Almost certainly, yes. Though maybe not all off them but enough that<br>
say "nm exe/cactus_sim_ET_2021_05_BC" reports something for<br>
cactus_source (eg in my case nm exe/cactus_sim | grep<br>
'cactus_source$' -> 0000000006fdc1c0 D cactus_source). Gdb needs to be<br>
able to resolve the "cactus_source" symbol into the actual address.<br>
Otherwise it will be hard to find out that correct starting point for<br>
the linked list of tar file fragments.<br>
<br>
If you can still run the the executable then running it with a minimal<br>
thornlist that says <br>
<br>
ActiveThorns = "Formaline"<br>
<br>
will write out the source code tarball.<br>
<br>
Yours,<br>
