sorry wrong forum, but if anyone know how to do with it, it would be great.
Thanks in advance,

Hmmm... it seems I won't be able to compile it with the docker. I'm using Ubuntu 16.04 32bit and just read this on the docker documentation:

Docker requires a 64-bit installation regardless of your Ubuntu version.

Saldly, my old laptop doesn't support it.

my linux package name is linux-108e489c19d92800dfc7f04ec93f57468ffff751.tar.gz is it right ? i take this on https://github.com/digitalLumberjack/recalbox-buildroot/commit/a74a9e3d93edacc7f465a03ac07bc8e7e47b8d2b
