Trouble-shooting the VM Setup for CS 2040

This note assumes you have gone through the instructions to set up your VM.

Common Problems and Solutions

• A message saying "Your host does not meet minimum requirements to run VMware Player with Hyper-V or Device/Credential Guard enabled. There are several potential fixes, and you may have to use more than one:
  • Ensure Hyper-V (the Windows hypervisor) is turned off as discussed in the message. Only one hypervisor can be running at a time.
  • Update Windows. Sometimes IT will distribute updates but not require them.
  • Disable Linux Subsystem Version 2. There are reports of having to "completely disable" this to allow VMware to work.
  • Uncheck all virtualization-related features in Windows.
  • Check for other virtual machines installed on the system. VirtualBox should be fine - many use both simultaneously - but BlueStacks and Android Studio may interfere.

• Needing to transfer data from/to the virtual host. There are many solutions; here are a few:
  • Install git and put all your project files in a course-related repository. This is a good practice anyways! Files that are on just one computer should be considered already deleted since any one computer can become inoperative at any time. Type

            sudo apt-get install -y git
    

    (into the Terminal prompt of the VM) to install it and then use git clone, git commit, and git push as usual. You will want to set up a public/private key pair and put the private key in .ssh/id_rsa on the virtual machine.
  • Open VMWare and open the resources setup for your virtual machine. Enable file copy. You may find other options there that are useful to explore.
  • Transfer the data through a cloud service such as Box or Google Drive. You can log in using the browser on the virtual machine.
• Getting an error message such as "no such directory ... /lib" when running programs or the compiler is using the wrong version. The fix:
  1. Project | Settings...
  2. On the General tab, change WorkingDirectory to $(WorkspacePath) and hit the tab key.
     • As an aside, note this is the directory that will be searched when opening files from within a program, so you will want to put any files at the top level.
  3. Click on Compiler and edit C++ Compiler Options so it reads -g;-O0;-Wall;-std=c++17 then hit the tab key.
  4. Click OK.
  Note that it's important to leave the box after changing each entry, otherwise your changes will not "stick."
