手把手教你配置linux下C++开发工具——vim+ycm(YouCompleteMe),支持基于语义的自动补全和第三方库补全(史上最简单、史上最透彻、史上最全的终极解决方案)

截止到目前,vim稳定版本已经到了8.2+,ycm(YouCompleteMe的简称)最新版本与几年前的安装配置截然不同了。之前网上很多教程也教不得法,生搬硬套,没有讲透彻。所以,才下定决心写一篇自认为史上最简单、史上最全的教程出来。

一、准备工作

       1、安装python(ycm需要使用python3.6以上的版本,这里选择python3.8.5):

                   1.1、进入download目录:cd download

                   1.2、下载python3.8.5:wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tar.xz

                   1.3、解压: xz -d Python-3.8.5.tar.xz  && tar -xvf Python-3.8.5.tar

                   1.4、进入Python-3.8.5目录:cd Python-3.8.5

                   1.5、配置:./configure –prefix=/usr –enable-shared –enable-optimizations –with-ssl

                   1.6、构建及安装:make -j 8 && sudo make install   #构建完成后,会安装在/usr/bin目录

                   1.7、测试:在命令行输入python –version或python3 –version

二、安装vim8.2+

            1、下载vim8.2:git clone https://github.com/vim/vim.git

            2、进入目录:cd vim

            3、切换到最新的tag:git checkout v8.2.1522    #可使用git tag查看所有的tag

            4、配置:./configure –prefix=/usr –enable-luainterp=yes –enable-mzschemeinterp –enable-perlinterp=yes  –enable-python3interp=yes –enable-tclinterp=yes –enable-rubyinterp=yes –enable-cscope –enable-terminal –enable-autoservername –enable-multibyte –enable-xim –enable-fontset –with-modified-by=shlian –with-compiledby=shlian  –with-python3-command=python3   

           如果上述配置命令配置、编译后,vim一直不能支持python3,则建议尝试一下下面的命令:

            ./configure –prefix=/usr –enable-luainterp=yes –enable-mzschemeinterp –enable-perlinterp=yes  –enable-python3interp=yes –enable-tclinterp=yes –enable-rubyinterp=yes –enable-cscope –enable-terminal –enable-autoservername –enable-multibyte –enable-xim –enable-fontset –with-modified-by=shlian –with-compiledby=shlian  –with-python3-config-dir=/usr/lib/python3.8/config-3.8-x86_64-linux-gnu

           #上面的–with-python3-config-dir的目录视机器的不同而不同,建议在自己的机器上查找具体的配置目录并修改。

           说明:

              1、标红的非常关键, vim8.2以后的版本,在配置的时候,不用再指定python的config目录了(网上很多很多指定python的config目录的教程,只能说已经过时了,详见:./configure –help)

              2、注意:vim8.2不支持同时使用python2和python3,所以千成不可以在上述命令中指定:–enable-pythoninterp=yes,否则python3不会被vim支持的

              3、如果发现了错误,则安装不存在的依赖包:

                     3.1 yum install perl-devel #让vim支持perl解释器

                     3.2 yum install perl-ExtUtils-Embed #安装包解决:找不到EXTERN.h文件的问题

                     3.3 yum install ruby-devel #让vim支持ruby解释器

                     3.4 如果系统已经有自带的python3.6及以上版本了,建议先安装一下python3-devel(ubuntu:sudo apt-get install python3-dev)

               5、构建及安装:make -j 8 && sudo make install

               6、查看vim是否支持python3:

                 手把手教你配置linux下C++开发工具——vim+ycm(YouCompleteMe),支持基于语义的自动补全和第三方库补全(史上最简单、史上最透彻、史上最全的终极解决方案)

                 带+号的说明已经支持了,所以,已经成功安装了支持python3的vim

 

三、安装vim辅助插件

            1、下载管理插件的插件——vundle

                 新建目录: mkdir -p  ~/.vim/bundle

                 clone代码:git clone https://github.com/VundleVim/Vundle.vim.git  ~/.vim/bundle/Vundle.vim

              2、在home目录,新建一个.vimrc文件,并输入以下内容:                   

set nocompatible              " be iMproved, required
filetype off                  " required
 
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
 
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
 
" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required

               3、安装

                    使用vim打开.vimrc文件 : vim .vimrc 

                    按键”shift+;”进入命令模式,输入:PluginInstall,然后回车即可完成安装

               4、配置.vimrc,是一项很复杂的工作,我配置好的如下(已经安装了很多插件了,如:文件搜索、注释、doxygen、drawit、buffer、winmanager+taglist+tagbar等等):

保存后,重新打开vim,执行 vundle的安装命令:PluginInstall,如下图所示:

       手把手教你配置linux下C++开发工具——vim+ycm(YouCompleteMe),支持基于语义的自动补全和第三方库补全(史上最简单、史上最透彻、史上最全的终极解决方案)

   至此,完成了vim常用插件的安装,接入来安装号称最复杂的插件ycm。

四、安装和配置ycm

           1、进入插件目录:cd ~/.vim/bundle

            2、下载ycm:git clone https://github.com/ycm-core/YouCompleteMe.git

            3、更新依赖模块:git submodule update –init –recursive

            4、安装:./install.py –clangd-completer   # –all  安装所有支持的补全(目前最新版本的YCM已经不需要额外下载llvm+clang来编译了),编译完成后的结果如下图所示:

手把手教你配置linux下C++开发工具——vim+ycm(YouCompleteMe),支持基于语义的自动补全和第三方库补全(史上最简单、史上最透彻、史上最全的终极解决方案)

比以前方便了很多,clang已经放到了.vim/bundle/YouCompleteMe/third_party/ycmd/third_party/clangd/output/bin目录了,并且已经启用了,不需要再配置复杂的.ycm_extra_conf.py文件了

关于YCM的说明、配置都在:https://github.com/ycm-core/YouCompleteMe#c-family-semantic-completion

你可以找到任何关于ycm的信息,不过可能需要花一点时间。

               5、在vim中安装ycm插件:

                       打开.vimrc文件,找到”Plugin ‘Valloric/YouCompleteMe’  #把前面的”删除,然后重新安装:PluginInstall

               6、打开的时候可能会报错:

                     1、YouCompleteMe unavailable: unable to load Python.

                       解决办法:sudo yum install vim-gtk-syntax    安装完成后,重新启动vim即可解决(如果解决不了请联系我)

                     2、找不到ctags

                       解决办法:sudo yum install ctags

                     3、_socket.cpython-38-x86_64-linux-gnu.so: undefined symbol: PyFloat_Type

                      分析:这不是vim的问题,也不是ycm的问题,而是python的问题,在命令行运行python3,然后import ctypes必然会报错。

                      解决办法:

                                    1、安装:yum install libffi-devel gcc gcc-c++ zlib zlib-devel readline-devel openssl-devel bzip2-devel sqlite-devel

                                    2、返回第一步,重新安装python,在命令行打开python3,然后import ctypes  #如果不报错,那就解决了。

       至此,ycm插件安装完成了,比前几年安装简单太多了。

      其实,到这一步,如果没有错误的话,vim+ycm已经可以支持代码补全了(只是部分的补全哟,目前还补全不了c++工程中的基础库、依赖的第三方库,如:boost、libevent等)

 

五、让vim支持语议补全——补全工程上下文、补全第三方依赖库

        1、介绍一下ycm补全的实现及功能:YCM的补全功能,使用的是clangd(clangd与libclang完全不同,请自行百度)的基于语义分析来进行补全的,如下文:

              

Advantages of clangd over libclang include:
1、Project wide indexing: Clangd has both dynamic and static index support. The dynamic index stores up-to-date symbols coming from any files you are currently editing, whereas static index contains project-wide symbol information. This symbol information is used for code completion and code navigation. Whereas libclang is limited to the current translation unit(TU).
2、Code navigation: Clangd provides all the GoTo requests libclang provides and it improves those using the above mentioned index information to contain project-wide information rather than just the current TU.
Rename: Clangd can perform semantic rename operations on the current file, whereas libclang doesn’t support such functionality.
3、Code Completion: Clangd can perform code completions at a lower latency than libclang; also, it has information about all the symbols in your project so it can suggest items outside your current TU and also provides proper #include insertions for those items.
Signature help: Clangd provides signature help so that you can see the names and types of arguments when calling functions.
4、Format Code: Clangd provides code formatting either for the selected lines or the whole file, whereas libclang doesn’t have such functionality.
Performance: Clangd has faster reparse and code completion times compared to libclang.
In order to perform semantic analysis such as code completion, GoTo and diagnostics, YouCompleteMe uses clangd, which makes use of clang compiler, sometimes also referred to as llvm. Like any compiler, clang also requires a set of compile flags in order to parse your code. Simply put: If clang can't parse your code, YouCompleteMe can't provide semantic analysis.

        上文中最后一句:Simply put: If clang can’t parse your code, YouCompleteMe can’t provide semantic analysis.非常重要,如果clangd不能分析你的代码,YCM就不能提供基于语议的补全

当安装了vim(+python3)+YCM+clangd时,使用vim打开工程的.h、.cpp时,clangd会根据打开的文件进行语议猜测,然后进行提示,但是,猜测”一般是不可靠的所以:

There are 2 methods which can be used to provide compile flags to clang:
Option 1: Use a compilation database
The easiest way to get YCM to compile your code is to use a compilation database. A compilation database is usually generated by your build system (e.g. CMake) and contains the compiler invocation for each compilation unit in your project.
For information on how to generate a compilation database, see the clang documentation. In short:
If using CMake, add -DCMAKE_EXPORT_COMPILE_COMMANDS=ON when configuring (or add set( CMAKE_EXPORT_COMPILE_COMMANDS ON ) to CMakeLists.txt) and copy or symlink the generated database to the root of your project.
If using Ninja, check out the compdb tool (-t compdb) in its docs.
If using GNU make, check out compiledb or Bear.
For other build systems, check out .ycm_extra_conf.py below.
If no .ycm_extra_conf.py is found, YouCompleteMe automatically tries to load a compilation database if there is one.
YCM looks for a file named compile_commands.json in the directory of the opened file or in any directory above it in the hierarchy (recursively); when the file is found before a local .ycm_extra_conf.py, YouCompleteMe stops searching the directories and lets clangd take over and handle the flags.

clangd支持多种生成”补全数据库“的方式,如上面提到的,基于cmake、Ninja、GNU make;

如果使用的是cmake的构建方式,则有两种生成”补全数据库“的方式:

第一种:在工程根目录执行:cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 -DCMAKE_BUILD_TYPE=Debug

              执行完成后,就会在工程根目录生成“compile_commands.json”文件。

              然后使用vim重新打开工程中的文件(只要你的CMakeLists.txt配置正确),就不会报找不到第三库、依赖库的错误了

第二种:在工程的顶层CMakeLists.txt中,增加配置:set( CMAKE_EXPORT_COMPILE_COMMANDS ON )

               即可在reload 或构建的时候,自动生成compile_commands.json文件”

*********************本人选用的是第二种模式,构建的时候会自动生成compile_commands.json文件。********************

更详细的请参见:

1、http://clangd.llvm.org/installation.html

2、https://github.com/ycm-core/YouCompleteMe#c-family-semantic-completion

如果没有使用CMake、Ninja、GNU Make,则需要使用.ycm_extra_conf.py文件配置flags了,(曾经配置过,个人不建议使用这种方法,并且效率也不高,在ycm官网的文档中有说明,所以不作介绍了)

Option 2: Provide the flags manually
If you don't have a compilation database, or aren't able to generate one, you have to tell YouCompleteMe how to compile your code some other way.
Every C-family project is different. It is not possible for YCM to guess what compiler flags to supply for your project. Fortunately, YCM provides a mechanism for you to generate the flags for a particular file with arbitrary complexity. This is achieved by requiring you to provide a Python module which implements a trivial function which, given the file name as argument, returns a list of compiler flags to use to compile that file.
YCM looks for a .ycm_extra_conf.py file in the directory of the opened file or in any directory above it in the hierarchy (recursively); when the file is found, it is loaded (only once!) as a Python module. YCM calls a Settings method in that module which should provide it with the information necessary to compile the current file. You can also provide a path to a global configuration file with the g:ycm_global_ycm_extra_conf option, which will be used as a fallback. To prevent the execution of malicious code from a file you didn't write YCM will ask you once per .ycm_extra_conf.py if it is safe to load. This can be disabled and you can white-/blacklist files. See the g:ycm_confirm_extra_conf and g:ycm_extra_conf_globlist options respectively.
This system was designed this way so that the user can perform any arbitrary sequence of operations to produce a list of compilation flags YCM should hand to Clang.
NOTE: It is highly recommended to include -x <language> flag to libclang. This is so that the correct language is detected, particularly for header files. Common values are -x c for C, -x c++ for C++, -x objc for Objective-C, and -x cuda for CUDA.
To give you an impression, if your C++ project is trivial, and your usual compilation command is: g++ -Wall -Wextra -Werror -o FILE.o FILE.cc, then the following .ycm_extra_conf.py is enough to get semantic analysis from YouCompleteMe:
def Settings( **kwargs ):
return {
'flags': [ '-x', 'c++', '-Wall', '-Wextra', '-Werror' ],
}
As you can see from the trivial example, YCM calls the Settings method which returns a dictionary with a single element 'flags'. This element is a list of compiler flags to pass to libclang for the current file. The absolute path of that file is accessible under the filename key of the kwargs dictionary. That's it! This is actually enough for most projects, but for complex projects it is not uncommon to integrate directly with an existing build system using the full power of the Python language.
For a more elaborate example, see ycmd's own .ycm_extra_conf.py. You should be able to use it as a starting point. Don't just copy/paste that file somewhere and expect things to magically work; your project needs different flags. Hint: just replace the strings in the flags variable with compilation flags necessary for your project. That should be enough for 99% of projects.
You could also consider using YCM-Generator to generate the ycm_extra_conf.py file.
Errors during compilation
If Clang encounters errors when compiling the header files that your file includes, then it's probably going to take a long time to get completions. When the completion menu finally appears, it's going to have a large number of unrelated completion strings (type/function names that are not actually members). This is because Clang fails to build a precompiled preamble for your file if there are any errors in the included headers and that preamble is key to getting fast completions.
Call the :YcmDiags command to see if any errors or warnings were detected in your file.

八、可能遇到的问题及解决方案

            1、启动的时候报错:Taglist: Exuberant ctags (http://ctags.sf.net) not found in PATH. Plugin is not loaded.

                  解决方案:安装ctags(yum install ctags或apt-get install ctags)

            2、Cannot set language to “zh_CN.UTF-8”

                  需要修改vimrc的配置或把linux的locate修改为zh_CN.utf-8(sudo vim /etc/default/locate )
