Vim + gtags + gtags-cscope + Universal-ctags

改用gtags + gtags-cscope + Universal-ctags

Universal-ctags

$ git clone https://github.com/universal-ctags/ctags.git
$ cd ctags
$ ./autogen.sh
$ ./configure --prefix=/usr
$ make
$ sudo make install

gtags + gtags-cscope (global)

DL: Here (目前版本6.6.8, 往下找) 


$ ./configure --with-universal-ctags=/usr/bin/ctags --prefix=/usr
$ make
$ sudo make install

$ cp /usr/local/share/gtags/gtags.conf ~/.gtags.conf (給vim用)

靠這些插件來使用

gutentags_plus


ref:
Vim 8 中 C/C++ 符号索引：GTags 篇

• E609: Cscope error:
  似乎是整個的路徑如果有空白，比方說 "/home/user/Foo\ Bar/"，這樣的話所產生的 cscope.out 就不能讀

• tags靠這些插件的設定，放在 ~/.cache/tags 要定期整理一下，會滿肥的
