i am following a book (Foundation of Gtk+) and when i compile these files :

http://pastebin.com/0wNV6Feb

http://pastebin.com/iK0cfMY6

the terminal output this (gcc ipaddresstest.c $(pkg-config --cflags --libs gtk+-2.0)) :

ipaddresstest.c :(. text + 0xC9): undefined reference to "my_ip_address_new"

ipaddresstest.c :(. text + 0xD2): undefined reference to "my_ip_address_get_type"

ipaddresstest.c :(. text + 0xF6): undefined reference to "my_ip_address_set_address"

/tmp/cclTaXSL.o: in "ip_address_changed" function:

ipaddresstest.c :(. text + 0x183): undefined reference to "my_ip_address_get_address"

collect2: error: ld returned 1 exit status

i didn't find nothing about this. Where is the mistake?

PS: can you tell me about guide of this argument for gtk3?

You're referencing symbols which cannot be resolved. Could it be because you have no mention of myipaddress.c, which has the function definitions, when you are invoking gcc?
