Hi,
i tried it again but without success
so what i have tried to do is just change the main of tcpreplay.c to be a
function that i will call it in my project.
my_function(int c,char* v[])
{
/*copy of the main of tcpreplay.c*/
}
i have compiled it and i got all the needed .o files, i have used the same
makefile (it is huge and really i couldn't understand all as libtool and
autogen... to figure out how should i compile it) :: i got error for build of
binary (no main) of tcpreplay which i don't need it but i got at the end the
objects files
and i have created the tcpreplay library using this shell script
#!/bin/sh
AR="ar"
ARFLAGS="cru"
libtcprewrite_a_AR="$AR $ARFLAGS"
libtcpreplay_a_AR="$AR $ARFLAGS"
LIBOPTS_LDADD="../libopts/libopts.la"
libtcprewrite_a_LIBADD=
libtcpreplay_a_LIBADD="./common/libcommon.a ../../lib/libstrl.a
/usr/lib/libpcap.a ../libopts/libopts.la"
LIBTOOL="libtool"
RANLIB="ranlib"
am_libtcprewrite_a_OBJECTS="tcpreplay-tcpreplay.o \
tcprewrite-tcprewrite_opts.o"
am_libtcpreplay_a_OBJECTS="tcpreplay-tcpreplay_opts.o \
tcpreplay-send_packets.o \
tcpreplay-signal_handler.o \
tcpreplay-tcpreplay.o \
tcpreplay-sleep.o"
libtcprewrite_a_OBJECTS="$am_libtcprewrite_a_OBJECTS"
libtcpreplay_a_OBJECTS="$am_libtcpreplay_a_OBJECTS"
rm -f libtcprewrite.a
rm -f libtcpreplay.a
$libtcpreplay_a_AR libtcpreplay.a $libtcpreplay_a_OBJECTS $libtcpreplay_a_LIBADD
$RANLIB libtcpreplay.a
#$libtcprewrite_a_AR libtcprewrite.a $libtcprewrite_a_OBJECTS
$libtcprewrite_a_LIBADD
#$RANLIB libtcprewrite.a
and i have compiled my project using this libraries too -lcommon -lstrl -lopts
-ltcpreplay -lpcap
but it doesn't work
here are the linker errors: the problem is that all these undefined references
should exist in the libraries --> so i have built wrong libraries.
