Compiling Hello World plugin

[Sindhu Sundar]

Hi!

I intend to write a plugin for pidgin, which will show all online
buddies in a tooltip when the cursor hovers over the system tray.

I read the wiki page on how to write a plugin in C, the hello world
plugin but I have been receiving these errors when I compile.

sindhu@sindhu-eee:~/Desktop/Code/Online_Buddies_Tooltip/pidgin-2.5.5/libpurple/plugins$
gcc -o helloworld helloworld.c
helloworld.c:34:18: error: glib.h: No such file or directory
helloworld.c:46:20: error: notify.h: No such file or directory
helloworld.c:47:20: error: plugin.h: No such file or directory

helloworld.c:146: error: expected ‘{’ at end of input
sindhu@sindhu-eee:~/Desktop/Code/Online_Buddies_Tooltip/pidgin-2.5.5/libpurple/plugins$

I don't know how to proceed from here. I have basic knowledge about C,
I have compiled code in C on my Ubuntu system before this, but never
my own code.

Please help. Thanks :)

You will note that this is *not* how the HOWTO tells you to compile
the plugin.  There is a reason for that.  If you follow the
instructions in the HOWTO carefully, it should compile.  (I.e., using
'make' to compile your plugin, in this case.)

try this in the same directory:
$ make helloworld.so
