[Buildroot] [PATCH 0/1] package/ffmpeg: Fix ranlib check when cross-compiling

[Bernd Kuhls]

Hi,

this is a different approach to fix the build error.
Please compare my patch with http://patchwork.ozlabs.org/patch/461843/

I am not sure what the best fix would be, therefore I have not yet
sent my patch upstream.

Regards, Bernd

I've applied this patch. Please submit it upstream, and give us some
feedback on upstream's reaction. One thing I'm wondering is whether
with your patch, the --ranlib= option continues to work.

Best regards,

Thomas

 I'm OK with either solution. I propose that you send your patch upstream, see
how they react, and if it's positive then we go with yours. If they don't accept
it, then I think that not patching (i.e. my solution) is better.

 Regards,
 Arnout
