这篇文章主要介绍ubuntu14.04如何安装vim YouCompleteMe自动补全插件，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
1, 系统环境核对!
Ubuntu 14.04.5 LTS, 64位 系统及内核版本: chunli@Linux:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.5 LTS Release: 14.04 Codename: trusty chunli@Linux:~$ uname -rm 4.4.0-31-generic x86_64 chunli@Linux:~$
环境不相符的, 就不要往下看了...
安装 系统编译工具,依赖头文件,库
1, 安装编译工具 root@Linux:~# apt-get install build-essential 2, 安装依赖头文件和库 root@Linux:~# apt-get install python-dev python3-dev 3, 我的cmake版本太低 编译libclang需要高版本cmake 3.4.3 or higher root@Linux:# apt-get -y autoremove cmake #卸载旧版本的cmake root@Linux:~# wget https://cmake.org/files/v3.8/cmake-3.8.0-rc2.tar.gz root@Linux:~# tar xf cmake-3.8.0-rc2.tar.gz root@Linux:~# cd cmake-3.8.0-rc2/ root@Linux:~/cmake-3.8.0-rc2# ./bootstrap && make && make install root@Linux:~/cmake-3.8.0-rc2# echo $? 0 检验cmake的安装 root@Linux:~/cmake-3.8.0-rc2# cmake bash: /usr/bin/cmake: 没有那个文件或目录 找新的cmake路径 root@Linux:~/cmake-3.8.0-rc2# which cmake /usr/local/bin/cmake 创建软链接 root@Linux:~/cmake-3.8.0-rc2# ln -s /usr/local/bin/cmake /usr/bin/cmake 查看现在cmake的版本 root@Linux:~/cmake-3.8.0-rc2# cmake --version cmake version 3.8.0-rc2 这样编译工具就算完成了
编译安装vim 8.0
3, 获取 YouCompleteMe,Vundle 软件包
root@Linux:~# git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe root@Linux:~# git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim/bundle/Vundle root@Linux:~# vim ~/.vimrc 添加以下行内容: filetype off set rtp+=~/.vim/bundle/Vundle.vim call vundle#begin() Plugin 'VundleVim/Vundle.vim' Plugin 'Valloric/YouCompleteMe' call vundle#end() filetype plugin indent on root@Linux:~# 安装vim 插件 root@Linux:~# vim +PluginInstall +qall root@Linux:~# echo $? 0
下载编译安装 libclang 源代码
The libclang library it provides is used to power the YCM semantic completion engine for those languages. YCM is designed to work with libclang version 3.9 or higher. 官方网站 http://releases.llvm.org/download.html 官方文档,值得看看:http://llvm.org/docs/GettingStarted.html#getting-started-quickly-a-summary clang 是llvm项目的 C, C++, Objective C and Objective C++ 前端 Compiler-RT 主要是为Clang和LLVM提供运行时库的支持 root@Linux:~# wget http://releases.llvm.org/3.9.1/llvm-3.9.1.src.tar.xz root@Linux:~# wget http://releases.llvm.org/3.9.1/cfe-3.9.1.src.tar.xz root@Linux:~# wget http://releases.llvm.org/3.9.1/compiler-rt-3.9.1.src.tar.xz root@Linux:~# tar xf cfe-3.9.1.src.tar.xz root@Linux:~# tar xf llvm-3.9.1.src.tar.xz root@Linux:~# tar xf compiler-rt-3.9.1.src.tar.xz root@Linux:~# mv cfe-3.9.1.src llvm-3.9.1.src/tools/clang root@Linux:~# mv compiler-rt-3.9.1.src llvm-3.9.1.src/projects/compiler-rt root@Linux:~# mkdir bin root@Linux:~# cd bin/ 2, 生成Makefile文件 root@Linux:~/bin# cmake -G "Unix Makefiles" ../llvm-3.9.1.src root@Linux:~/bin# echo $? 0 3, 编译并安装 root@Linux:~/bin# make && make install root@Linux:~/bin# echo $? 0 ---------------------------- [编译说明] (1), 此次 make 不指定多任务, 因为到后期连接库时,多任务导致内存溢出,内核会杀死ld进程 make 单进程,虽然慢了点,但是不会导致报错 文章尾部会贴上make -j 8时, ld 占用内存情况和 ld程序的参数, 大呼! (2), 磁盘空间必须足够大,你看看这家伙编译结束后,搞出来的包有多大! root@Linux:~# du -sh llvm-3.9.1.src 357M llvm-3.9.1.src root@Linux:~# du -sh bin/ 25G bin/ root@Linux:~# ----------------------------- 终于编译安装完了,晒晒编译耗时 root@Linux:~/bin# export HISTTIMEFORMAT="%F [%T] " root@Linux:~/bin# history | grep -A 8 'mkdir bin' 687 2017-03-04 [17:16:45] mkdir bin #开始准备 688 2017-03-04 [17:16:59] cd bin/ 689 2017-03-04 [17:17:31] cmake -G "Unix Makefiles" ../llvm-3.9.1.src 690 2017-03-04 [17:18:23] echo $? 691 2017-03-04 [17:19:01] make -j 8 && make install #后来报错,内存溢出 692 2017-03-04 [19:38:10] make && make install #马上更改单进程 693 2017-03-04 [20:24:17] echo $? #此时,编译完成 694 2017-03-04 [20:24:56] export HISTTIMEFORMAT="%F [%T] " 695 2017-03-04 [20:25:03] history ------------------------------------------ 测试clang root@Linux:~/bin# clang --help OVERVIEW: clang LLVM compiler USAGE: clang-3.9 [options] <inputs> 这样 clang 就算安装完成了 查找libclang.so安装路径,后面有用! root@Linux:/# find / -name '*libclang.so' /usr/local/lib/libclang.so /home/chunli/bin/lib/libclang.so
编译,配置YouCompleteMe
[说明] 我是Linux C程序员,需要使用C家族语法自动补全 使用我自定义的libclang.so -DEXTERNAL_LIBCLANG_PATH=/usr/local/lib/libclang.so [编译] root@Linux:~$ cd ~ root@Linux:~$ mkdir ycm_build root@Linux:~$ cd ycm_build root@Linux:~/ycm_build# cmake -G "Unix Makefiles" \ #开启命令换行模式 -DEXTERNAL_LIBCLANG_PATH=/usr/local/lib/libclang.so . \ ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp root@Linux:~/ycm_build# echo $? 0 root@Linux:~/ycm_build# cmake --build . --target ycm_core --config Release root@Linux:~/ycm_build# echo $? 0 配置YouCompleteMe root@Linux:~/ycm_build# cp ~/.vim/bundle/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/.vim/ chunli@Linux:~$ cat ~/.vimrc #添加两行 let g:ycm_server_python_interpreter='/usr/bin/python' let g:ycm_global_ycm_extra_conf='~/.vim/.ycm_extra_conf.py'
