Templates will be the end of me

Why does this not compile? I have some very similar code elsewhere, and it compiles. I just cannot figure it out.
Ataru,
You didn''t define your constructor. If its still giving you problems, you should post the source for the GEOMETRY class also.

Found the problem. I did define the constructor, in the cpp. That was the problem, when I moved all the definitions into the .h everything compiled.
I have learned once again, do not try to use a cpp file with templates.

Indeed, never do. I inevitably forget this when working with templates and inevitably screw up every time too. Maybe MS should fix their damn compiler.

Thank god I''m not the only one. This has bitten me several times before. Maybe it''s my "no fear" mentality. Like I believe I can actually compile it that way, so I force myself to forget.
Hopefully it''s the last time.

So should GCC.
And Digital Mars.
And Intel.
And Borland.
And Metrowerks.
Ad nauseum, minus Comeau with a command line switch.

Hmm, maybe... if you''d been following the discussion some years ago on implementing export you might''ve known that separate compilation for templates is not a two day fix, more like three man-years or something (according to EDG the only ones who has done it). Read this and this to get a better view of the actual problem and why it might not even be so desirable to have after all. Then go to google-groups comp.lang.c++.* and search for "export" to read some more...
No, templates will not be the end of you, we won't let that happen you son of a bitch! Oh... problem already solved. Carry on.
.inl files or inline implementation aren't that bad anyway.
