Will C compile .so to work with a C ++ application?

Question

If I want to dynamically link a shared library (.so) for a C ++ application (which was created using g ++) using LD_PRELOAD, it matters if .so is generated from the C source file (using gcc) or the C + Source file + (using g ++)? Why or why not?

Thanks for helping me figure this out.

Answer 1

Yes, a C ++ executable can be linked (both statically and dynamically) to the C library.

This is completely deliberate. C ++ ABI are designed for backward compatibility.
