PPS sieve errors
(Message 140042)
Posted 308 days ago by  Nicholas Peter Bamber
I cannot see anything that looks like a program I should run.
This one:
-rwxr-xr-x 1 boinc boinc 972208 May 12 2019 tpsieve_0.3.10d_linux64
run as:
./tpsieve_0.3.10d_linux64 -h
It should print help.
I managed to get an strace output:

I don't know but maybe this line is significant:
stat("init_data.xml", 0x7ffd814456b0) = -1 ENOENT (No such file or directory)
I checked on another machine. That has a valid init_data.xml. So I do believe that is the issue. How do I fix this and should the code be improved?
