stdlib issue when build in linux

[DxTa]

Hi,

I tried to build the example in linux (Ubuntu 22.04 - amd64). Currently, I get the following issue.
I did updated few lines of code here. This solved the issue.

Anyway, I want to double check if this is expected?

Br,

@DxTa I guess it is caused by different C++ compilers.The reference to 'stdlib.h' may be necessary for some 'strict' compilers.
The function 'system' is weird that some compilers need a variable to handle the return value, i will check if there is anything wrong.
