I am trying to test the intellisense feature using this C++ snippet:

#include<iostream>
#include<string>

int main(void)
{
    std::string s;
    s.
    std::cout << "Hello!" << std::endl;
    return 0;
}

I expected that after typing s. on line number 7, the clangd coc.nvim extension gave me a rich list of possible methods from the std::string class. Actually I am not getting any suggestion. Why this?

sam-mccall commented 1 year ago

You're including standard library headers, maybe you don't have a standard library installed (in a standard place clang can find it)?

Are there any diagnostics shown? The log you posted didn't have any completion requests, was it truncated?

ricciolino commented 1 year ago

How can I tell clang where to search for the standard header files ? I am sure I have installed it because I can compile and run the code. The logs are not truncated, I don't know how to explicitly tell to coc plugin how to perform a completion request, I was thinking this could happen automatically once I start typing code similar to s. , expecting a request to take place in that moment, or am I wrong ?

Failed to find compilation database for /home/ricciolino/Desktop/tmp/test_c++/main.cpp

clangd needs compile_commands.json to understand your code, https://clangd.llvm.org/installation#project-setup

ricciolino commented 1 year ago

Here is my ~/.vim/coc-settings.json:

{
    "python.pythonPath": "python",
    "python.autoComplete.addBrackets": true,
    "python.formatting.provider": "autopep8",
    "clangd.path": "/usr/bin/clangd",
    "clangd.arguments": [
        "-I/usr/include/c++/11",
        "-I/usr/local/include"
    ]
}

Here is my compile_commands.json:

[
  {
    "directory": "/home/ricciolino/Desktop/tmp/test_c++",
    "file": "/home/ricciolino/Desktop/tmp/test_c++/main.cpp",
    "command": "g++ -std=c++11 -o /home/ricciolino/Desktop/tmp/test_c++/main /home/ricciolino/Desktop/tmp/test_c++/main.cpp"
  }
]

Now I am getting this error when open file main.cpp:

[coc.nvim] Server clangd failed to start: Error: Pending response rejected since connection got
[coc.nvim] clangd client: couldn't create connection to server.

Here is the output of :CocOpenLog:

Your clangd failed to start. You've set clangd.path in coc-settings.json, what's the output of /usr/bin/clangd --version?

ricciolino commented 1 year ago 
> /usr/bin/clangd --version
Ubuntu clangd version 14.0.0-1ubuntu1
Features: linux+grpc
Platform: x86_64-pc-linux-gnu

I installed clangd using apt package manager (Ubuntu 22), I also tried installing it from inside Vim editor using :CocCommand clangd.install command, but same error persist.

fannheyward commented 1 year ago

Set clangd.path to ~/.config/coc/extensions/coc-clangd-data/install/16.0.2/clangd_16.0.2/bin/clangd and try again.

ricciolino commented 1 year ago

I already did it, same error occurs.

fannheyward commented 1 year ago
  1. remove clangd.path from your coc-settings.json
  2. remove ~/.config/coc/extensions/coc-clangd-data
  3. open an C/C++ file, run :CocCommand clangd.install to re-install clangd
ricciolino commented 1 year ago

Just done all three steps. Same error occur. Here is the Log:

From your first logs, https://github.com/clangd/coc-clangd/issues/603#issue-1801101819, clangd runs as expected, but now clangd failed to start.

~/.config/coc/extensions/coc-clangd-data/install/16.0.2/clangd_16.0.2/bin/clangd --version ok?

Make sure you're using the correct clangd.

" ~/.config/coc/extensions/coc-clangd-data/install/16.0.2/clangd_16.0.2/bin/clangd --version ok? " Yes it's ok:

> ~/.config/coc/extensions/coc-clangd-data/install/16.0.2/clangd_16.0.2/bin/clangd --version
clangd version 16.0.2 (https://github.com/llvm/llvm-project 18ddebe1a1a9bde349441631365f0472e9693520)
Features: linux+grpc
Platform: x86_64-unknown-linux-gnu

Yeah from my first comment clangd was ok because I didn't have these lines added to coc-settings.json file:

    "clangd.arguments": [
        "-I/usr/include/c++/11",
        "-I/usr/local/include"
    ]

Removing those lines, I have a clean Log when open a cpp file:

2023-07-13T11:56:57.632 INFO (pid:1614357) [plugin] - coc.nvim initialized with node: v18.16.1 after 88

But still see errors of this kind: • 'iostream' file not found (clang pp_file_not_found) • Use of undeclared identifier 'std' (clang undeclared_var_use)

clangd.arguments is args passed to clangd, something like --background-index, check clangd --help. You can't pass includes to this.

Remove the clangd.arguments configurations, and setup compile_commands.json for your project.

Close for now because isn't coc-clangd's issue.

ricciolino commented 1 year ago

I configured now compile_commands.json like this:

"command": "g++ -std=c++11 -I/usr/local/include -I/usr/include/c++/11 -o /home/ricciolino/Desktop/tmp/test_c++/main /home/ricciolino/Desktop/tmp/test_c++/main.cpp"

And coc-settings.json like this:

    "clangd.path": "~/.config/coc/extensions/coc-clangd-data/install/16.0.2/clangd_16.0.2/bin/clangd",
    "clangd.arguments": [
        "--background-index",
        "--completion-style=detailed",
        "--header-insertion=iwyu",
        "--suggest-missing-includes"
    ]

Still no lucky, it doesn not work.

fannheyward commented 1 year ago

How do you generate compile_commands.json? You can use bear to generate it. https://clangd.llvm.org/installation#project-setup

https://clang.llvm.org/docs/JSONCompilationDatabase.html

ricciolino commented 1 year ago

Now I tried to generate using bear:

bear -- g++ -std=c++11 -I/usr/local/include -I/usr/include/c++/11 -o /home/ricciolino/Desktop/tmp/test_c++/main /home/ricciolino/Desktop/tmp/test_c++/main.cpp

And the generated compile_command.json is this one:

> cat compile_commands.json 
[
  {
    "arguments": [
      "/usr/bin/g++",
      "-c",
      "-std=c++11",
      "-I/usr/local/include",
      "-I/usr/include/c++/11",
      "-o",
      "/home/ricciolino/Desktop/tmp/test_c++/main",
      "/home/ricciolino/Desktop/tmp/test_c++/main.cpp"
    ],
    "directory": "/home/ricciolino/Desktop/tmp/test_c++",
    "file": "/home/ricciolino/Desktop/tmp/test_c++/main.cpp",
    "output": "/home/ricciolino/Desktop/tmp/test_c++/main"
  }
]

But opening main.cpp still error messages appear.

@sam-mccall can you take a look?

ricciolino commented 1 year ago

Hey guys! I think I solved !!!! I just realized that I was missing this "include" path: /usr/include/x86_64-linux-gnu/c++/11

So I re-run bear for generating the compile_commands.json file like this: bear -- g++ -std=c++11 -I/usr/local/include -I/usr/include/c++/11 -I/usr/include/x86_64-linux-gnu/c++/11 -o /home/ricciolino/Desktop/tmp/test_c++/main /home/ricciolino/Desktop/tmp/test_c++/main.cpp

And now the autocomplete suggestions work as expected (I think :) ): image
