I have a code that uses std=c 20.

I want to use a C library that was build with old gcc version.

Should I recompile the C library using the same compiler ?

If no, how could you judge that the 2 ABIs are compatible?

CodePudding user response：

There should be no problem using the library as it is. Don't forget to add extern "C" around the function prototypes.
