Error 'Failed to pull libOmxMpeg4Dec.so. Giving up.' when building B2G for Unagi phone

[Henrik Skupin]

Hi all,

Yesterday I got my Unagi phone and flashed it with the build from Nov
7th (grabbed from https://releases.mozilla.com/b2g/). Then I have
noticed that it is based on Aurora and wanted to flip to
mozilla-central. So I have setup a local build system. After running the
configure step for the unagi phone I started build.sh. But after a
couple of minutes the build process stopped with the following failure
when creating the backup:

[..]
> > pull: /system/sources.xml -> ../../../backup-unagi/system/sources.xml
> > pull: /system/build.prop -> ../../../backup-unagi/system/build.prop
[..]
> > Pulling "libOmxH264Dec.so"
> > 4796 KB/s (189376 bytes in 0.038s)
> > Pulling "libOmxMpeg4Dec.so"
> > remote object '/system/lib/libOmxMpeg4Dec.so' does not exist
> > Failed to pull libOmxMpeg4Dec.so. Giving up.

Is that a hard-coded list of files to backup, or is it a failure in the
build system? Just pushing a faked file with that filename fixed it for now.

Thanks

Hi Henrik,

I had the same problem when I received my unagi a few days ago. I don't
know if this is an issue with the phone or the sources, but you can
workaround it by removing the respective line from the file

device/qcom/unagi/extract-files.sh

A patch is attached.

I've seen that this file was added by the last commit. cc'ing
efl...@mozilla.com.

Best regards
Thomas

Is that a hard-coded list? If yes it's clear why we are failing then. We
should probably ignore any warning here to make it less pain to switch
between different versions of Firefox OS (Nightly vs. Aurora).
