Hi!
I'm trying to make xmpp module, to do this I'm configurating according
to my file system several files (xmpp_component.c, util.c, xmpp.c ...).
But I get error while compiling the file 'network.c'.
I don't know where these errors come from because the rest of the files
are OK.
These are the errors and my 'network.c' file:
Any help would be wellcomed.
Izortze.
