will clean it later.

[qicosmos]

could you build with latest code?

[kassane]

could you build with latest code?

using: zig c++ == clang++ -stdlib=libc++ -fuse-ld=lld

Cmd:

• clang++ -stdlib=libc++ example/main.cpp -Iinclude -o http_server_test -Ithirdparty/async_simple/ -std=c++20 -Wextra
• zig c++ example/main.cpp -Iinclude -o http_server_test -Ithirdparty/async_simple/ -std=c++20 -Wextra

Using the same setting in both tools results the same output.

Output
