Ruby-win64 support with libcurl-x64.dll

[wutai3]

Hi, I use typhoeus for ruby-win64 enviroment.

Because curl-x64 official dll is "libcurl-x64.dll", so DLL load have failed. https://curl.se/windows/

D:\>ruby -v
ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x64-mingw-ucrt]

Could it change setting file below?

ethon/curls/settings.rb 

-   ffi_lib ['libcurl', 'libcurl.so.4']
+    ffi_lib ['libcurl', 'libcurl.so.4', 'libcurl-x64']

Thanks.

Does your suggested change work for you?

For me, it looks like adding an entry for libcurl-4 worked for me.

However, I'm using msys2's ucrt version of curl via ridk on Windows 10.

Oh, its site advised to download official 'libcurl.dll' file..
https://rastating.github.io/fixing-issues-in-typhoeus-and-httparty-on-windows/
https://stackoverflow.com/questions/22525093/typhoeus-windows-installation

I used its way and it works.

Hi, but "libcurl-x64.dll" way also works. Which is pefer better?

• ffi_lib ['libcurl', 'libcurl.so.4', 'libcurl-x64']
