global gtags

安装

需要安装global

生成gtags文件

切换到环境变量设置的各个目录里，执行gtags命令即可，会有4个G开头的文件生成。

➜  sources pwd/usr/share/sources➜  sources ls glibc-2.27           glibc-libidn-2.10.1.tar.gz     glibc-ports-2.16.0         GRTAGS  linuxthreads     SDL2-2.0.8.zipglibc-2.27.tar.gz    glibc-linuxthreads-2.3.tar.gz  glibc-ports-2.16.0.tar.gz  GSYMS   linuxthreads_dbglibc-libidn-2.10.1  glibc-localedata-2.0.6.tar.gz  GPATH                      GTAGS   SDL2-2.0.8

在shell上使用

配置环境变量

export GTAGSLIBPATH=/usr/include:/usr/share/sources:$GTAGSLIBPATH:.

Spacemacs 配置

在.spacemacs文件(dotfile)里

dotspacemacs-configuration-layers

(gtags :variables gtags-enable-by-default t)

dotspacemacs/user-config

(setenv "GTAGSLIBPATH" (concat "/usr/include"                                         ":"                                         "/usr/share/sources"))
