Failed to build with Boost 1.77.0

[yurybura]

I'm working for update Boost for VCPKG (PR microsoft/vcpkg#19556).
I've detected a problem to build qwtw library on x64-windows:
failure logs for x64-windows.zip
Could you help?

Sorry I didn't looked here for some time.. Will try to look into this

Any progress?

Or, sorry, looks like I moved qwtw to C++20. For me it looks like the C version is not what is expected..

our CI passed this item(VS2022) but I can repro the same issue locally (VS2017).

[ig-or]

yes, it looks like VS2022 is using C++20, and VS2017 is previous version.. Will try to repro this locally, maybe there will be some solution
