Ubuntu16.04 Installing Youcompleteme Auto-complete plug-in

Recently, the VMware workstation has been ruined, the virtual machines inside are not open. After the reload after a few days or the same old, simply installed VirtualBox to play.

The first thing is to install the Vim plug-in, make this thing is exhausted, especially install youcompleteme, so the process recorded down here to share.

One installation VIM8.0

First, install vim directly on the Ubuntu16.04

1 sudo apt-get install vim

At this time the installed vim default is 7.4 version, enter the following instructions can be upgraded (Ubuntu can only):

1 sudo add-apt-repository ppa:jonathonf/vim2sudo apt update3 sudo apt Install Vim

After the installation is complete, you can view the following commands:

Vim--version

Now you can see the text message and display your vim version number.

or enter the command vim, you can see the following interface:

Second, installation Vundle

because VIM lacks the default plug-in Manager, all the plug-in files are scattered in several folders under ~/.vim, which causes the installation, update and deletion of various plugins to be handled manually, both troublesome and possible errors. So we need plug-in manager to help, common plugins manager has vundle, pathogen and so on, we use vundle here.

1. Download the Vundle to the ~/.vim/bundle/vundle directory

Vundle is hosted on Github, so use git to download Vundle and store it in ~/.vim/bundle/vundle. Check out the source code directly to the directory using the following command:　　

1 git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle 

2. Configure the. vimrc file

Go to the ~ directory and use Ls-al to view the hidden file, if the. vimrc file does not exist, then create it.

First make the following configuration (in order to quickly install, only installed Vundle management plug-in, syntax highlighting plug-ins, auto-complete plug-ins, other plugins can be installed at any time):

1 filetype off2 Setrtp+=~/.vim/bundle/Vundle3 4 Call Vundle#begin ()5 6 7 "to have vundle manage the plug-in version, you must8Bundle'Vundlevim/vundle.vim'9 Ten  OneBundle'Tomasr/molokai' ABundle'Valloric/youcompleteme' -  -Call Vundle#end ()"must be theFileType plugin indent on"vim must be loaded with the appropriate syntax and file type related scripts for the plugin

Save exit, enter the VIM directive, and then : Bundleinstall can install the plugin, for example.

Done after execution :

Tips: Because the youcompleteme is relatively large, so you have to wait for a while, do not have to do before the forced exit, or it will cause the file download is not complete.

Third, compiling ycm_core.so and libclang.so

1. The first thing to install CMake is to compile:

1 sudo apt-get install CMake

Tips

During compilation, if the following error occurs:

The workaround for this error is to install Python-dev, which is a Python header file and a static library package.

1 sudo apt-get install Python-dev

After the execution is complete, the compilation will succeed.

2. Then go to the Youcompleteme folder and compile the. sh file first, as follows

1 $ cd ~/.vim/bundle/youcompleteme23 $./install.sh--clang-completer

3. Then compile the. py file:

1 ./install.py--clang-completer

Compile successfully.

Four, the final configuration

1. Go to the ~/.vim/bundle/youcompleteme/third_party/ycmd folder and enter LS *.so* to see if the following link files are available, indicating that the compilation above is successful.

2. Enter the following command to copy a. ycm_extra_conf.py:

1 cd ~/.vim/bundle/youcompleteme/2 CP./third_party/ycmd/examples/.ycm_extra_conf.py ~/.vim/

3. Edit the. vimrc file, and add a line below the previous filetype plugin indent on :

1 let g:ycm_global_ycm_extra_conf='~/.vim/bundle/youcompleteme/third_party/ycmd/cpp/ycm/. ycm_extra_conf.py'

4. Complete configuration.

Enter . ycm_extra_conf.py file, add the following lines to a bunch of things:

Attention! Attention! Attention!

82 and 84 lines of the digital version number, to go into the/usr/include/c++/under their own to see, may be slightly different.

At this point, our Youcompleteme auto-complete plug-in installation is successful!
