我的程序有编译错误:
/usr/include/sys/types.h:46: error: conflicting declaration ‘typedef __loff_t loff_t’

在我的代码中，我根本不包含任何
types.h，因此我怀疑它必须是包含.h和sys/types.h的那些第三方linux/type.h文件。我该如何解决这个问题？
最佳答案
这似乎是一个普遍的问题，但是提到的解决方案却大不相同。
一种合理的解决方案是在libpcan.h或Qt header 之前自己包含两个 header 之一。我不知道是哪一个，因此您必须尝试两者。如果失败，则尝试同时包含两个和两个订单。
