Subject: problem with template and global/static variable

I just come from comp.lang.c++ where they told me I should ask here as it
must be a gcc linker problem. I hope you can help me.

I created a template that I can only use as a member of an object. If I try
to use a static or global variable of the template type I get a linking
error (gcc 2.7):

Clients.cpp:26: undefined reference to `Collector<int>::Collector(void)'

I have no idea why. It looks like that a constructor Collector(void) is
needed? The Collector template has a public constructor Collector(). Can't
this be used for global/static variables? Do I have to code another public
constructor for Collector: a Collector(void)?
