Sure I perfectly understand your point of view, I also agree that it's
better to proceed step by step with everything, or we'll only get
frustrated by the this overcomplicated world.

I just mean that for a software developer programming is not enough, you
must also know your compiler well enough, and your build system.
Otherwise you will:
1. miss many opportunities to write/test much better your code
2. feel like you're using a black box, and be stuck on some product to
   build code that maybe would be perfectly portable everywhere.

Sorry clicking doesn't work for me either, what you should do is the
following

evaluate this or set it in your .emacs:
(setq gdb-many-windows t)

g++ -ggdb hello.cpp
M-x gdb RET
And it will prompt you how to run gdb, for example:
gdb --annotate=3 a.out

the annotate is very important otherwise emacs will not be able to
follow the execution.

then you should have on top the gud/gdb buffer, where you can type very
normal gdb commands.
Otherwise you open any source file and with "C-x space" you should be
able to set your breakpoints.

To know more just look in the GUD menu on top or the info page.
