sys/types.h和linux/types.h的重新声明冲突
sys/types.h和linux/types.h的重新声明冲突
提问于 2012-02-07 19:50:22
我的程序有编译错误：
/usr/include/sys/types.h:46: error: conflicting declaration ‘typedef __loff_t loff_t’
/usr/include/linux/types.h:30: error: ‘loff_t’ has a previous declaration as ‘typedef __kernel_loff_t loff_t’
/usr/include/sys/types.h:62: error: conflicting declaration ‘typedef __dev_t dev_t’
/usr/include/linux/types.h:13: error: ‘dev_t’ has a previous declaration as ‘typedef __kernel_dev_t dev_t’
/usr/include/time.h:105: error: conflicting declaration ‘typedef void* timer_t’
/usr/include/linux/types.h:22: error: ‘timer_t’ has a previous declaration as ‘typedef __kernel_timer_t timer_t’
/usr/include/sys/types.h:198: error: conflicting declaration ‘typedef long int int64_t’
/usr/include/linux/types.h:98: error: ‘int64_t’ has a previous declaration as ‘typedef __s64 int64_t’
/usr/include/sys/types.h:204: error: conflicting declaration ‘typedef long unsigned int u_int64_t’
/usr/include/linux/types.h:97: error: ‘u_int64_t’ has a previous declaration as ‘typedef __u64 u_int64_t’
/usr/include/sys/select.h:78: error: conflicting declaration ‘typedef struct fd_set fd_set’
/usr/include/linux/types.h:12: error: ‘fd_set’ has a previous declaration as ‘typedef struct __kernel_fd_set fd_set’
/usr/include/sys/types.h:235: error: conflicting declaration ‘typedef __blkcnt_t blkcnt_t’
/usr/include/linux/types.h:124: error: ‘blkcnt_t’ has a previous declaration as ‘typedef long unsigned int blkcnt_t’在我的代码中，我根本没有包含任何types.h，所以我怀疑一定是那些包含sys/types.h和linux/type.h的第三方.h文件。
我该如何解决这个问题？

这似乎是一个常见的问题，但提到的解决方案却大相径庭。
一个合理的解决方案是在libpcan.h或Qt标头之前包含两个标头中的一个。我想不出是哪一个，所以你得两个都试一试。如果此操作失败，请尝试在两个订单中都包含和。
