Hi, I have a centos 7.8 workstation that I'm trying to install lttng-modules & lttng-tools from source. Based on your install instructions I'm working on installing the modules part first and its failing. I am getting the error: Make entering directory /usr/src/kernels/3.10.0-1127.19.1.el7.x86_64 Arch/x86/Makefile:166 *** CONFIG_RETPOLINE=y, but not supported by the compiler. Compiler update recommended... stop Make: modules error 2 Help, how can I get this program to install? Im stuck. Also, my work environment is classified so there is no access to internet from high side. ---------------------------- John Weber Ball Aerospace ITS ND System Administrator 10 Longs Peak Dr., Broomfield, CO 80021 C: 303-807-3608 P: 303-234-2103 E: jweber1@ball.com [cid:image001.jpg@01D6BF29.AD6C5250] [cid:image002.jpg@01D6BF29.AD6C5250] This message and any enclosures are intended only for the addressee.
