Undefined Reference/Makefile problem

[E.Moyse]

Hi.

Apologies in advance if I'm being stupid here, but I've trawled through
the mailing list archives and I can't find anything that helps me.

I have a fairly simple project which only contains a few files... however
yesterday I started getting this error on compile:

triggerdisplay.o: In function `TriggerDisplay::TriggerDisplay(QWidget *,
char const *)':
triggerdisplay.o(.text+0x3e): undefined reference to
`LVL1::JetElementKey::JetElementKey(void)'

The problem is easy to find - there's no JetElementKey.o file in the
directory. Everything else is compiled okay - it's just this file that
isn't.

I looked at the Makefile and sure enough there's no mention of
JetElementKey. I tried doing DistClean/Rebuild All but the Makefile still
doesn't contain any mention of the file(s). This is really weird because
they're in the same directory as everything else.

I've probably done something stupid but does anyone know what?

Thanks for any help,

Ed
