Naively right clicking my binary and selecting "profile as->function
graph" results in an error box saying:
"Attempting relaunch"
"Some functions defined in the selected files could not be found in the
binary. Attempting to relaunch with those files removed. Alternatively,
try profiling again with all files selected"
Obviously I am missing a (the?) point somewhere, but I have no clue as
where to look. Is there more to profiling than just installing the
plugin and systemtap? Any doc pointers or howtos are appreciated.
Aside from installing the plugin and having systemtap, the kernel debuginfo is necessary, but only for the 0.4 release. The nightly releases and future ones will likely not depend on the kernel debuginfo (It is possible to achieve the same functionality without it).
You could take a look at the actual error by going to Errors -> Open Log, located at the top right of the Call Graph View. Although it seems like the issue is that the kernel debuginfo is missing.
