Ok, so still same situation however it appears that the make program is able to use the devtoolset gcc but I still get the error. My work environment is classified however, this system has already been updated. If I try to up or down with versioning I am sure to have a dependency nightmare. I'm not sure what to do at this point. I guess I'm kind of confused over this whole issue of installing your software. I'm running centos 7.8 which is recent. Why isn’t my current version of gcc good enough? Is lttng 2.12 so new it only works on linux newer than 7.8??? sorry just not sure why this problem even exists at this point. Does 2.12 only work on linux version 8+? Would an older version of lttng be even work it? I mean the software that I install for our environment is as new as possible. I support a team of aerospace software developers. Maybe this just isn’t an option and maybe we should look at something else. I also have version 2.4 but that seems to be to old in comparison to the other software we use. Thoughts?

Running this will get you verbose output while building which should help you determine which compiler and other tools are used :

   make CC="/opt/rh/devtoolset-6/root/bin/gcc" V=1
