The same happens in all projects, for example in Pong-Game.

/OS-master/Pong-Game# ./run.sh

try running the linker script with the params --allow-multiple-definition . I think he is declaring variables in the header files.

[arteze]

Thanks, it works for me.

I had seen that they use the parameter in the GCC with -Wl,--allow-multiple-definition, I never imagined that it would go in the linker (ld), it is good to know.

[xing1357]

Yeah, I hope he can update the header file.

[arteze]

Yes, I was able to compile it, as you can see in the image, it is running, and the issue can be closed but when I try to close it with Close with comment, it remains open.

[xing1357]

I think @pritamzope should do that now.
