c - OSX 10.5.8 下出现 undefined symbol 错误

Question

我尝试在 OSX 10.5.8 下使用 CFLocaleCopyCurrent 但出现奇怪的错误:

#include <CoreFoundation/CoreFoundation.h>

int main(int argc, char **argv){
    setlocale(LC_ALL, "");
    CFLocaleRef loc = CFLocaleCopyCurrent();
    return 0;
}

Undefined symbols:
"_CFLocaleCopyCurrent", referenced from: _main in ccn51XwH.o

尝试 /usr/bin/gcc -framework Foundation test.c
