Microsoft C ++编译器，严重错误C1083：无法打开包含文件“ stdio.h”

Question

I have the following C file.

#include <stdio.h>

I open an instance of Developer Command Prompt for VS 2017 and type the command.

cl [my-file.c]

I get the following error message

fatal error C1083: Cannot open include file: 'stdio.h': No such file or directory.

I am unsure how to resolve this problem.

Answer 1

The include directories for the current session are stored in the INCLUDE environment variable.

You can view this by typing echo %INCLUDE% on the command prompt.

To add a directory to the include path, use the command set INCLUDE=%INCLUDE%;C:\\foo\\bar .

The fact, however, that the compiler isn't finding a standard and ubiquitous header like <stdio.h> indicates a serious problem with your Visual Studio installation. I would run a repair install if I were you.

Answer 2

The include path needs to be set up, did you launch cmd with one of the developer command prompts?
