vcruntime.h missing from Windows include folder?

I'm a beginner and I'm trying to build an open source project for the first time in Windows, but I keep running into file not found errors when building. What I've found so far is that a header file called corecrt.h is located at C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\. This file would include another header file named vcruntime.h. The problem is that vcruntime.h is nowhere to be found in that folder.

I later found that vcruntime.h is located in a separate folder located at C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.25.28610\include. This is strange because I'm not sure why corecrt.h would include a file that is not in its own filepath...

I did the bone-headed thing of just copying over vcruntime.h file to the C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\, but this just shifts the problem down the road because vcruntime.h in turn also includes other header files located at C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.25.28610\include, and so on.

I think the issue lies with Windows itself. I think I'm missing something that's suppose to install additional header files like vcruntime.h to C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\

So far I've tried uninstalling/reinstalling Windows SDK, and just reinstall Windows as a whole, but still no dice to make the missing files appear in that folder. Can someone give me some insight on this? I've asked this question on Reddit but so far nothing has been able to help.

Here's the link to the instructions I'm following on how to build https://wiki.documentfoundation.org/Development/BuildingOnWindows

I'm building using their suggested environment Lode on my Windows 10 machine.

I get C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\ucrt\corecrt.h(10): error: vcruntime.h: No such file or directory

The error occurs right at the build step and I run make 2>&1 | tee build.log

Solution

  • I too had the same issue, but found the cause which was the Include directories were not specified correctly. To fix this I did the following with Visual Studio:

    1. Right click on the project name, and then click on Properties.
    2. Under Configuration Properties, select VC++ Directories.
    3. The Include directories should contain $(VC_IncludePath);$(WindowsSDK_IncludePath); - correct this.
    4. Click OK to save and Bob's your uncle.
