New slackware install with gcc --version 15.2.0 throws
errors like
typer.c:9:3: error: too many arguments to function typer; expected 0, have 1
9 | typer(input);
| ^~~~~ ~~~~~
when compiling a program that used to compile without warnings
(even when using --pedantic) on earlier versions.
Here's a "minimum working example"...
#include <stdio.h>
int main ( int argc, char *argv[] ) {
char *input = (argc<2? "no input" : argv[1]);
#if defined(WORKS)
int typer(char *);
#else
int typer();
#endif
typer(input);
return(0); }
int typer ( char *input ) {
printf("Your input was: %s\n",input);
return(0); }
Note that typer() takes one char * arg,
but is declared as int typer() in main()
with no args when compiled as gcc typer.c -o typer
And that worked fine on earlier gcc versions.
But now it throws those errors.
However, when compiled as gcc -DWORKS typer.c -o typer
which declares int typer(char *) with its arg,
then it works, of course.
I've got lots of code that declares functions
without their args, and that compiled fine for
years and years, but now throws those errors.
Is there some gcc -switch (or --switch or whatever)
that will ignore that "error" without rewriting
anything? Thanks,
