--- Comment #2 from William Bader <williambader at hotmail dot com> --- Thanks for the quick reply. The system is a VM. I have the results of 'free' below. The VMs where the build worked all have slightly more memory and swap. What is the recommended minimum to build gcc-6? $ free -h total used free shared buff/cache available Mem: 993M 239M 382M 10M 371M 564M Swap: 1.0G 977M 47M Regards, William
