VIM 配置及内核代码编译

1. 编译安装python

  1.1 下载 python 源代码

$wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
$tar -zxvf Python-3.6.5.tgz; cd Python-3.6.5/

  1.2 安装 zlib 相关依赖

$sudo yum -y install zlib*

  1.3 配置生成 makefile

$./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" --enable-unicode=ucs4 --enable-optimizations

  1.4 编译安装 python

$make
$sudo make altinstall 
$sudo ln -sv /usr/local/bin/python3.6 /usr/local/bin/python
$sudo unlink /usr/bin/python; sudo ln -sv /usr/local/bin/python /usr/bin/python
$sudo unlink /home/tops/bin/python; sudo ln -sv /usr/local/bin/python /home/tops/bin/python

  升级 python 之后可能会因为语法不一致导致依赖于旧版本 python 的软件工作不正常
  例如运行 yum 可能会出现如下错误

$ yum 
File "/usr/bin/yum", line 30 except KeyboardInterrupt, e: SyntaxError: invalid syntax

  解决的办法：
  1. 升级 yum 
  2. 或者修改 yum 使用的语法解释器
      修改 #!/usr/bin/python 为 #!/usr/bin/python2.7
  3. 在编译VIM之后把 /home/tops/bin/python 软连接回 python2.7

#Sctipt to switch to python 3 $cat ~/rain/p3.sh

sudo unlink /home/tops/bin/python
sudo ln -sv /usr/local/bin/python /home/tops/bin/python
ls -al /home/tops/bin/python

sudo unlink /usr/bin/python?
sudo ln -sv /usr/local/bin/python /usr/bin/python?
ls -al /usr/bin/python ################################# #Sctipt to switch to python 2 $cat ~/rain/p2.sh

sudo mv /home/tops/bin/python /home/tops/bin/python-bak
sudo ln -sv /home/tops/bin/python2 /home/tops/bin/python
ls -al /home/tops/bin/python

sudo mv /usr/bin/python /usr/bin/python-bak?
sudo ln -sv /usr/bin/python2 /usr/bin/python?
ls -al /usr/bin/python

2. 编译安装VIM

  2.1 安装相关依赖，如果可以直接安装 python可以省去前面编译过程

$sudo yum install lua lua-devel –y
$sudo yum install ncurses-devel
$sudo yum install -y ruby ruby-devel lua lua-devel luajit uajit-devel ctags git python python-devel python3 python3-devel tcl-devel perl perl-devel perl-ExtUtils-ParseXS perl-ExtUtils-XSpp perl-ExtUtils-CBuilder perl-ExtUtils-Embed

  2.2 删除存在的 VIM

sudo yum remove vim vim-runtime gvim

  2.3 克隆 VIM 源代码

$git clone https://github.com/vim/vim.git; cd vim

  2.4 配置生成 makefile

$./configure --enable-multibyte --enable-perlinterp=yes --enable-rubyinterp=yes --enable-python3interp=yes --enable-luainterp=yes --enable-gui=auto --enable-cscope --disable-selinux --with-features=huge --prefix=/usr/local

  如果编译之后的 VIM 版本信息里面不包含 +python3，可以尝试添加 Python3 配置路径
