Code::Blocks Forums

Hi there !

I'm using Code::Blocks since few years and I like it ! But there is an option that I cannot use, and I don't know what is wrong in my use... #defines.

Look : I create a target named "debug", with DEBUG 1 in the #defines tab. Then, I write :
int main()
{
#ifdef DEBUG
cout << "debug" << endl;
#endif
/* ... */

return 0;
}

It should show "debug" in the console, but it doesn't... What's wrong ?

Thank you !

PS : I'm using GNU GCC compiler...

A lot of reads, but no answer.... Is it so complicated ? :P

It looks like it should work to me.

I would try using a define other than DEBUG; the standard is NDEBUG to say not debug.
and then to test for #ifndef NDEBUG

I am a C::B newbie, so there could be something C::B related that I don't understand.

I tried this :
#ifndef ZAFDSGERGEG
cout << "debug" << endl;
#endif
with ZAFDSGERGEG defined....
And it showed "debug" : it shouldn't :x

I really don't understand :?

Where are you defining it?

The standard location in CB is
Project -> Build Option
Compiler Tab; #defines Tab

In the defines tab you have to put DEBUG=1. Notice no spaces and the equality sign.
Edit: Anyway, I tried and it should also work with only having "DEBUG" in the defiens tab.
Did you...
- put the define in a wrong target (e..g in the release target but compiled the debug target?!)
- forget to re-compile after you had changed the define?
- do you set DEBUG=0 somewhere in the code that gets included?
With regards, Morten.

Code Select Expand

Works very well for me. Did you forget to re-compile?

Okay, here's my real code :
/* debug.h */
#ifdef ZAFDSGERGEG
#include <iostream>
using namespace std;
#define echo(text) cout << text
#else
#define echo(text)
#endif
This code is helpful to show somemore informations when I'm debugging my sources...

And for your questions :

QuoteDid you...
- put the define in a wrong target (e..g in the release target but compiled the debug target?!) NO
- forget to re-compile after you had changed the define? NO (maybe yes actually, but I just recompile completely and the problem is still present...)
- set DEBUG=0 somewhere in the code that gets included? NO

It is not the first time I tried to use the defines, but it never worked...

Ok, I reinstalled C::B, and now it works...
Thank you for the help !
