debug flags

debug flags

[John C. Arrakis]

Hello,

I would like to have some code for debugging reasons in a big project
that I'm working on, but not via commenting and uncommenting source
code lines, as this will be too time-consuming. So, I wonder if there
is some way to make gcc create some kind of a global variable or a
definition or something like that, that will allow me to inject in my
source files pieces of code like this:

# if SOME_DEBUG_FLAG
    do_some_debugging_stuff ();
# endif

I searched in the man pages, but I wasn't able to find anything
related to this subject. Any help will be much appreciated!

Cheers,
John.

I think the option -D should do what you want. 

Using -D at the commandline you can define any preprocessorsymbol which can
be tested during compilating using #ifdef or #if statements.
