Fixes: https://autobuild.buildroot.net/results/924b1015d4b81385409ef00f1a14be3ca1959c8e/ As part of building flex for the target a few files are built for the host, including a rpl_malloc() implementation containing a malloc() forward declaration without any function parameters. GCC 15 defaults to -std=gnu23, which handles function declarations without parameters differently from earlier C standards leading to compilation errors: ../lib/malloc.c:6:12: warning: conflicting types for built-in function 'malloc'; expected 'void *(long unsigned int)' [-Wbuiltin-declaration-mismatch] 6 | void *malloc (); | ^~~~~~ ../lib/malloc.c:5:1: note: 'malloc' is declared in header '<stdlib.h>' 4 | #include <sys/types.h> +++ |+#include <stdlib.h> 5 | ../lib/malloc.c: In function 'rpl_malloc': ../lib/malloc.c:16:15: error: too many arguments to function 'malloc'; expected 0, have 1 https://gcc.gnu.org/gcc-15/porting_to.html#c23-fn-decls-without-parameters Add a patch submitted upstream to correct the prototype.
