Zhengrong,
I see that nobody has answered your question and I would suggest that
the way you phrase the question is the cause. In essence, your email
reads like this:
- you changed the path and something happens, but you don't describe
what this something is
- you changed something but you don't remember what it is and you don't
feel like finding out.
There is really nothing you can expect us to do with this little
information. You need to be more cooperative if you expect us to help you.
Best
W.

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.
All the best
Z.Cheng

Then you need to adjust the path to the deal.II library at the top
of the Makefile.
Moreover, if I try to compile it in the folder of examples
itself, say,
in the step-2 directory, by typing in the terminal, for example,
" */g++
step-2.cc -o step2/*", it says:
*/fatal error: deal.II/grid/trial.h: No such file or directory
compilation terminated./*/
/
Let alone compile it in in somewhere else outside deal.II
directory in
the terminal.
This is why there is a makefile: because compiling projects with
complicated dependencies can not be done using a simple command on
the command line.

W.
