[笔记]ubuntu 13.04 配置YouCompleteMe

参考 http://www.cnblogs.com/csuftzzk/p/3435710.html  但按照这篇文章，编译会出错，所以部分路径有修改，.vimrc配置略不同；

syntastic插件效果不理想，经常误报，还有就是比较卡。

一、 准备

1. 安装cmake, python-dev

sudo apt-get install cmake python-dev

2. 安装最新的VIM

sudo add-apt-repository ppa:nmi/vim-snapshotssudo apt-get updatesudo apt-get install vim

3. 下载Vundle, Vundle可以管理vim插件，很方便，更多可以参考 http://blog.csdn.net/codebistu/article/details/8257138

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

4. 下载完了vundle后，配置~/.vimrc文件如下，然后打开一个vim窗口，执行命令:BundleInstall， vundle会自动去网上将相关插件下载下来并安装好。要删除一个插件也很简单，先在~/.vimrc中移除该插件条目，然后进入vim执行命令:BundleClean。

set nocompatible              " be iMprovedBundle 'scrooloose/syntastic'set rtp+=~/.vim/bundle/vundle/call vundle#rc()" let Vundle manage Vundle" required!Bundle 'gmarik/vundle'" My bundles here:"" original repos on GitHubBundle 'tpope/vim-fugitive'Bundle 'Lokaltog/vim-easymotion'Bundle 'rstacruz/sparkup', {'rtp': 'vim/'}Bundle 'tpope/vim-rails.git'" vim-scripts reposBundle 'L9'Bundle 'FuzzyFinder'" non-GitHub reposBundle 'git://git.wincent.com/command-t.git'" Git repos on your local machine (i.e. when working on your own plugin)Bundle 'file:///Users/gmarik/path/to/plugin'" ...Bundle 'Valloric/YouCompleteMe'filetype plugin indent on     " required!

5. 编译LLVM+Clang的源代码

mkdir ~/llvmsrccd ~/llvmsrcsvn co http://llvm.org/svn/llvm-project/llvm/trunk llvmcd ~/llvmsrc/toolssvn co http://llvm.org/svn/llvm-project/cfe/trunk clangcd ~/llvmsrc/llvm/projectssvn co http://llvm.org/svn/llvm-project/compiler-rt/trunk compiler-rtsvn co http://llvm.org/svn/llvm-project/test-suite/trunk test-suitecd ~/llvmsrc./llvm/configure --enable-optimizedmake

二、配置，编译YouCompleteMe


1. 前面使用vundle已经下载好了YouCompleteMe的源码。


2. 编译

mkdir ~/ycm_buildcd ~/ycm_buildcmake -G "Unix Makefiles"  ~/.vim/bundle/YouCompleteMe/cpp -DEXTERNAL_LIBCLANG_PATH=~/llvmsrc/llvm/Release+Asserts/lib/libclang.somake ycm_coremake ycm_support_libs

3. 配置~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py。使用-isystem标志添加系统的头文件进行解析，而-I标志用于添加第三分的头文件进行解析。在flags最后增加如下：

'-isystem','/usr/include','-isystem','/usr/include/c++/','-isystem','/usr/include/i386-linux-gnu/c++'

4. 此外，为了更好的提高补全效率，我们可以保留原先使用的用Ctags生成的tags文件，并在~/.vimrc中添加：let g:ycm_collect_identifiers_from_tag_files = 1.其中，在vim中使用 :echo tagfiles()可以查看当前使用的tags文件。

5. 我的.vimrc配置内容：

" 去掉讨厌的有关vi一致性模式，避免以前版本的一些bug和局限set nocompatible" bundle setting au GUIEnter * call libcallnr("vimtweak.dll", "SetAlpha", 234)filetype off                  " required!set completeopt-=previewset rtp+=~/.vim/bundle/vundle/call vundle#rc()" let Vundle manage Vundle" required!
