Hi.
Just wanted to let you know I am getting close to packaging R for
AIX in
64.bit mode.
Which version? (You mentioned 3.1.3 and 3.2.2 far below.) There is
little value in reporting on frozen branches, and most value in
reporting on R-devel where all the current changes have been
incorporated.
This report is based on R-3.2.2 I shall repeat asap with R-devel and
report any significant differences.
In particular - I wonder about lzma as I already knew this (having
built xz a long time ago. LZMA has been replaced by XZ. Do not know
why, and do not want to.
BUT there is no reliable source for LZMA5 (the XZ project only reports
LZMA2 and LZMA4). Please see the wiki at:
https://en.wikipedia.org/wiki/XZ_Utils
Paused for now - awaiting reply
Well, seems I stand corrected - it is not a change since 17 October, but
since R-3.2.2 and some directories have been removed from R distribution.
However, I am wondering about this logic - of requiring both lzma and
xz, whereas before xz was required if lzma was not available.

If I read the XZ portal - they say XZ is based on LZMA (and it seems the
lzma support you are looking for comes from xz. So, what the false fail
on lzma - as it seems it is only XZ you are looking for, or need.)
Having this more clear I can now understand the logic of your numbering
(taking the version # of LZMA from XZ with the compression algorithm
being LZMA2)
Anything re: gotchas between 3.2.2 and R-devel is appreciated.
