使用vim+cscope組合，搭建編程環境

 1. Download the latest vim version and build it as follows steps:

./configure --prefix=/home/tools                   //安裝目錄
--enable-perlinterp                                //perl整合
--enable-pythoninterp                              //python整合
--enable-cscope                                    //csope支援
--enable-multibyte                                 //雙位元組支援，一次可以跳過一個漢字
--enable-fontset                                         
--with-features=huge                               //最大特性

make
make install

2. taglist support
download taglist plugin (taglist_45.zip)

3. cscope support
download cscope-15.7.tar.bz2
./configure && make && make install

4. cscope.files generation for linux kernel

#! /bin/sh
LNX=$PWD
cd /     
find  $LNX                                                                /
    -path "$LNX/arch/*" ! -path "$LNX/arch/arm*" -prune -o               /
    -path "$LNX/include/asm-*" ! -path "$LNX/include/asm-arm*" -prune -o /
    -path "$LNX/tmp*" -prune -o
/
    -path "$LNX/Documentation*" -prune -o
/
    -path "$LNX/scripts*" -prune -o
/
    -path "$LNX/drivers*" -prune -o
/
        -name "*.[chxsS]" -print > $LNX/cscope.files

Now, I don't use above shell script, just use following commands:
KBUILD_SRC=$PWD make cscope ARCH=arm

Linux kernel supports to build cscope files.

5. set CSCOPE_DB variable
modify ~/.bashrc:
CSCOPE_DB=/home/lanttor/Git/linux-2.6/cscope.out
export CSCOPE_DB
This step can be done manually ( I do: export CSCOPE_DB=xxx in the console for flexibility)

6. download cscope_maps.vim from

http://lab.gracecode.com/manual/cscope_vim_tutorial_zh.html

copy it to ~/.vim/plugin/ directory
