VC6: fatal error C1083: Cannot open include file: 'stdint.h'

Question

When compiling in VC6 I am receiving the error:

(fatal error C1083: Cannot open include file: 'stdint.h': No such file or directory)

Can anyone explain why I am receiving this error?

does int #include line say "stdint.h"? or <stdint.h> – Argus

See #12970793 and #6689395 – Goodkin

Apparently Microsoft only supports C89, although I think VC6 was released in 1998, so it couldn't be expected to support C99 anyway. But even in their latest compilers, Microsoft doesn't support C99. – Goodkin

I had a similar issue:

Stop.

I found this answer which mention that using VS 2017 Command prompt can help. I used 2008 so I searched for 2017.

For those who has Visual Studio 2017 and can't find the Command prompt like me, open CMD and run: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\Tools\VsDevCmd.bat"

Notice that I had the folder named Enterprise, but you might have a different folder (maybe Community or something else).

After that, I ran it and it worked good:

C:\Users\<myuser>>"C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\Tools\VsDevCmd.bat"

C:\Users\<myuser>>cd C:\Users\<myuser>\Desktop\Putty For Windows\windows

C:\Users\<myuser>\Desktop\Putty For Windows\windows>nmake -f Makefile.vc

I also created a shortcut with this command:

C:\Windows\SysWOW64\cmd.exe /k "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\Tools\VsDevCmd.bat"  

Placed it here:

C:\Users\<myuser>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs

Doesn't answer why the header wasn't available in antique VC6. The answer is simply that the compiler is far too old. – Edette
