I ran into the problem Missing basic block map: 'fuzz_out//sfconvert.bblist'! At the beginning, I had the same problem as the last issue, but after I updated the path related to Dyninst, there was no error reported by UntracerDyninst any more, but the error remains. This is also the reason why I opened a new problem.
config:
I used Dynist-10.2.0 since the Dynins-9.x version was no longer supported. Other installation steps are the same as those provided in the readme. However, when I fuzzing, an error occured.

I checked the fuzz_out folder again and found that %s.dummy was successfully created, but %s.bblist and %s.cur_trace were not created correctly.

So I wonder how can I solve this problem? Do you have any suggestions? Thank you very much!

For UnTracer we don't recommend using any Dyninst version beyond 9.3.2. Alternatively, you're welcome to try out HeXcite, which uses ZAFL for its binary rewriting.

Ok, I will try to go back to dyninst-9.3.2, because the following error occurred in this version before, the related link is no longer open. Do you have any good suggestions to solve this problem?

If not, I will try HeXcite, thanks for answering!
