I'm being 'driven' toward building a powerpc64 environment 'from scratch'
by a few different forces:
- Ubuntu stopped building powerpc releases at 12.04; my current
has some has configuration issues, while overall it works well
packages held back due to fontconfig1 -- I think; aptitude wants to back-rev
about 35 different things so that I can get libs to build ffmpeg sorted out>
- I believe the firewire interfaces -- from a hardware point of view -- were
"as good as it gets" on the G5 workstations
- vendor support for firewire-ppc devices on OSX is more or less
in the music business
- multi-CPU powerpc machines can be "had for a song" since Adobe dropped
support for CS4
- IBM spent a ton of dough on software to make their servers work; and they
do a pretty good job on documentation.
So, "from an engineer's point of view" a PPC64x4CPU "water cooled
is "great bang for the buck" to support my keynote application; digitizing
Hence, "dragged into compiled kernels". I started linux on a G3 wallstreet
running yellow dog, so its not really "new turf". While I may not make hay
getting there, i'm penning this note to let you know that efforts on your
part will bear fruit; and I'll do my best to archive decent explanations of
what I've done to figure out the details along the way.
With that written, I've come across another clue. The book "Cross-Compiled
Linux From Scratch
Version 2.1.0-PowerPC64-Pure64" details that the "-m64" parameter SHOULD be
within this environment variable:
excerpted from page 31
5.3. Build Flags
We will need to setup target specific flags for the compiler and linkers.
I can't really think of a reason that libffado should/would handle it
as this seems a setup detail specific to the compiler. I'm really not
how scons handles environment details, as this is my first time working with
Perhaps you can suggest a debugging string that I can add to the SConstruct
files to output how this parameter is handled? I've done a basic grep on all
these files and
found no existence of a "BUILD64" parameter, and having a bit of trouble
figuring out how
env.MergeFlags handles the mapping between environment variables and string
assignments in SConstruct.
