ubuntu 14.04 安装vim YouCompleteMe自动补全插件 Linux C/C++高手必备
本文非常不适合Linux新手!
1,系统环境核对!
2,编译安装vim 8.0
3,获取YouCompleteMe,Vundle 软件包
-------------------------------
1,系统环境核对!
Ubuntu14.04.5LTS,64位 系统及内核版本: chunli@Linux:~$lsb_release-a NoLSBmodulesareavailable. DistributorID: Ubuntu Description: Ubuntu14.04.5LTS Release: 14.04 Codename: trusty chunli@Linux:~$uname-rm 4.4.0-31-genericx86_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-getinstallbuild-essential 2,安装依赖头文件和库 root@Linux:~#apt-getinstallpython-devpython3-dev 3,我的cmake版本太低 编译libclang需要高版本cmake3.4.3orhigher root@Linux:#apt-get-yautoremovecmake#卸载旧版本的cmake root@Linux:~#wgethttps://cmake.org/files/v3.8/cmake-3.8.0-rc2.tar.gz root@Linux:~#tarxfcmake-3.8.0-rc2.tar.gz root@Linux:~#cdcmake-3.8.0-rc2/ root@Linux:~/cmake-3.8.0-rc2#./bootstrap&&make&&makeinstall root@Linux:~/cmake-3.8.0-rc2#echo$? 0 检验cmake的安装 root@Linux:~/cmake-3.8.0-rc2#cmake bash:/usr/bin/cmake:没有那个文件或目录 找新的cmake路径 root@Linux:~/cmake-3.8.0-rc2#whichcmake /usr/local/bin/cmake 创建软链接 root@Linux:~/cmake-3.8.0-rc2#ln-s/usr/local/bin/cmake/usr/bin/cmake 查看现在cmake的版本 root@Linux:~/cmake-3.8.0-rc2#cmake--version cmakeversion3.8.0-rc2 这样编译工具就算完成了
编译安装vim 8.0
ubuntu 源码编译安装最新的vim 8.0
3,获取 YouCompleteMe,Vundle 软件包
root@Linux:~#gitclonehttps://github.com/Valloric/YouCompleteMe.git~/.vim/bundle/YouCompleteMe root@Linux:~#gitclonehttps://github.com/VundleVim/Vundle.vim.git~/.vim/bundle/Vundle.vim/bundle/Vundle root@Linux:~#vim~/.vimrc 添加以下行内容: filetypeoff setrtp+=~/.vim/bundle/Vundle.vim callvundle#begin() Plugin'VundleVim/Vundle.vim' Plugin'Valloric/YouCompleteMe' callvundle#end() filetypepluginindenton root@Linux:~# 安装vim插件 root@Linux:~#vim+PluginInstall+qall root@Linux:~#echo$? 0
下载编译安装 libclang 源代码
ThelibclanglibraryitprovidesisusedtopowertheYCMsemanticcompletionengineforthoselanguages. YCMisdesignedtoworkwithlibclangversion3.9orhigher. 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++,ObjectiveCandObjectiveC++前端 Compiler-RT主要是为Clang和LLVM提供运行时库的支持 root@Linux:~#wgethttp://releases.llvm.org/3.9.1/llvm-3.9.1.src.tar.xz root@Linux:~#wgethttp://releases.llvm.org/3.9.1/cfe-3.9.1.src.tar.xz root@Linux:~#wgethttp://releases.llvm.org/3.9.1/compiler-rt-3.9.1.src.tar.xz root@Linux:~#tarxfcfe-3.9.1.src.tar.xz root@Linux:~#tarxfllvm-3.9.1.src.tar.xz root@Linux:~#tarxfcompiler-rt-3.9.1.src.tar.xz root@Linux:~#mvcfe-3.9.1.srcllvm-3.9.1.src/tools/clang root@Linux:~#mvcompiler-rt-3.9.1.srcllvm-3.9.1.src/projects/compiler-rt root@Linux:~#mkdirbin root@Linux:~#cdbin/ 2,生成Makefile文件 root@Linux:~/bin#cmake-G"UnixMakefiles"../llvm-3.9.1.src root@Linux:~/bin#echo$? 0 3,编译并安装 root@Linux:~/bin#make&&makeinstall root@Linux:~/bin#echo$? 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-j8时,ld占用内存情况和ld程序的参数,大呼!
