Question : Libnet library

Hi,

i install libnet library on my red hat 8.0.  When i try to compile the sample program with the command "cc tcp1.c -o tcp1.o" the compiler return a message "undefined reference to libnet_init()"  Anyone have a solution?

thanx

Answer : Libnet library

in above compilation commands, since you are doing linking also, so its misleading to name the output as tcp.o
as for convention .o is the extension used for object files
so correct will be
cc tcp1.c -o tcp_exec -lnet
.... if u want just object file, then following is enough
cc -c tcp1.c   this will generate tcp1.o object file
which u can later link with the library to give the executable like this
cc -o tcp_exec tcp1.o -lnet

all this assuming  (-lnet ) is the proper linking directive for the libnet.. check documentation of libnet for confirmation.. they must be having some demo programs too .. with makefile
