vim for Android编译

环境准备

1. 下载ndk并解压：

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

2. 准备独立工具链：

   cd android-ndk-r16
   export NDK=`pwd`
   export NDK19=~/ndk19
   $NDK/build/tools/make_standalone_toolchain.py --arch arm --api 19 --install-dir ~/ndk19
   

   • 这里创建了名为~/ndk19的目录，其中包含了android-19/arch-arm系统根目录，以及32位arm环境的二进制工具链。
3. 准备编译环境变量：

   # Add the standalone toolchain to the search path.
   export PATH=$PATH:$NDK19/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"
   

4. 最终则可以使用make defconfig && make或./configure && make来进行最终的编译。

ncurses-5.6

1. 下载ncurses-5.6并解压：

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

2. 进入ncurses-5.6目录并编译：

   cd ncurses-5.6
   ./configure --host=arm-eabi --without-cxx-binding
   make

Trouble Shooting

1. make过程中出现如下错误信息：

   error: undefined reference to 'localeconv'
   

2. 解决方案：
   1. 修改文件include/ncurses_cfg.h，将：

      #define HAVE_LOCALE_H 1
      

      修改为：

      #define HAVE_LOCALE_H 0
      

vim-7.3

• 开始使用vim-7.4编译，发现依赖boost，但android环境无boost，则换用vim-7.3。

1. 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
   

2. 进入vim-7.4目录并编译：

   cd vim-7.4
   
   export NCURSES=/home/ubuntu/repo/ncurses-5.6
   
   vim_cv_memcpy_handles_overlap=no \
   vim_cv_bcopy_handles_overlap=no \
   vim_cv_memmove_handles_overlap=no \
   vim_cv_stat_ignores_slash=no \
   vim_cv_getcwd_broken=no \
   vim_cv_tty_group=world \
   vim_cv_terminfo=yes \
   LDFLAGS="-L$NCURSES/lib" \
   CFLAGS="-I$NCURSES/lib" \
   vim_cv_toupper_broken=no \
   ./configure --host=arm-eabi --with-tlib=ncurses
   
   make

Trouble Shooting

1. 执行configure时出现如下错误：

   error: could not compile program using uint32_t.
   

2. 则需要打上如下patch文件：

   Patch 7.3.378
   Problem:    When cross-compiling the check for uint32_t fails.
   Solution:   Only give a warning message. (Maksim Melnikau)

安装

将src/vim和runtime打包，推送到Android系统的/data/vim目录，其中需要给/data/vim/vim加上可执行权限，再在/vendor/bin目录下添加如下内容到文件vim，并赋予可执行权限即可：

export TERM=xterm
export VIMRUNTIME=/data/vim/runtime
/data/vim/vim $1

运行时出现如下错误：

E437: terminal capability "cm" required

这是因为是环境变量TERM没有设置或者配置错误导致，只需要执行如下命令即可：

export TERM=xterm
