(fmt->format.h) The following warning is treated as an error

[bipul-mohanto]

Hi! Similar to the previous issue, I guess the fmt library is a problem with Visual Studio 2022. I tried to use the latest fmt library 11.0.2, lowered the warning level, and even disabled the error for warning, but no help. Here is my system:

• Windows 10 (x64)
• Visual Studio Community 2022, version 17.10.5
• build mogwai as release is working fine, but debug build is returning errors:

p.s. the version: Falcor 6.0.

in the format.h -> template <typename T> using checked_ptr = stdext::checked_array_iterator<T*>;

Any suggestion?

[SirKero]

The easiest (but hacky) solution I use is just to disable the problematic part of fmt which is using the checked_array_iterator.
For this I changed #if defined(_SECURE_SCL) && _SECURE_SCL [Line 557, format.h] to #if 0 so it uses the release checked_ptr.

@SirKero, excellent! It is working fine for now. 👍🏽
