Hi,
I am trying to (re)build recent ffmpeg master
(63e62cfbe23de8b362d94f783668620a2cd2b571) on OSX 10.5 ppc. I have
installed latest (2014-08-12) gas-preprocessor.pl from
http://git.libav.org/?p=gas-preprocessor.git
When configuring the build it still complains and asks to install/update
gas-preprocessor. I am not sure whether this is a gas-preprocessor
problem, or an ffmpeg build configuration problem. This used to work. I
don't know when it broke because configuring without gas-preprocessor is
non-fatal, so it may have been broken for months and I haven't noticed.
One thing I've noticed is that -arch ppc doesn't work, but -arch powerpc
does:
$ gas-preprocessor.pl -arch ppc -as-type apple-gas -- gcc -v
unknown arch: 'ppc'
$ gas-preprocessor.pl -arch powerpc -as-type apple-gas -- gcc -v
Using built-in specs.
Target: powerpc-apple-darwin9
