在为交叉编译器构建newlib时，“gettimeofday”的冲突类型

Question

当试图构建newlib 1.20.0时..。我遵循了本教程Toolchain#newlib.2Flibc.2Fsys.2Fmyos

但是，当试图构建newlib时，我会得到以下错误：

/../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

用于gettimeofday声明的sycalls.c：

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

时间h：

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

那么，什么是冲突的类型？？请help....any帮助，谢谢.

Answer 1

更改syscalls.c中函数的声明。然后将空*抛到结构时区。
