When I try to compile breakout I get the following error:

breakout.c:16:10: fatal error: 'spl/gevents.h' file not found
#include <spl/gevents.h>

Did I miss an update?

  • Which version of the appliance do you have installed? If you started the class last year and are using an older version, spl is missing.

Be sure you are using the 2014 version of the CS50 Appliance. It has the SPL libraries built in.

  • Thanks, that's it. The update does not work for me, unfortunately, and I cannot install another VMware workstation either. Jul 31, 2015 at 16:49
