the problem is caused by "/usr/include/bits/fcntl2.h":
for gcc,
__errordecl (__open64_too_many_args,
"open64 can be called either with 2 or 3 arguments, not more");
is:
extern void __open64_too_many_args (void) __attribute__((__error__ ("open64 can be called either with 2 or 3 arguments, not more")))
while for clang, __fortify_use_clang is defined:
static __attribute__((__unused__)) __attribute__((__overloadable__)) int open64 (const char *__path, int __oflag, mode_t __mode, ...) __attribute__ ((unavailable("open64 can be called either with 2 or 3 arguments, not more")));
so in case clang, there are two symbols named open64, cause:
> error: address of overloaded function 'open64' is ambiguous
> error: initializer element is not a compile-time constant
