Embedded system and shared libs

Embedded system and shared libs

[Miguel Ángel Álvarez Cabanes]

Hi

Sorry for sending this question twice in a week, but I think I didn't
explain correctly the first time.

- I use a PPC in an embedded system.
- If I build iptables with NO_SHARED_LIBS=1 there is no problem (kernel
2.6.10 has netfilter options enabled).
- If I try to build iptables without NO_SHARED_LIBS and copy the
libipt*.so to /lib/iptables on my system, I can test the tables
(iptables -t nat -L), but I cannot do MASQUERADE or so... I obtain:

"iptables v1.3.0: Couldn't load target `MASQUERADE':File not found

Try `iptables -h' or 'iptables --help' for more information."

Thanks for all

Miguel Ángel

The default location for the iptables shared objects is
/usr/local/lib/iptables, did you change this? have you tried to use
strace to find out where iptables looks for the shared object files?

I have tried placing the shared objects
in /usr/local/lib/iptables, /usr/local/lib, /lib, /lib/iptables... with
the same result.

Is there anything appart from the executable and the shared objects that
must be placed in the system to relate them?

About strace... I have not tried with it, because I do not have strace
on my embedded system, but I think it can be a good idea and I am going
to try to add it.

Thanks

Miguel Ángel
