leave them for everything else?

I made (on purpose) no explicit recommendation about this in my
earlier mail, but only outlined my understanding of the level of
unstability you would get, because I don't quite know how much
unstability you want in a Debian unstable branch.

BUT based on the tests by Stephen and Dieter I now recommend that in
the 2.4.7-7 unstable version, the -D_FILE_OFFSET_BITS=64
-D_LARGEFILE_SOURCE flags are enabled on all platforms including
powerpc, because without them writing a >2GB archive should not work
(according to my limited understanding so far of the large file
support documentation).

The next thing on my todo list is to close-read the large file
documentation which I dug up, and then see if more changes to afio are
needed.  The goal is to create a source code base for which I know
definately that afio will behave correctly under the various possible
compile options.  Though this becomes more of a non-linux and
ancient-linux support issue than a powerpc support issue.

Cheers,

Koen.
