Project is compiling fine but YCM is displaying errors #3666

Closed smadurange closed 4 years ago

smadurange commented 4 years ago

I'm getting YCM warnings that doesn't seem to be caused by real issues. I'm a beginner, so I apologise if this is a trivial issue. But I could not find a fix myself for this.

Thank you for adhering to this process! It ensures your issue is resolved quickly and that neither your nor our time is needlessly wasted.

Issue Details

I'm getting following errors when I'm using std::mutex and spdlog libraries:

With std::mutex:

Call to deleted constructor of 'std::mutex'                                                 
/../lib64/gcc/x86_64-pc-linux-gnu/9.3.0/../../../../include/c++/9.3.0/bits/std_mutex.h:94:5:
note: 'mutex' has been explicitly marked deleted here

With spdlog::trace("Hello%d", 1) I get:

No matching function for call to 'trace'                                                    
/usr/include/spdlog/spdlog.h:187:13:
note: candidate function template not viable: requires single argument 'msg', but 2 arguments were provided

Note that spdlog issue only happens when I use string formatting with %s or %d. When I just do something like spdlog::info("Hello") I do not get any errors from YCM.

I installed spdlog using pacman (I'm on Arch Linux x64) and I'm using CMake and Ninja to build the project with clang compiler. My .vimrc file:

" General configuration options
 set number
 set encoding=utf-8
 syntax on

" YouCompleteMe
" clangd-based completer for YouCompleteMe
let g:ycm_clangd_binary_path="/usr/bin/clangd"
let g:ycm_global_ycm_extra_conf="/home/sadeep/.vim/pack/YouCompleteMe/third_party/ycmd/.ycm_extra_conf.py"
set runtimepath+=~/.vim/pack/YouCompleteMe/

" Indentation
filetype plugin indent on
set tabstop=4
set shiftwidth=4
set expandtab

Minimal example: Test.hpp:

#pragma once

#include <mutex>
#include <boost/asio.hpp>
#include <boost/asio/ip/tcp.hpp>
#include <spdlog/spdlog.h>

using boost::asio::ip::tcp;

class Test
{
   public:
         Test() : mtx(std::mutex())
         {
               spdlog::trace("Hello, world%d!", 2);
         }
  private:
        std::mutex mtx;
};

And in main.cpp, I just import this:

#include "Test.hpp"
int main(int argc, char *argv[])
{
      Test t;
       return 0;
}

CMakeLists.txt:

cmake_minimum_required(VERSION 3.16)

project(Test LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread")

add_executable(test
     main.cpp
     Test.hpp
)

find_package(spdlog REQUIRED)
target_link_libraries(cmail spdlog::spdlog)

Test.hpp|6 col 10 error| In included file: 'spdlog/fmt/bundled/core.h' file not found /usr/include/spdlog/    fmt/fmt.h:22:10: note: error occurred here [pp_file_not_found]

Arch package doesn't contain /usr/include/spdlog/fmt/bundled. That seems to be the fmt library, so install it properly and use the proper include paths. Or clone the entire spdlog locally.

Test.hpp|13 col 14 error| Call to deleted constructor of 'std::mutex' /../lib64/gcc/x86_64-pc-linux-gnu/9.    3.0/../../../../include/c++/9.3.0/bits/std_mutex.h:94:5: note: 'mutex' has been explicitly marked deleted

The copy constructor of std::mutex is indeed deleted.

  Test.hpp|15 col 9 error| No matching function for call to 'trace' /usr/include/spdlog/spdlog.h:187:13: not    e: candidate function template not viable: requires single argument 'msg', but 2 arguments were provided [    ovl_no_viable_function_in_call]

There are 3 overloads of trace(). Two of which take something called string_view_t which is [fmt::string_basic_string_view<char](using string_view_t = fmt::basic_string_view;). Again, you will need fmt library in order to make this work.

 

Also, your project isn't producing a compile_command.json and you're loading .ycm_extra_conf.py, rendering the provided CMakeLists.txt irrelevant. Your flags say that you're using -std=c++11.

smadurange commented 4 years ago

@bstaletic Thanks for the explanation specially about the flags. Managed to fix some other issues I had thanks to that too. I updated .ycm_extra_conf.py to be similar to my cmake definition.

Also, you are right about the spdlog issue. Thanks!

You're welcome. For user support prefer gitter over github issues.
