The cause code is here. (https://github.com/treasure-data/serverengine/blob/4d6dbd3d1b4e1af88cc2593b5b19cf0f6da7d5dd/lib/serverengine/winsock.rb#L112)

  module RbWinSock
    extend Fiddle::Importer

    dlload "kernel32"
    extern "int GetModuleFileNameA(int, char *, int)"
    extern "int CloseHandle(int)"

    ruby_bin_path_buf = Fiddle::Pointer.malloc(1000)
    GetModuleFileNameA(0, ruby_bin_path_buf, ruby_bin_path_buf.size)

    ruby_bin_path = ruby_bin_path_buf.to_s.gsub(/\\/, '/')
    ruby_dll_paths = File.dirname(ruby_bin_path) + '/*msvcr*ruby*.dll'
    ruby_dll_path = Dir.glob(ruby_dll_paths).first
    dlload ruby_dll_path

    extern "int rb_w32_map_errno(int)"

On 3.0.x, this test is passed.

Moreover, I don't find any changes about rb_w32_map_errno from 3.0.3 to 3.1.0.

It is strange behavior. It may be a bug in Ruby-3.1.0

Environment

• Github Actions (windows-latest)
• use https://github.com/oneclick/rubyinstaller2/releases/download/RubyInstaller-3.1.0-1/rubyinstaller-3.1.0-1-x64.7z
• permalink to failed test (https://github.com/fluent-plugins-nursery/fluent-plugin-bigquery/runs/4775813193?check_suite_focus=true)

I apologize for the lack of research, as I do not have a Windows environment.

• Subject changed from rb_w32_map_errno does not found on Ruby-3.1.0 to rb_w32_map_errno is not found on Ruby-3.1.0

[kubo (Takehiro Kubo)]

It is because of a change in rubyinstaller-3.1.0-x64.

In https://rubyinstaller.org/2021/12/31/rubyinstaller-3.1.0-1-released.html:

RubyInstaller-3.1.0-x64 has a changed C-runtime called UCRT replacing the old MSVCRT.

I guess that ruby_dll_path is nil because *msvcr*ruby*.dll doesn't exist in the bin directory.

rubyinstaller-3.1.0-x64: x64-ucrt-ruby310.dll
rubyinstaller-3.0.0-x64: x64-msvcrt-ruby300.dll
rubyinstaller-3.1.0-x86: msvcrt-ruby310.dll
rubyinstaller-3.0.0-x86: msvcrt-ruby300.dll

How about the following code?

  module RbWinSock
    extend Fiddle::Importer

    dlload "kernel32"
    extern "int CloseHandle(int)"

    require 'rbconfig'
    dlload RbConfig::CONFIG['LIBRUBY_SO']
    extern "int rb_w32_map_errno(int)"

The error itself was fixed by https://github.com/treasure-data/serverengine/pull/116#issuecomment-1011931598.
There is another error in serverengine using ruby 3.1 but it is unrelated to this issue.

I've released a fixed version of serverengine: https://rubygems.org/gems/serverengine/versions/2.2.5
Thanks for your report!
