Raspberry Zero W: Running ok but Debugger with error

[codemonster]

Hello
my servoprogram is well running but when I want to debug with breakpoints I get this error message:

"No executable file specified.
Use the "file" or "exec-file" command."

my settings:
working Directory: /home/pi/myprod/cpptest/p12-servo/Debug
Compiler otions: -ggdb;-std=c++11
Debugger Settings in Project Settings: empty fields
Global Debugger Settings: Debugger Path = empty

After pressing OK in the error box the code-window is blinking 4 times

Code: Select all

#include <stdio.h>
#include <wiringPi.h>
#include <iostream>
#include <unistd.h>


int main()
{
	int i {1};
	int k {10};

	std::cout << "i verdoppelt :" << ++i << std::endl;
	std::cout << "k verdoppelt :" << k * 2 << std::endl;

	if (wiringPiSetup () == -1) //using wPi pin numbering
		exit (1) ;

	pinMode(1, PWM_OUTPUT);
	pwmSetMode(PWM_MODE_MS);
	pwmSetClock(384); 
	pwmSetRange(1000);
	pwmWrite(1, 75);  
	usleep(1000 * 1000);
	//goto ww;
	pwmWrite(1, 60);
	usleep(1000 * 1000);
	pwmWrite(1, 80);
	usleep(1000 * 1000);
	pwmWrite(1, 50); 
	//ww:
	return 0 ;
}

Can somebody help? Do you need some more informations regarding my settings?
Thank you

The error is that the sudo in"executable to Run/Debug = sudo ./$(ProjectName)" not operates in Debug mode (only in release mode) in Codelite or I don't find out how I can setup this.
The codeline "pwmSetMode(PWM_MODE_MS)" needs a sudo started gdb.
It's also possible that this is an error in Codelite 10.0.0. But this is the newest version that is running on my Raspy Zero W.

[DavidGH]

Hi,

No promises that I'm right, but I think you need to tick the 'Use separate debug args' box, and put the sudo into 'Debug Program Arguments'. You might also need temporarily the 'sudo' from 'Executable to Run/Debug'.

If that isn't the answer, the next thing to do is to try running in a terminal. See what happens with:
~> gdb --args sudo /full/path/to/your/ExecutableName

Regards,

David

Hi,
what a shame, your first tip doesn't works.

The program works fine with gdb in terminalmode. This also was my way to find out that codelite 10.0.0 doesn't starts gdb with sudo.

[DavidGH]

The program works fine with gdb in terminal mode

Out of interest, what was your successful command? The one I suggested, or just: gdb sudo /path/to/program ?

your first tip doesn't works.

OK. Please turn on Full Debugger Logging. (You can do that from the Settings > GDB: Misc menu, or by ticking the 'Enable Log' box in the Output tab of the Debugger Pane.) Try to debug your program and you'll get a lot of output from gdb.

You may see something there that explains the problem. Otherwise please paste the output here.

[codemonster]

Thank you very much for helping me!!!

with this command the program was running with gdb on terminal: sudo gdb ./Debug/program

So all is well until:
Datei oder Verzeichnis nicht gefunden

I don't know what it can't find, sudo or ./p12-servo-test. You could try (in your 'Debug Program Arguments' field) replacing sudo with /usr/bin/sudo (if that's the correct path in your pi); and ./p12-servo-test with /full/path/to/p12-servo-test in your 'Executable to Run/Debug' field.

However:

with this command the program was running with gdb on terminal: sudo gdb ./Debug/program

You were running gdb itself under sudo; that's different from what you're telling CodeLite to do, which is:
gdb sudo ./Debug/program

What happens if you do, in the terminal:
gdb sudo ./Debug/program

By the way, do you need to enter a password when you use sudo? If so, I don't know if CodeLite can cope...

[codemonster]

Datei oder Verzeichnis nicht gefunden

it says: file or directory not found

You could try (in your 'Debug Program Arguments' field) replacing sudo with /usr/bin/sudo

Then title of Debugger window: Debugging "sudo ./p12-servo-test" /usr/bin/sudo
...and error

and ./p12-servo-test with /full/path/to/p12-servo-test in your 'Executable to Run/Debug' field.

error

What happens if you do, in the terminal:
gdb sudo ./Debug/program

GDB brings error…. btw yes, sudo is in /usr/bin/

By the way, do you need to enter a password when you use sudo?

no!

[codemonster]

I think it can't find sudo because other programs with no need of gdb-sudo-start are running in gdb.
