Hallo Francisco,

you have build your packages using OpenWrt based on the eglibc library.
But default OpenWrt images (available from the website) are based on
uclibc instead. That means your binaries are linked against the wrong c
library and you need to switch to a OpenWrt system which is also based
on eglibc or switch to a toolchain based on uclibc. I recommend the
latter case.

Kind regards,
Johannes
