Rahul,

you need to also link the object file where the function
SCTP_receive (and many other functions) are defined.
That file is sctp_wrapper.o
You probably also need to include the file sctp_wrapper.h
in your source file (which should be in terminal.c already).

The statements:
gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I./../sctp -g -O2
- -I/usr/include/glib-1.2 -I/usr/lib/glib/include -D_REENTRANT -D_THREAD_SAFE
- -Wall -DLINUX -c sctp_wrapper.c
gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I./../sctp -g -O2
- -I/usr/include/glib-1.2 -I/usr/lib/glib/include -D_REENTRANT -D_THREAD_SAFE
- -Wall -DLINUX -c terminal.c

should compile sctp_wrapper.c and terminal.c and create sctp_wrapper.o
and terminal.o.

The command:
gcc -g -O2 -I/usr/include/glib-1.2 -I/usr/lib/glib/include -D_REENTRANT
- -D_THREAD_SAFE -Wall -DLINUX -o exp_terminal terminal.o
sctp_wrapper.o ../sctp/libsctp.la -rdynamic -lgmodule -lglib -ldl

should then link the object files and create the new terminal program
you want.

Hope that helps,

Andreas
