<div dir="ltr">Hi Duo,<div><br></div><div>It looks like you're missing a library for the Z3 SAT solver used by the taint plugin. I suspect the missing package is libz3-dev - can you try installing that from apt if you don't have it already?</div><div><br></div><div>If you're using Ubuntu, did you set up PANDA with our install_ubuntu.sh script? If so, that should have automatically set up all the dependencies for you (by installing the packages listed in the panda/dependencies/[os name:version]_*.txt files). If you used the install script and still ran into this issue we might have a bug in that script that we should fix.</div><div><br></div><div>Cheers,</div><div>Andrew</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jul 15, 2021 at 4:06 PM Duo Zhang <<a href="mailto:duozhang@iastate.edu">duozhang@iastate.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hello developers, <br></div><div><br></div><div>I tried the latest version of PANDA with the file_taint plugin but it failed with the image you provided online.
