Does this instance even work, it looks broken, like it is missing
something?
Tested both static and shared building. All working with no
noticeable
speed difference although I didn't formally bench.
It's generally a good idea to check for and report the speed
differences. Even if just for the sake of curiosity.
So, with this configure:
--disable-doc --disable-w32threads --enable-pthreads --disable-
autodetect --cc="ccache gcc" --enable-static --enable-shared --extra-
ldflags="-static" --enable-gpl --enable-version3
I ran one priming run + 5 repeat runs of `time make -j4`.
Before, real ranged from 2m10.188s to 2m12.154s
After, real ranged from 2m12.486s to 2m13.405s
I also ran one priming run + 5 repeat runs of `time make -j4
libavcodec/libavcodec.a libavcodec/avcodec.dll`.
Before, real ranged from 1m34.232s to 1m42.721s
After, real ranged from 1m32.360s to 1m39.484s
I presume this command compiled the whole of FFmpeg/libavcodec, i.e. it
did not just link, didn't it?
Its deps, are *.o in lavu, lswr, lavc, but after the priming run, all
the cc steps would be cache hits,
so the bulk of the fresh executions are the linking steps.
Plan to push tomorrow.
Did you not try to use GNU make's flie function?
I just benched this and it ranges from 1m28.093s to 1m29.971s (5%
faster) for the lavc targets.
However, this was added in make 4.0. Are we supporting older make?
Regards,
Gyan
