Only Exuberant-ctags is the correct name for apt to install the ctags version.

See where the version number is 5.9~svn20110310-11, has not been updated for 7 years. Such a bag, moldy for 7 years, throw it:

sudo apt remove exuberant-ctags -y

Installation of fresh Universal-ctags

What is Universal-ctags? A maintained ctags implementation, Https://ctags.io, a responsible ctags implementation, open source on GitHub and continuously updated and maintained.

Don't say more, install it quickly:

cd /tmpgit clone https://github.com/universal-ctags/ctags./autogen.sh./configure --prefix=/opt/software/universal-ctags  # 我的安装路径。你按自己的情况调整。make -j8sudo make install

Update the Ctags executable file to the system path? No, I choose how to create a link:

# 如果你装了emacs-snapshot，那么现在的ctags命令实际上链接到了/usr/bin/ctags-snapshot，要先删除链接文件：# sudo rm /usr/bin/ctags# 然后，把新编译安装的universal-ctags链接过来：sudo ln -s /opt/software/universal-ctags/bin/ctags /usr/bin/ctags

Configuring Ctags in Vim

The key sentence is: set tags=./.tags;,.tags , put in the Vim configuration file.

Can be configured directly with my VIM:

cd /tmpgit  clone --depth=1  https://github.com/amix/vimrc.git  ~/.vim_runtimesh  ~/.vim_runtime/install_awesome_vimrc.shgit  clone  https://github.com/zchrissirhcz/dotfilescp  dotfiles/my_configs.vim  ~/.vim_runtime/

Using Ctags

cd ~/work/opencv   # 随便进入到一个你的c++工程目录ctags -R .  #递归地生成.tags文件

Then use shift+] and shift+t in vim to jump into and out of the function definition.

enjoy!
