Why do I get an Abort message when running the Quartus® II software on RedHat Linux? - Why do I get an Abort message when running the Quartus® II software on RedHat Linux? Description You may get an Abort message when starting the Quartus II software version 3.0 if the /etc/nsswitch.conf file does not list the "files" entry first in the "hosts" lookup order. To solve this problem, modify the hosts line of your /etc/nsswitch.conf file so files is listed first. For example, if the "hosts" line of your /etc/nsswitch.conf file is hosts: dns nis files , you should change it to hosts: files nis dns . This problem will be fixed in a future version of the Quartus II software.
