I am trying to start doing the Pintos Stanford project on Ubuntu. I downloaded the tar file that the Stanford website provides but when I try and run 

pintos -- run alarm-multiple

I get the following error:

Unrecognized character \x16; marked by <-- HERE after   if ($<-- HERE near column 7 at /home/adambomb/src/pintos/src/utils/pintos line 911

I found on another stackoverflow post that I should pull from latest version of pintos:

git clone git://pintos-os.org/pintos-anon pintos

But doing this gets me an error:

Cloning into 'pintos'...
fatal: read error: Connection reset by peer

I'm not really sure where to go from here and could use some insight to fix either of these problems. I don't really know where to go from here.

I ran into the same issues as you trying various guides on the internet (eg. this guide) and looking through StackOverflow. However, this youtube video helped me the most.

Steps below can be found here. I'm using Ubuntu 18.04.

  1. Run sudo apt-get install qemu
  2. Get latest pintos source code from pintos public git repository or download older version with this link
    2a. Under heads, find master and click the tree hyperlink
    2b. Click snapshot and download the .tar.gz file to your directory
  3. Run tar -xvzf pintos-anon-master-{value}.tar.gz where {value} is the commit-id
  4. Open /utils/pintos-gdb with vim and edit GDBMACROS variable to point to the full path for pintos directory
  5. Open Makefile with vim and edit LOADLIBES variable name to LDLIBS
  6. Compile utils directory by navigating to /src/utils and running make
  7. Edit /src/threads/Make.vars (line 7): change bochs to qemu
  8. Compile threads directory by navigating to /src/threads and running make
  9. Edit /utils/pintos (line 103): replace bochs with qemu
  10. Edit /utils/pintos (~line 257): replace kernel.bin with the full path to kernel.bin
  11. Edit /utils/pintos (~line 621): replace qemu with qemu-system-x86_64
  12. Edit /utils/Pintos.pm (line 362): replace loader.bin with the full path to loader.bin
  13. Open ~/.bashrc and add export PATH=/home/.../pintos/src/utils:$PATH to the last line.
  14. Reload terminal by running source ~/.bashrc
  15. Run pintos with pintos run alarm-multiple
