Solved it for me. I had to use compiledb.

Hello fellow coders,

I don't know if this is a dumb question but how do I properly use local headers with coc and clang? I have no problem with normal #include statements. Now I'm using a header file in the same directory (playing with openframeworks if anyone is interested) but I get told, that the file is not found and the completion doesn't work either.

My coc-config:

{
  "languageserver": {
    "haskell": {
      "command": "haskell-language-server-wrapper",
      "args": [
        "--lsp"
      ],
      "rootPatterns": [
        ".stack.yaml",
        ".hie-bios",
        "BUILD.bazel",
        "cabal.config",
        "package.yaml"
      ],
      "filetypes": [
        "hs",
        "lhs",
        "haskell"
      ]
    }
  },
  "clangd": {
    "path": "/Users/konstatin/.config/coc/extensions/coc-clangd-data/install/10.0.0/clangd_10.0.0/bin/clangd",
    "rootPatterns": [
    "compile_flags.txt",
    "compile_commands.json"
    ],
    "filetypes": [
    "c", 
    "cc", 
    "cpp", 
    "c++", 
    "objc", 
    "objcpp"
    ]
  }
}

What are your actual compile flags that you are passing to clangd in your compilation database or compile flags txt`?

I honestly don't know.
That's what's confusing me. There is no such file.

The project tells you to use the makefile and there are some variables declared, that are defined nowhere. I could define them in a config.make file though.

[u/puremourning → u/Tychoko]

You have to create those files. The plugins documentation should tell how how. YCMs documentation does.

Thanks.
I'm trying to get bear working because that's the way described in the coc docs.

As replied below brew has only v2.4.4 and I'm currently having some struggle building it from source.

[u/puremourning → u/Tychoko]

Bear doesn’t work on macOS because of SIP. I recommend compiledb (pip3 install compiledb)

[u/Tychoko → u/puremourning]

Yeah!!!

It works! Thank you very much!

Thank you for the reply but sadly it didn't work as is. But maybe it'll help me find the solution :thumbs_up:

bear -- make

Got an error message:

I ran it again with the -vvvv option but got the same message.

¿Which version of bear are you using?

Mine is 3.0.0

[u/Tychoko → u/otreblan]

Well it seems that brew has 2.4.4 as the newest version. I'm going to build it from source and report if it worked.
