Package builds fine for lucid but fails for karmic

Please check your build log more carefully.

Building on one series doesn't guarantee it works on other series, because most of your runtime and build dependency packages will have changed.

In your case:
gcc -o gtk-sunlight sunlight.o callbacks.o `pkg-config --libs gtk+-2.0 gmodule-2.0`
sunlight.o: In function `main':
sunlight.c:(.text+0x1a4): undefined reference to `g_thread_init'

Well, this is exactly what I mean. My dependencies which are (libgtk2.0-0, pkg-config, libgtk2.0-dev) haven't changed from lucid to karmic.

If I'm using the same dependencies why is it failing? Can you be a bit more clear, please.

I also just before the bit you mention I get this message, not sure if this is important:
gpgv: Signature made Wed Jun 16 20:36:50 2010 UTC using RSA key ID A33E7E92
gpgv: Can't check signature: public key not found

and thank you for your patience

I'm sorry, this Answers section is about Launchpad Soyuz, not packaging
issues, I can't help beyond what I've already mentioned. You could try asking
in #ubuntu-moto on Freenode.

That is fine, it's just a warning.
