Hi, Karl. We've had a lot of recent work go into Dyninst regarding statically-linked binaries, but I've not seen this particular error yet. I have a few questions to narrow down the situation:
1. Which version of Dyninst are you using? 2. Which compiler and version was used to build the mutatee? 3. What OS are you using? 4. Which version of libc are you using? If you could provide this information on our Github issue ( https://github.com/dyninst/dyninst/issues/568), I would greatly appreciate it as it helps us better keep track of user-provided feedback. Many thanks. - Tim On Mon, Mar 18, 2019 at 5:27 PM Karl Ott <[email protected]> wrote: > Howdy, > I am trying to instrument a statically linked binary and no matter > what I have tried the mutator code can't seem to find the functions in > my static instrumentation library.
