Hi Ian, Arnaldo

With this change, does it implies that the traceevent in "tools/lib/traceevent" is not
going to be used hereafter ?

I am seeing this compile error in a system with libtracevent installed:

util/evsel.c: In function 'evsel__rawptr':
util/evsel.c:2787:36: error: 'TEP_FIELD_IS_RELATIVE' undeclared (first use in this function); did you mean 'TEP_FIELD_IS_FLAG'?
2787 | if (field->flags & TEP_FIELD_IS_RELATIVE)
| ^~~~~~~~~~~~~~~~~~~~~
| TEP_FIELD_IS_FLAG
util/evsel.c:2787:36: note: each undeclared identifier is reported only once for each function it appears in


The system has libtraceevent and its devel installed.
But TEP_FIELD_IS_RELATIVE is not defined in header file of the system installed version.
Whereas it is there in header file in tools/lib/traceevent


# grep TEP_FIELD_IS_RELATIVE /usr/include/traceevent/event-parse.h
# grep TEP_FIELD_IS_RELATIVE ../lib/traceevent/event-parse.h
TEP_FIELD_IS_RELATIVE = 256,

# rpm -qa|grep libtraceevent
libtraceevent-1.1.1-8.el9.ppc64le
libtraceevent-devel-1.1.1-8.el9.ppc64le

How we can handle this ?


Thanks
Athira
