Wireshark · Wireshark-dev: [Wireshark-dev] HELP: about tshark shared library.

[Pankaj Yadav <p.yadav@xxxxxxxxxxx>]

Hi All,

I want to create a shared library for tshark (using wireshark-0.99.8).
For that, i copied tshark.c as libtshark.c[where i change main() to tshark()] then i add tshark.c [whre i called tshark()] and added tshrk.h

Then I did:
(1) object file for libtshark.c as:
/bin/sh /usr/bin/libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I../.. -I./../.. -I./..    -I/usr/local/include  '-DPLUGIN_DIR="/usr/local/lib/wireshark/plugins/0.99.8"'  -DINET6 -D_U_="__attribute__((unused))" -g -O2 -Wall -W -Wdeclaration-after-statement -Wendif-labels -Wpointer-arith -Wno-pointer-sign -I/usr/local/include -pthread -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include    -MT libcleandissectors_la-libtshark.lo -MD -MP -MF .deps/libcleandissectors_la-libtshark.Tpo -c -o libcleandissectors_la-libtshark.lo `test -f 'libtshark.c' || echo './'`libtshark.c

 gcc -DHAVE_CONFIG_H -I. -I../.. -I./../.. -I./.. -I/usr/local/include -DPLUGIN_DIR=\"/usr/local/lib/wireshark/plugins/0.99.8\" -DINET6 "-D_U_=__attribute__((unused))" -g -O2 -Wall -W -Wdeclaration-after-statement -Wendif-labels -Wpointer-arith -Wno-pointer-sign -I/usr/local/include -pthread -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -MT libcleandissectors_la-libtshark.lo -MD -MP -MF .deps/libcleandissectors_la-libtshark.Tpo -c libtshark.c  -fPIC -DPIC -o libtshark.o

(2) created libtshark.so.0.0 file as:
gcc -shared -g -Wl,-soname,libtshark.so.0 -o libtshark.so.0.0 libtshark.o -lc

(3) ldconfig as:
ldconfig -n .

(4) symbolic link as:
 ln -sf libtshark.so.0 libtshark.so

(5) Object file for tshark.c as:
/bin/sh /usr/bin/libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I../.. -I./../.. -I./..    -I/usr/local/include  '-DPLUGIN_DIR="/usr/local/lib/wireshark/plugins/0.99.8"'  -DINET6 -D_U_="__attribute__((unused))" -g -O2 -Wall -W -Wdeclaration-after-statement -Wendif-labels -Wpointer-arith -Wno-pointer-sign -I/usr/local/include -pthread -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include    -MT libcleandissectors_la-tshark.lo -MD -MP -MF .deps/libcleandissectors_la-tshark.Tpo -c -o libcleandissectors_la-tshark.lo `test -f 'tshark.c' || echo './'`tshark.c

 gcc -DHAVE_CONFIG_H -I. -I../.. -I./../.. -I./.. -I/usr/local/include -DPLUGIN_DIR=\"/usr/local/lib/wireshark/plugins/0.99.8\" -DINET6 "-D_U_=__attribute__((unused))" -g -O2 -Wall -W -Wdeclaration-after-statement -Wendif-labels -Wpointer-arith -Wno-pointer-sign -I/usr/local/include -pthread -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -MT libcleandissectors_la-tshark.lo -MD -MP -MF .deps/libcleandissectors_la-tshark.Tpo -c tshark.c  -fPIC -DPIC -o tshark.o

(6) Final Compilation
