I have successfully installed VMware Player and the cs50 appliance 19 on my desktop computer. I'm running a 64-bit operating system.

But I am unable to power on the appliance. I installed VMware Player on another laptop that I have and imported the appliance, but I can't create folders like Dropbox and pset1 using the make command.

When I try to create them using the make command, I get an error message saying

No rule to make target

How can I get one of these working?

  • Installing/removing Microsoft Office applications has nothing to do with VMware Player and the appliance. What's the error message that you're getting when trying to power on the appliance?

  • To configure Dropbox and create directories, please refer to pset1 specification page or to this link!

First of all check if the VM Ware Player is 64-bit compatible. The make command is for compiling C programs. You have to use mkdir for creating directories.

Secondly you don't create the Dropbox folder, it automatically gets created for you. Just click on the CS50 "Start" button, click on Dropbox, and follow the instructions.

To make the Pset1 folder inside the Dropbox folder simply type cd Dropbox and then mkdir pset1 in the terminal.

  • Thanks. That is what I did after some trial and error. uma1966original comments by the user 2279543
