Why does my Neovim instance fail to compile to the parsers?

[Jarmos-san]

I followed the official tutorials to install nvim-treesitter for Windows. Got MinGW toolsets installed, gcc is available on $PATH, everything appears to be fine, still Neovim fails to compile the parsers. I went through #1097 & #626 as well yet I still can't figure out what went wrong. So, any help to debug this issue further would be a godsend.

Besides, here's what :CheckHealth nvim_treesitter returns:

 ## Installation
 - WARNING: `tree-sitter` executable not found (parser generator, only needed for :TSInstallFromGrammar, not required for :TSInstall)
   - OK: `node` found v16.1.0 (only needed for :TSInstallFromGrammar)
   - OK: `git` executable found.
   - OK: `cc` executable found. Selected from { vim.NIL, "cc", "gcc", "clang", "cl" }
   - OK: Neovim was compiled with tree-sitter runtime ABI version 13 (required >=13). Parsers must be compatible with runtime ABI.

          +) multiple parsers found, only one will be used
          x) errors found in the query, try to run :TSUpdate {lang}

Wondering if I need to have the tree-sitter binary globally available on $PATH?

No Tree-Sitter binary is not needed for most parsers. If it is for a particular one you'll get notified.

What's the error message you're getting?

Have you tried the tips in the windows wiki (compiling with msvc or clang)?

Maybe we get the error output with TSInstallSync?

Oh interestingly, TSInstallSync python says the parsers are downloaded & installed but TSInstallInfo has something else to show.

Screenshots attached for further reference:

Is your gcc visible as cc in your PATH? Which console are you using that could eat up all errors? Can you try to compile the parsers manually? The command should be gcc -I./src src/parser src/scanner.cc -Os -shared -lstdc++ -o python.so

[theHamsta]

This looks also suspicious.

    if fn.has "win32" == 0 then
      table.insert(args, "-fPIC")
    end

Yeah sure I can try that & I'm using Windows PowerShell (the v5.x one). And I have to get some work done so I downloaded the parsers from the CI & used them.

I don't mind compiling the parsers manually & it's on my TODO list right now, so do give me some time to get back to it.
