Hey W, Thank you for your reply. I changed the path to the library, but it still could not work.
Actually, it worked a few days earlier by simply typing in the terminal "g++ step-2.cc", but later I want to set the path by using emacs, say, f"emacs .bash_profile", which failed, and some other actions which I could not remember. Now if I type $PATH, it turns out to be: bash: /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/zhengrongcheng/deal.II/lib: *No such file or directory* See the highlighted one? I don't know how to fix it. Maybe this is the problem. Please let me know if you can help with it. Thanks.
