[sclug] C++ Linking to libpg++ problem

Hi

Thanks for the tips :-) After much fiddling about I resolved the problem by 
adding:

Project -> Options -> Compiler Options -> Configure Tab -> Additional Options 
- -> --with-extra-includes=/usr/include/pgsql

Most of the problem was just figuring out how kdevelop expected me to add the 
- --with-extra-includes option.

One last thing I am wondering - how would I go about adding more than one 
include path in the above example?

Cheers

Tim
