重新聲明sys / types.h和linux / types.h

Question

我的程序有編譯錯誤：

/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’

在我的代碼中，我根本不包含任何types.h ，因此我懷疑它必須是包含sys/types.h和linux/type.h第三方.h文件。

我該如何解決這個問題？

Answer 1

這似乎是一個普遍的問題，但是提到的解決方案卻大不相同。

一種合理的解決方案是在libpcan.h或Qt頭之前，自己包括兩個頭之一。 我不知道是哪一個，因此您必須嘗試兩者。 如果失敗，請嘗試同時包含兩個和兩個訂單。
