It's just a single .c file in the project. Here's the code:

bool
不是 C 类型。我确实怀疑
BOOL
是在某个地方定义的。true
和false
的使用也是如此。bool
is not a C type.I do suspect
BOOL
is defined somewhere.Same goes for the usage of
true
andfalse
.实际上,假设您使用的是最新的编译器,
bool
是 C99 标准中的有效类型(实际上是宏)。您需要添加:请注意,
bool
在旧版 ANSI、C89、C90 等 C 标准变体中无效。正如 JeremyP 在评论中强调的那样,微软的 C 编译器仍然缺乏对 C99 功能的适当支持。
这就留下了三种选择:
bool
作为内置类型bool
实现bool
对于选项 2 类似这可行,但这是一个丑陋的解决方法:
Actually,
bool
is a valid type (well, a macro actually) in the C99 standard, assuming you are using a recent compiler. You need to add:Note that
bool
is not valid in the older ANSI, C89, C90 etc variants of the C standards.As highlighted by JeremyP in the comments, Microsoft's C compiler still lacks proper support for C99 features.
Which leaves three alternatives:
bool
as a built-in typebool
implementationbool
For option 2 something like this would work, but it's an ugly work-around:
