I'm new to C/C++.
When I import , the license text looks as follows:

This is the GPLv3 license. This applies to all libraries, e. g. , too. The files lie in
/usr/include/c++/9. Do I understand it correctly, that if I use any of the standard libs, my program needs to be GPL, too? How is this done in practice, when I dont want it to be GPL? Thanks
I have also googled and have done some research, but its still unclear to me.
