I use ggtags in order to improve my efficiency. I follow the manual to setup emacs environment. https://tuhdo.github.io/c-ide.html
However, during editing the cpp files in the projects. Chance are high that the emacs will not respond. And the background will do something like "Parsing numeric_op.hpp (LL)...done". This will spend more than half an hour to do this. I don't know how to deal with this thing. Does anyone have the same situation? Thank you very much.
