It appears as if upgrading to the kernel-ml on centos 7 breaks the
bcc-tools that are available in Centos 7. Installing kernel-ml-devel
does not resolve the epbf compile errors.
Does anyone have a quick solution for this? It looks like I need to
replace kernel-headers with kernel-ml-headers, but that leads to rpm
dependency hell, as doing so causes dependency check failures for
glibc iirc.
Thanks,
Dave.
