I tried to compile a socket programming code under SUN Solaris by using g++, i get the following errors:

Undefined first referenced
symbol in file
__xnet_connect /var/tmp//ccidZvCu.o
__xnet_socket /var/tmp//ccidZvCu.o
getaddrinfo /var/tmp//ccidZvCu.o
freeaddrinfo /var/tmp//ccidZvCu.o
gai_strerror /var/tmp//ccidZvCu.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status

Note: the program compiles under Linux - Ubuntu.

Any help? Where can i find the library? How can i link it to my code?

The best way to figure out if a function is available with Solaris is to look for a man page.

Eg:

man getaddrinfo

cc [flag ...] file ... -lsocket -lnsl [library ...]

Yes its there, i included the libraries, its still does not work:


cc [flag ...] file ... -lsocket -lnsl [library ...]
#include <sys/socket.h>
#include <netdb.h>

You do not include libraries, you include plain text include files.

Libraries are linked to using the -l flags.

Did you use them ?

no i didn't....I have never used them, i'm a newbie can you please guide me more?

I did this g++ fileName -lsocket -lnsl

Worked!

Thanks
