在Eclipse中构建项目时遇到问题

Question

在Eclipse中构建项目时，我得到了以下输出：

make all 

Building file: ../Source/gettimeofday.c

Invoking: GCC C Compiler

gcc -I"/root/Desktop/Eclipse/openwsman/Header" -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -

MF"Source/gettimeofday.d" -MT"Source/gettimeofday.d" -o"Source/gettimeofday.o" "../Source/gettimeofday.c"

../Source/gettimeofday.c:38: warning: ‘struct timezone’ declared inside parameter list

../Source/gettimeofday.c:38: warning: its scope is only this definition or declaration, which is probably not
 what you want

../Source/gettimeofday.c: In function ‘gettimeofday’:

../Source/gettimeofday.c:41: error: dereferencing pointer to incomplete type

../Source/gettimeofday.c:41: error: dereferencing pointer to incomplete type

make: *** [Source/gettimeofday.o] Error 1

有问题的一行是：

int gettimeofday(struct timeval *tv, struct timezone *tzp)

此函数在头文件中声明。

你能帮帮我吗?

GCC吐槽struct timezone未申报在文件中的几行以下，它会报告取消对指向不完整类型的指针的引用。我怀疑gettimeofday.c:41使用了tzp参数。您是否包含了struct timezone的声明？在我的系统上，它是用/usr/include/linux/time.h声明的。
