Mac安装YouCompleteMe插件

参考：http://valloric.github.io/YouCompleteMe/

http://blog.marchtea.com/archives/161

一,安装准备：

1,Vim版本7.3.584+编译时添加+python标识

//安装python-dev2.7mac默认已安装

命令行vim—version查看vim版本或进入vim后输入:version

查看是否支持python:echohas('python')输出1表示支持输入0则否

Mac通过brewinstallvim安装最新的7.4版本的vim:/usr/local/Cellar/vim/7.4.335/bin

在~/.bash_profile添加：exportPATH=/usr/local/Cellar/vim/7.4.335/bin:$PATH

2,安装cmake

查看whichcmake是否已安装，http://www.cmake.org下载cmake-2.6.4.tar.gz

tar-xzvfcmake-2.6.4.tar.gz

cdcmake-2.6.4

./bootstrap

make

makeinstall

3,下载clangbinary版本3.2以上版本官网http://clang.llvm.org

将clang+llvm-3.3-x86_64-apple-darwin12.tar解压到~/ycm_temp/llvm_root_dir目录

//~/ycm_temp/llvm_root_dir(withbin,lib,includeetc.rightinsidethatfolder)

4，安装vundle插件利用vundle安装YCM插件

$gitclonehttps://github.com/gmarik/Vundle.vim.git~/.vim/bundle/Vundle.vim

配置~/.vimrc参考：http://valloric.github.io/YouCompleteMe/

二，安装

1，执行vim+PluginInstall+qall让vundle把YCM插件下载到本地，网速慢等待比较久

YCM下载到~/.vim/bundle之后，开始编译YCM

-->cd~&&mkdirycm_build

-->cdycm_build

-->cmake-G"UnixMakefiles"-DPATH_TO_LLVM_ROOT=~/ycm_temp/llvm_root_dir.~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp//注意llvm_root_dir.~/

-->makeycm_support_libs

-->make

//itwillalsoplacethelibclang.[so|dylib]intheYouCompleteMe/pythonfolderforyouifyoucompiledwithclangsupport(itneedstobethereforYCMtowork).

如果没提示报错，则安装编译成功

2，配置

YCMlooksfora.ycm_extra_conf.pyfileinthedirectoryoftheopenedfileorinanydirectoryaboveitinthehierarchy(recursively);

Don'tjustcopy/pastethatfilesomewhereandexpectthingstomagicallywork;

yourprojectneedsdifferentflags.

nnoremap<leader>gg:YcmCompleterGoToDefinitionElseDeclaration<CR>

nnoremap<F5>:YcmForceCompileAndDiagnostics<CR>

YCM提供的跳跃功能采用了vim的jumplist,往前跳和往后跳的快捷键为Ctrl+O以及Ctrl+I.

问题：找不到STL相关定义：

解决方法：

callecho|clang-v-E-xc++-andlookatthepathsunderthe#include<...>searchstartshere:heading.

Youshouldtakethosepaths,prepend-isystemtoeachindividualpathandappendthemalltothelistofflagsinyour.ycm_extra_conf.pyfile.

将flags一些无用的-I-isystem需要清理掉.

stringstr;需要std::stringstr；才会补全。

.ycm_extra_conf.py文件一览：

flags=[]中的路径根据具体情况配置

~/根路径放置一个fallbackycm_extra_conf.py

然后在每个项目路径放置一个各自的ycm_extra_conf.py
