Android下使用vim

很久没有写过文章了，今天给大家分享一下如何在Android系统中使用vim。
再用Linux系统中最常用的是编辑器就是vim，奈何Android系统中很多的命令行工具都没有。所以只能通过交叉编译生成Android的一些Linux常用命令。

环境准备：

• 一个root的手机/一个模拟器
• 一个Linux主机（vmware/云服务器）

步骤

1.在Linux主机中配置ndk环境

• 下载ndk并解压 (在home目录)

wget https://dl.google.com/android/repository/android-ndk-r16-linux-x86_64.zip
unzip android-ndk-r16-linux-x86_64.zip

• 配置ndk

$NDK/build/tools/make_standalone_toolchain.py --arch arm --api 19 --install-dir ~/ndk

所有的交叉编译工具会添加的ndk目录

• 配置.bash_profile

export ANDROID_NDK=~/android-ndk-r16
export PATH=$ANDROID_NDK:$PATH

export NDK=~/ndk
export PATH=$PATH:$NDK/bin

# Tell configure what tools to use.
target_host=arm-linux-androideabi
export AR=$target_host-ar
export AS=$target_host-clang
export CC=$target_host-clang
export CXX=$target_host-clang++
export LD=$target_host-ld
export STRIP=$target_host-strip

# Tell configure what flags Android requires.
export CFLAGS="-fPIE -fPIC"
export LDFLAGS="-pie"

• source一下.bash_profile

source ~/.bash_profile

2.下载并编译ncurses-5.6

• 下载ncurses-5.6

wget https://github.com/mirror/ncurses/archive/v5.6.tar.gz
tar -zxvf  v5.6.tar.gz

• 修改include/ncurses_cfg.h

#ifndef HAVE_LOCALE_H //加了这行和endif
#define HAVE_LOCALE_H 1
#endif

• 编译ncurses-5.6

CFLAGS="-DHAVE_LOCALE_H=0" ./configure --host=arm-eabi --without-cxx-binding
make

• 继续配置.bash_profile，加上一句

export NCURSES=~/ncurses-5.6

• source一下.bash_profile

source ~/.bash_profile

3.下载并编译vim

• 下载vim-7.3并解压

wget https://github.com/vim/vim/archive/v7.3.tar.gz
tar zxvf v7.3.tar.gz

• 创建vim.patch

Patch 7.3.378
Problem:    When cross-compiling the check for uint32_t fails.
Solution:   Only give a warning message. (Maksim Melnikau)
Files:      src/configure.in, src/auto/configure

• 编译编译脚本并执行

#!/bin/bash
cp vim.patch vim-7.3
cd vim-7.3
patch -p0 < vim.patch
vim_cv_memcpy_handles_overlap=no \
vim_cv_bcopy_handles_overlap=no \

CFLAGS="-I$NCURSES/lib -pie -fPIE" \

make

4.把编译的vim放入Android的/bin目录

• 比较简单不在介绍
  需要主要的是如果是真机可能会因为只读的文件系统放不进去
  可使用下述命令重新挂载，在复制

su
mount -o rw,remount /
