Permission Denied Error when Running 'make' in '/Document/test' directory

[EkenoSamson]

I'm encountering an issue when trying to run 'make' in the /Document/test directory while following the YouTube video(C-Language: C Ninja, in Pyjama! - #0. Lab Setup!) at 12:44

c-ninja@c-ninja-linux ~/Documents/test
% make
riscv64-unknown-elf-gcc -O0 -ggdb -nostdlib -march=rv32i -mabi=ilp32 -Wl,-Tmain.ld main.s -o main.elf
/usr/lib/riscv64-unknown-elf/bin/ld: cannot open output file main.elf: Permission denied
collect2: error: ld returned 1 exit status

I have also attached the screen of my terminal.

Here are the details when I run uname -a in my terminal.

I am using ubuntu.

When I use sudo make and provide the required password, it successfully generates the desired output. It appears that this resolves the issue.

Thank you, @EkenoSamson for opening the issue!

It looks to me that the c-ninja user doesn't have the write access to the path ~/Documents/test. Could you help run the following command and share the output?

ls -al

Unfortunately, I did not try the setup on a Linux machine. I will try to reproduce the error on that. In the meantime, can I also request you, to try adding the c-ninja user to the sudo group using the commands below?

sudo usermod -aG sudo c-ninja

I am hoping the make command will work as expected after this.

This is happening because while mounting test folder to container's ~/Documents/ directory, user files are being mounted as owned by root while preserving file permissions.
This issue and issue comment will help - moby/moby#3124 (comment)

The permissions for test folder indicate write permissions for others are not enabled hence not allowing other users to create output file main.elf

Please run to give other users write access in the folder

sudo chmod +007 ../test/

Post that, again run make and we should be able to see the o/p

the following is the output after I ran ls -la command.

I tried entering my Ubuntu Login Password, but its not taking. Is there any different password?

@7022106205: The password for the c-ninja user is c. Your login password won't work within the docker image 😊

Let us know if this helped.

It worked, thank you.

@EkenoSamson:

Can you try the following and see if this resolves the permission issue? I tried this locally on an Ubuntu machine and seemed to work well -

c-ninja@c-ninja-linux ~/Documents
% sudo chown -R c-ninja .

I am able to execute the make command without sudo as below:

@streetdogg
I tried it and it's working. Thank you.
