installation of earlybird fails on Windows 7 x64 bit

[PavelKotov1]

Hello, dear friends! Please help me in my quest: learn how to debug ocaml code in Visual Code Since the prerequisite for OcamlDebugger is earlybird, i tried to install it first. opam install earlybird fails with those results: Error report <><><><><><><><><><><><><><><><><><><><><><><><><><><> +- The following actions failed | - build cmdliner 1.0.4 | - build dune 2.4.0 | - build ocamlbuild 0.14.0 | - build ocamlfind 1.8.1

I can be wrong, but it looks like the root of all evils is : ** Fatal error: Cannot find file "ws2_32.lib" Visual Code info: Version: 1.43.0 (system setup) Commit: 78a4c91400152c0f27ba4d363eb56d2835f9903a Date: 2020-03-09T19:47:57.235Z Electron: 7.1.11 Chrome: 78.0.3904.130 Node.js: 12.8.1 V8: 7.8.279.23-electron.0 OS: Windows_NT x64 6.1.7601

Sorry, I can't help you for that. Can you install other library as expect?

[hackwaly]

@PavelKotov1 Have you solved your problem?

[PavelKotov1]

not yet... but I am trying to.

[PavelKotov1]

OK, somehow everything worked just fine on Windows 10 x64. So whatever it takes, the matter is closed! Thanks for the great tool!

[PavelKotov1]

Ok, I have to reopen the case, due to some unexpected behavior of the debugger. Looks like earlybird is installed, [NOTE] Package earlybird is already installed (current version is 0.1.4). but VS code cannot see it and reacts with "no debug adapter" message when I press F5. Debugging icons appear on the tool bar and disappear in about 5 seconds. If I try to use ocamldebug on my a.out file produced by ocamlc -g, outside of the Visual Code IDE, it works fine, but the idea is to be able to step through the code in graphic UI. I use VS code 1.43 on Windows 10 x64, and have Cygwin bash running in my terminal. I also have Ocaml Debugger and Ocaml and Reason IDE extensions installed. Can their potential conflict cause the problem? Your help will be greatly appreciated!

[PavelKotov1]

I think I have found the answer, could be useful to others, who is strugliing like me: if you’ve already got a working OCaml environment on Windows, including OPAM and Merlin (probably a Cygwin environment), you just need to make sure you open up VSCode from that Cygwin shell where the OPAM environment settings are defined. Then VSCode and the OCaml extension should pick up your Merlin setup. So, I guess, the case is closed!
