I was trying to write the program from the scratch. Here is the program. [code] #include <stdio.h> #include <avahi-client/client.h> #include <avahi-client/lookup.h> #include <avahi-common/cdecl.h> #include <avahi-common/watch.h> #include <avahi-common/malloc.h> #include <avahi-common/error.h> #include <avahi-common/simple-watch.h> static AvahiSimplePoll *simple_poll = NULL; int main(int argc , char* argv) { AvahiClient *client = NULL; AvahiServiceBrowser *sb = NULL; int error; int ret = 1; /*Allocate main loop object */ if (!(simple_poll = avahi_simple_poll_new())) { //TODO } //TODO } [/code] And error is Here lsf@lsf-laptop:~/mesh_project/dalesa/src/im$ gcc publish_service.c /tmp/ccavp1Yk.o: In function `main': publish_service.c:(.text+0x27): undefined reference to `avahi_simple_poll_new' collect2: ld returned 1 exit status What is the wrong with this?

I don't remember what is the command, but I think that is pkg-config --cflags --libs avahi-client pkg-config --cflags --libs avahi-server I'm not sure, but yes, you need the CFlags. -- Atte.
