c - 为交叉编译器构建 newlib 时“gettimeofday”的类型冲突

Question

在尝试构建 newlib 1.20.0 时...我遵循了本教程http://wiki.osdev.org/OS_Specific_Toolchain#newlib.2Flibc.2Fsys.2Fmyos

但是在尝试构建 newlib 时出现以下错误：

/../newlib-1.20.0/newlib/libc/sys/myos/'`syscalls.c
../../../../../../newlib-1.20.0/newlib/libc/sys/myos/syscalls.c:29:5: error: conflicting types for 'gettimeofday'
In file included from ../../../../../../newlib-1.20.0/newlib/libc/sys/myos/syscalls.c:7:0:
/usr/src/newlib-1.20.0/newlib/libc/include/sys/time.h:74:5: note: previous declaration of 'gettimeofday' was here
Makefile:280: recipe for target `lib_a-syscalls.o' failed

sycalls.c 用于 gettimeofday 声明：

int gettimeofday(struct timeval *p, struct timezone *z);

时间.h：

int _EXFUN(gettimeofday, (struct timeval *__p, void *__tz));

那么什么是冲突类型？请帮助....任何帮助表示赞赏...

更改syscalls.c 中的函数声明。然后将 void * 转换为结构时区。
