Recent versions of GCC and Clang have gotten strict about function prototypes since C23 made the following: int foo (); equal to: int foo (void); In previous versions of C this was not true, 'foo' was just declared as a function without any information about number of arguments or their type. C23 also got rid of K&R declarations like: int main (argc, argv) int argc; char *argv; { ... } This is why you now see the warnings after upgrading to Fedora 42 with a new C compiler. Try building from the 'devel' branch where prototypes have been fixed. Collin
