ODBC Driver dbg

Hi everyone

I sincerely hope this mailing list is not inactive,

I want to write a ODBC Driver that simply does selects.
So I downloaded the Postgres ODBC driver source and started looking at it.
It is really neatly written I should add!

I however wonder how one would go about debugging it?
I would like to be able to query something from say... DBeaver ot my
local postgres DB and then STEP through the functions as it goes until
the select process is done. To just see what exactly is happening...
Is there some way I can do that? Which tools will allow me ...
Preferably not Visual Studio since I am on LINUX.

How would the developers of this driver go through something like that?

Thanks
