Version 1.4 broken on Windows

[sroller]

Environment: Windows 10, msys2, ruby 2.5.3p105 x64

When I install the gem version 1.4 the installation fails with a link error: can't find dlopen().
I reverted to version 1.3.11 of the gem and things where fine.
Let me know what additional information you need.

Try adding the mingw-w64-x86_64-dlfcn package, then running gem install. I assume that you have mingw-w64-x86_64-sqlite3 installed...

I think:

ridk exec pacman -S mingw-w64-x86_64-dlfcn

Yes, that worked. We should change the comment in the README.md of the rubyinstaller2 project to reflect on this change.

Glad that helped. I think that 'dlfcn' should be added to:

sqlite3-ruby/sqlite3.gemspec

Line 10 in 5c36dbe

s.metadata = { "msys2_mingw_dependencies" => "sqlite3" } if s.respond_to? :metadata=

and/or the following should be modified when building on Windows:

sqlite3-ruby/ext/sqlite3/extconf.rb

Lines 67 to 71 in 5c36dbe

	have_library 'dl'
	%w{ dlopen dlclose dlsym }.each do |func|
	abort "missing function #{func}" unless have_func(func)
	end

haven't had a chance to look into it...
