Thread: Help configuring Geany

Hi have been using GDB online Debugger | Compiler - Code, Compile, Run, Debug online C, C++but now decided to use Geany. However whenever I try and compile my code I get a whole lot of "incompatible implicit declaration" warnings.

Why does it work in one environment and not the other? I have looked through the preference and can not see any obvious way to address this.

Without seeing your code how can we answer your question?

Geany is just an editor.

What compiler do you use on your system?

What O/S is your system?

What C Standard does GDB online us?

What C Standard does your compiler use?

It sounds like your code is missing include files. Try adding these lines to the beginning:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

You may need others (and may not need all of those).

I think, OnlineGDB.com compiler might be having those warnings, Because it just run program, if there is no compiler errors, warnings are just ignored. So you may not be able to see actual warnings thrown by gcc compiler.
Whereas with geany you run it locally and can see those warnings thrown by geany.
btw, I was just wondering why did you choose to use geany over onlinegdb compiler.

Once again, Geany is an IDE, or fancy editor! It is NOT a compiler! Like all IDE's, Geany CALLS a preinstalled compiler! You can even change the compiler or edit the compiler command in the "Build menu commands dialog" within the Geany settings, along with other settings, such as make, lint, and others as appropriate for the language being edited.
