I have created very first C program hello world. Its exact copy of the program from 1 week, lecture continued. When I try to make hello in terminal, I got this

error message: make: *** No rule to make target `hello'.  Stop.

How to solve it please?

  • Good deal, use 'ls' to make sure that you see your hello.c file in the same directory that you're running make from.

  • I am not linux user:) tried ls, I see folders etc. But didn't find in gedit where to make a path to dropbox folder or so.

Take a look at the terminal window, are you inside Dropbox/pset1?

  • Don't worry, things like that happens from time to time even when you have a certain experience.

You should first navigate to the directory where hello.c exists then just run make hello!

  • @Arwa you should be in the same directory as the .c file before running make on it.

  • I have two programs in same folder.when I make first one, it is compiled successfully but for second one it says no rule to make target 'hello-1'.stop. If it was directory issue then it should not compile first program as well

the command/file name combination is case sensitive - make sure you have named your file "hello" rather than "Hello". If it's capitalised, try "make Hello"

  • I selected the integrated terminal but now at the beginning in the terminal I am seeing the name of the terminal. It doesn't look very aesthetic. IS there a way to fix this?

  • Thanks it seems like this helped me too. I notice i would get this problem when i would delete my termainal to start fresh. I figured it had something to do with bash

Other way which helped me is typing: cd (you will moved into default directory). Then type ls and hope you'll see your file there.

If any of these solutions above have not solved your problems, here's another solution:

the word after command "make" should be the same as the file name. example: File name:hello.c Command should be written: make hello

This was great to find, also had to adjust so that directory read: jharvard@appliance (~/Dropbox/pset1): instead of jharvard@appliance (~): by "cd" in latter

I had same issue and this was how i fixed it... I realized i wasn't running VS Code in the Harvard CS50 Codespace... So after going to code.cs50.io, on the webpage i clicked on the 'codespaces' link. So it didn't set up the CS50 environment for me... rather, on that page you should click on 'login' so that it connects you to the cs50bot invitation... then you can start all over and code hello.c, type the code and make hello...
