Cannot change to working directory «...»: file or directory not found

alexanderzhirov

Installed Lubuntu 20.04.02, installed Qt Creator 4.14.0 based on Qt 5.15.2. All settings are fine, compilers/assemblers/debuggers are configured. I am creating a project with terminal support. In system settings, x-terminal-emulator is installed with the -e parameter. Lubuntu itself has the qterminal terminal, the only one. I'm trying to put together a trivial project with the ability to enter data - the build is successful:

#include <iostream>

using namespace std;

int main()
{
    int a = 0;
    cout << "Enter value: " << endl;
    cin >> a;
    cout << "a = " << a << endl;
    return 0;
}

I am trying to run a project - I get an error in the application output:

Cannot change to working directory «/home/user/Programming/build-test-Desktop_Qt_5_15_2_GCC_64bit-Debug»: file or directory not found

As I understand it, the problem is not new and I want to solve it without resorting to installing additional terminal emulators ... I ask for help from the knowledgeable.

P.S. In other IDE's, everything is compiled and run in an embedded terminal.

Confirm how you have set to run qterminal -e? You are saying you have done this, aren't you?

If you don't get a better answer (and I don't think you will!) I would:

Verify you can run qterminal as a command, and verify you can run qterminal -e ls or similar.
Temporarily replace qterminal -e from being the terminal command with something which prints exactly whatever it receives on the command line to a log file so we can see just what the full command line Creator is generating reads. I don't know why a problem at the executable level would cause "your directory not found", but let's see if it gets as far as your log.

Yes, I set qterminal directly.

I don't quite understand what you mean. But I can launch Qt Creator through the terminal and get the output of messages to the terminal when I run my program:

Yeah, the console output you have just pasted is doubtless the issue. It may have nothing to do with qterminal vs xterm, or anything else. I don't know why though. Ensure you can create that path, though I'm sure you can.

Which then takes you all the way back to xterm after all via https://stackoverflow.com/questions/14010521/cannot-connect-creator-comm-socket-tmp-qt-temp-jh2103-stub-socket-no-such-file

I think you're on your own figuring why qterminal is problematic....

P.S.
https://bugreports.qt.io/browse/QTCREATORBUG-6007 from 2011.

Everybody ends up using /usr/bin/xterm -e :)

Yes, i know it:)

But need to understand why this does not work with QTerminal. On github, they believe that it has nothing to do with it.

The question is still open.
