Debug a C# or Python program outside the environment

Dfdd · 24 August 2021 01:38

When I try to debug a C# or Python program in Visual Studio Code in an external terminal (with bash) it gives me the following error:

/usr/bin/bash: cannot execute binary file

after seeing that error I try to call bash from the Manjaro console with the executable file:

bash executable

and it gave me the same error that visual studio code showed. I was only able to run the file without getting an error with the following command:

bash -c executable

Now the questions I have are the following:

Why VSCode neither in Ubuntu nor in Manjaro Gnome (which I had installed last week) did not give me this error and in Manjaro KDE it did?
How can I fix this problem?

Any help or advice is very welcome

Note: With VSCode’s internal terminal I have no errors (which is very rare) and although I can work normally with the internal terminal, I still prefer the external one with which I am adapted.

Are the permissions set properly?
You can check with ls -l /path/to/dir of the file.
It should say something like -rwx-r-x-r-x at the begining of the line.
If it doesn’t have x anywhere then run sudo chmod +x /path/to/executable

Why VSCode neither in Ubuntu nor in Manjaro Gnome (which I had installed last week) did not give me this error and in Manjaro KDE it did?

Probably messed up the permissions copying the file between three different systems.

megavolt · 24 August 2021 03:30

Hello @Dfdd

So my idea about this, is:

bash executable assume that this file is a bash script and therefore through this error.
bash -c executable is the same as bash ./executable or ./executable. There it assumes it is a binary, if not, then it interprets the script (sure Shebang must be set: #!/usr/bin/env bash)

No idea why it works on Ubuntu and Manjaro Gnome, but that behaves normal for me.

Dfdd · 24 August 2021 03:47

Yes, I check out that and permissions are fine

Dfdd · 24 August 2021 03:51

Oh my mistake … the command that works is:

bash -c ./executable

I have to correct the post.

What doesn’t work is:

bash -c executable

and

bash ./executable

megavolt · 24 August 2021 03:54

well then just run:

./executable

Why would you need bash, since you are already on the bash shell?

What file is it?

file executable

Dfdd · 24 August 2021 04:00

Yes, this works. But the problem here is that apparently what visual studio code does behind the scenes to execute the code in an external console is to call the command

bash executable

or

bash ./executable

and what I want is the external terminal to appear automatically as Visual Studio Code always has done and not having to invoke it myself

Dfdd · 24 August 2021 04:06

What really breaks my mind here is that in Ubuntu and even in the Gnome version of Manjaro I simply wrote the command and it did not give me an error and now with Manjaro KDE it happens to me that I have to write it that way and I don’t know why . The worst of all is that it even hinders the operation of the visual studio code for external terminals

megavolt · 24 August 2021 04:42

Which Terminal and Shell?

echo -e "Terminal: $TERM\nShell: $SHELL"

I have this:

Terminal: xterm-256color
Shell: /bin/zsh

I tested it myself

bash script.sh
bash -c script.sh (if chmod +x)

cp /usr/bin/ls ~/bin && cd ~/bin

bash ls
bash -c ls

Well yes confirmed…

Maybe a workaround would be an alias:

alias bash="bash -c"

at ~/.bashrc.

source ~/.bashrc

Then you can run:

bash executable

linux-aarhus · 24 August 2021 04:59

Not being able to execute either a script or a binary from the folder containing the file (and not in the path) is by design and cannot be changed.

As a security measure *nix-like systems only allows execution by name if the executable is in the path.

If you want to execute something within the current folder it must be prepended with the path to the executable.

This can be the full path or using a dot which designates current folder.

Dfdd · 24 August 2021 05:02

Yes, this works but it is a temporary solution since doing this I can no longer execute the .sh files

Dfdd · 24 August 2021 05:07

I read about it a few hours ago … but we are losing the central point of this thread which is to know why the invocation of the external terminal by VSCode drops that error in Manjaro KDE but it did not drop it in Manjaro Gnome or in Ubuntu… and above all, how do I solve this?

linux-aarhus · 24 August 2021 05:18

It appears to be an issue with VSCode - not the system in question.

I can think of one theory - but I don’t know if it hold - it contains the following elements

Microsoft has always executed scripts and exe from current folder
Powershell follow *nix tradition - also on Windows - where you must include the path eg. .\program.exe
When Microsoft implemented WSL it was by using Ubuntu
Ubuntu is using Gnome as the default DE
VSCode is a relatively new code editor developed by Microsoft

I see Ubuntu, Gnome, VSCode as the common denominators - where KDE falls outside - which is why the correct message is thrown.

Good question - How about creating an issue with the VSCode developers?

Dfdd · 24 August 2021 05:22

ok, thank you very much for your attention and dedicating a little of your time. Looks like I’ll have to put this as a flaw in VSCode

Dfdd · 24 August 2021 05:25

Thanks for the help anyway

Dfdd · 28 August 2021 18:31

Well, I managed to solve this problem. The key is that I set the external console to call “bash” and bash is not an external console as such. In Manjaro KDE the external console by default is “konsole” and then that was the one I sent to execute.
That is, in the visual studio code settings go to “Features > Terminal” and in the option called “External: Linux Exec” you change whatever you have written for the name of the external console. In the case of Manjaro KDE the external console is called “konsole” and that solves the problem
