I am using UE5.3.2. When creating a C++ Project, it shows a Compiler Error:

I am using Visual Studio 2022 17.12.4 and MSVC 14.42.34436, and I selected Windows 11 SDK 10.0.22621.0. I don’t know what I installed incorrectly, and I only have Visual Studio 2022 on my machine.

BUMP! I followed the “Setting Up Visual Studio” from Epic Games website and I’m having the same issue. I hope this question get answered soon.

Hi there,

I encountered a similar issue with the combination of UE5.3.2 and Visual Studio 2022 (version 17.12.4), and here’s how I resolved it:

  1. Updating WindowsPlatformCompilerSetup.h:
    The error related to the compiler version detection can be fixed by updating the version check.
  • Navigate to Engine\Source\Runtime\Core\Public\Windows\WindowsPlatformCompilerSetup.h.
  • Open the file in a text editor (ensure the file is not marked as read-only).
  • Locate this line:
#if defined(_MSC_VER) && _MSC_VER > 1939
  • Change 1939 to 1948:
#if defined(_MSC_VER) && _MSC_VER > 1948
  • Save the file and put it on read-only again. This should eliminate the warning about the compiler being newer than Visual Studio 2022.
  1. Fixing the __has_feature error:
    The second issue arises from a __has_feature directive in the header ConcurrentLinearAllocator.h, which causes a compiler error.
    To resolve it:
  • Navigate to Engine\Source\Runtime\Core\Public\Experimental\ConcurrentLinearAllocator.h.
  • Find the line:
#elif __has_feature(address_sanitizer)
  • Replace it with:
#elif 0
  • This will bypass the __has_feature check and allow the build to proceed without cascading errors.

Hope this helps!

The WindowsPlatformCompilerSetup.h has bugged me for ages, how do you know that it is 1948, like where/how is that number defined?

Second of all, apparently you can also uninstall C++ Address Sanitizer via the VS Installer, but I don’t know if that is a safer way to deal with the ConcurrentLinearAllocator.h.

I couldn’t find the specific number through Google, so I tested a few values, and 1948 worked for me.
Regarding the C++ AddressSanitizer, I’m not entirely sure about its implications. I chose to let the Unreal Build Tool to bypass the issue in ConcurrentLinearAllocator.h. However, uninstalling the C++ AddressSanitizer might resolve the problem.

UGH THANK YOU
