Hi Ryan, the source doesn't compile on RHEL. RHEL9 currently only
has json-c-devel-0.14 which doesn't provide json_object_new_array_ext().
It only las json_object_new_array() This seems to be the only
compilation problem on RHEL9.
However, systemtap is also supposed to work with RHEL8, where I
seem to see more compile time issues. Please, check. I'm happy
to provide a test box for you if interested.
Thanks,
Martin
