verbosity of compiler

[Leseratte <bookreader at gmx dot com>]

Hello,

I'm stuck in template developing and I would like to know, whether the 
verbosity of compiler output could be increased?
Especially the decisions made, that lead to certain error?

I'm quite sure, that I made some mistakes, but I don't know, how to get rid of 
them.

One error message for example is this:
		error: expected primary-expression before ')' token
     TimerType::startTimer<mode, ps> ( );

and another looks like 
	error: no match for 'operator<' (operand types are '<unresolved 
overloaded function type>' and 'hal::timer::TimerMode')
     TimerType::startTimer<mode, ps> ( );


Its the same source line which results in different error messages. 
I would like to know: 
- why is the function unresolved?

How can I find out, which of my definitions where accepted by the compiler and 
which are rejected?
Is there somewhat like a debugging mode or verbose mode - that outputs the 
different compiler steps?


best regards

Reinhard
