Thanks JoeByte! 

Glad to hear it worked for you as well ... if only Apple would not have screwed around removing GDB ... 

I can't open the actual debugger. How do I do it? If I try to click on the Lazarus icon in Safari, I should get some options, but all I really get is a loading screen. 

I'm not sure what you mean ... I'd love to help though.

To download GDB, click or right click the link in the first post of this topic (link). Once downloaded, follow the instructions in that post to unpack and install.
Once installed, Lazarus will call the GDB automatically when you run an application from Lazarus. Typically you will not see anything from GDB unless you're stepping through code or when something goes wrong.

I'm not sure what you mean with the "the Lazarus icon in Safari" ...?

For convenience, I decided to create a package that does the all job alone.

Is attached.

Thanks Messias Henrique!

Slick! 

Hello all

Ive done everything on the tutorial above and it worked fine.

I tried to execute a little simple program to see if it would work in my computer.

Follow the programming code:

program example;

uses crt;

var

name : string;

begin

name:= hello ;

writeln(name);

readln;

end.

When I press play it returns with an error

There where 1 error compiling module, stopping.

Does anyone know why this happens?

Hi Acvoliveira,

well, this could be for several reasons.

First of all, the compiling error of this code has not related to do with the debugger - there is something wrong with your code.

Second point is that this seems a command-line application - did you do the proper settings in the compiler settings for this?

It could be my code, but I've everything the installation tutorial in many site wrote to do.

Is there a webpage explaining who to configure the compiler for this? I don't know if there is any misconfiguration because Larazus is finding all the write files to execute. But there could be some configuration that a I didn't do.

Can you help me with it, please?

Try this Lazarus Wiki page on how to create a console application. 

Thanks. This helped!

Thanks Dakab1 for leaving a positive feedback - glad it worked for you as well! 

Unfortunately, this trick no longer seems to work under El Capitan (Mac OS X 10.11).
I'm still trying to figure out the correct procedure to get a working GDB ...

Alright! Found a trick that actually works! 

Note: 

I just tried this with macOS Sierra Beta 2 ... and the trick works here as well ... 

I just tried this on Seirra 10.12.2 and can't get it to work, the debugger says it's timed out.

Does the gdb file need code signing?
