vim - is there a way to see output of previous ":! g++ %" without rerunning? -

-

when coding, check code running :! g++ %. map command <f5>. takes while compile , want see errors without spending time recompiling. also, want compare new output previous one.

is there way see previous output of :! ...?

provided have g++ configured makeprg, can use :copen reopen last list of errors :make command. 

set makeprg=g++\ %

then, compile, use 

:make

when compile completes, errors listed in quickfix window, can (assuming errorformat correctly configured) used jump lines on errors occur. works out of box c/c++.

if dismiss quickfix window, retrieve last error list 

:copen

review :help quickfix , :help makeprg full gory details on how works.
