Hi,
Somebody also reported the same issue while building glibc.. https://www.linuxquestions.org/questions/showthread.php?p=5872643#post5872643 [http://images.linuxquestions.org/lqthumb.png]<https://www.linuxquestions.org/questions/showthread.php?p=5872643#post5872643> bug while building glibc-2.27 with new gcc-8.1.1 and perl-5.28.0<https://www.linuxquestions.org/questions/showthread.php?p=5872643#post5872643> www.linuxquestions.org If you try to rebuild glibc-2.27 as for SFS or in Slackware-current you get that message, not a good one: -------------------------------- touch /tmp/g The problem also occurs with the old GCC, so i doubt that is the issue.
