c++ - Can Qt compiled libs work with newer compilers?

Question

edit

Now i am really confused , it works , qt libs compiled with gcc 3.4 works with gcc 8.3.1

I cannot understand why

• End of edit*

I am using same linux qt compiled runtime libs ,that was originally compiled with an older g++ 3.x.x compiler and it works for now on different linux systems , tested until g++4.8.5 .

Is it by chance? Am i just lucky?

Will it still work with new g++ std 20 compiler .

Or that i should compile from src for each platform...

Qt is 4.7 , can i use the same libs with c++20 compiler ,without build qt from src.
