fgrep and egrep are deprecated
Since I last updated my Linux distribution, I keep having these warnings each time I compile RustBelt or other Iris related projects:
fgrep: warning: fgrep is obsolescent; using grep -F
egrep: warning: egrep is obsolescent; using grep -E
fgrep: warning: fgrep is obsolescent; using grep -F
egrep: warning: egrep is obsolescent; using grep -E
There are a lot of them, and they flood my terminal.
They should be replaced by grep -F
and grep -E
in the various Makefiles or the Iris project repositories. I guess this is quite easy to do if you have the right script to update all the repos (I assume @jung has such a thing, otherwise tell me), but I don't have such a thing.
