I built uwebsockets with vcpkg：vcpkg install uwebsockets

You need to enable C++17, this project is using modern C++ features

[zhlongfj]

I got that errors while I compiled it with C++17.(ISO C++17 Standard (/std:c++17))

[ddevienne]

Using the { .field = ... } notation is a C++20 feature, not C++17...

If you could please stick to pure C++17 (which I'm just about to be able to use at work...),
that would be great Alex. My $0.02... --DD

PS: See https://en.cppreference.com/w/cpp/language/aggregate_initialization
PPS: C++20 is not even officially out yet.

Ah, right. But you don't have to use it, you can construct that structure in old style and pass it in.
