“ uint32_t”标识符未找到错误

我正在为 Windows 将代码从 Linux C 移植到 Visual C + + 。

Visual C + + 不知道 #include <stdint.h>，所以我把它注释掉了。

后来，我发现了很多 'uint32_t': identifier not found的错误，怎么解决呢？

This type is defined in the C header <stdint.h> which is part of the C++11 standard but not standard in C++03. According to the Wikipedia page on the header, it hasn't shipped with Visual Studio until VS2010.

In the meantime, you could probably fake up your own version of the header by adding typedefs that map Microsoft's custom integer types to the types expected by C. For example:

typedef __int32 int32_t;
typedef unsigned __int32 uint32_t;
/* ... etc. ... */

Hope this helps!

Boost.Config offers these typedefs for toolsets that do not provide them natively. The documentation for this specific functionality is here: Standard Integer Types

There is an implementation available at the msinttypes project page - "This project fills the absence of stdint.h and inttypes.h in Microsoft Visual Studio".

I don't have experience with this implementation, but I've seen it recommended by others on SO.

On Windows I usually use windows types. To use it you have to include <Windows.h>.

In this case uint32_t is UINT32 or just UINT.

All types definitions are here: http://msdn.microsoft.com/en-us/library/windows/desktop/aa383751%28v=vs.85%29.aspx

You can #include <cstdint>. It's part of C++-standard since 2011.

I have the same error and it fixed it including in the file the following

#include <stdint.h>

at the beginning of your file.

I had to run project in VS2010 and I could not introduce any modifications in the code. My solution was to install vS2013 and in VS2010 point VC++ Directories->IncludeDirectories to Program Files(x86)\Microsoft Visual Studio 12.0\VC\include. Then my project compiled without any issues.
