Any tutorial about Dev C++ debugging feature?

[asmileguo]

I just found its help document is somewhat perplexing...

Dev-C++ is probably facing the end of its days. There is no development being done on it other than an early project at http://wxdsgn.sourceforge.net/. Dev-C++ as is, is most probably dead.

Regardless the debugger GUI in Dev-C++ is pretty straightforward (albeit rather useless). What is that you are having trouble with?

[asmileguo]

When I click "debug", it keeps on saying "your project doesn't have debugging information. Do you want to add the debugging information and rebuild the project?" I went through it by "Yes" several times, and it's still like this, without any other debugging information showing up...

[asmileguo]

And the only responese I got from the debug output window is:
you need to put the debug mode on before you debug.

What does it mean? Where is the on/off thing?

[Mario F.]

Ah. Gotcha.

You have to compile your program with debug symbols. In other words, you have to compile it for debugging. Go to menu Tools->Compiler Options. In the Compiler tab make sure "Add the following commands when calling compiler" is checked. And add "-g3" (without the quotes) to text box bellow it.

Compile and link your program normally after doing this. Then you will be able to debug.

Thanks Mario; I'll give it a try.

Mario, is it "-g3" or "-gdb"? Something is not quite right; I can't quit the GDB in the window even I type "quit" and press "send" in the debug command window.

[asmileguo]

Could I just use the command window for debug instead of the GUI?

[Mario F.]

You could and you should, in my opinion. All the power of gdb is better shown in the console.

The GDB documentation is better than most tutorials:
http://www.delorie.com/gnu/docs/gdb/gdb_toc.html

However, if you still prefer a tutorial look around google for "gdb tutorial"

Seek a confirmation: can it be installed and run in Windows?

[Mario F.]

GDB comes as part of MinGW. When you installed Dev-C++ you installed an editor. It just happens it is bundled with the MinGW compiler and GDB.

So it is already installed under the bin folder of Dev-C++.

Thanks! I found it!!
