[Help-gnutls] Re: gnutls with pgp

[dellanna]

Ok,
now, if I run  cc -ex-serv-anon ex-serv-anon.c -I/usr/lib/ -L /usr/lib/ -lgnutls
(for server with anonymous authentication) it work correctly...the output is the
following:

Server ready. Listening to port '5556'

But if I run cc -ex-client1 ex-client1.c -I/usr/lib/ -L /usr/lib/ -lgnutls on
client machine (for client anonymous) it return the following error:
_______________________________________________________________
/usr/bin/ld: warning: cannot find entry symbol x-client1; defaulting to
0000000008048908
/tmp/ccbQ8aPE.o: In function `main':ex-client1.c:(.text+0x97): undefined
reference to `tcp_connect'
:ex-client1.c:(.text+0x1fd): undefined reference to `tcp_close'
collect2: ld returned 1 exit status

What is the problem for you?
