Hi,
Below there's the strace dump: I don't know very much about it, but
it seems it is not reporting any important issue, maybe that is
different to your eyes.
The _LGPL_SOURCE and printf strategy:
- intilially, Busybox built complained about liburcu-bp
dependency missing
- when added, it builds but something goes wrong when OpenWRT
boots because it is not completing init scripts
I will try the dynamic linking strategy for the provider...
Thanks,
Santi
