Raspberry Zero W: Running ok but Debugger with error

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.

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.

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.

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...

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!

:cry:

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