Got a user who claims he was running this program, then it broke recently. Almost no updates in a while, and none relevant. I'm guessing the program's compiled from fortran to c.... Anyway, the issue's on two servers. On one, I installed a couple of compat libs, and it runs. The other still fails (but it doesn't have some of the i686 libs. When it fails, it's immediate, and reports dying with a SIGKILL. ldd claims it's not a dynamic executable, but file tells me it's a 32 bit ELF.... Running it under strace gives me no more. So, as one last resort (Confess! You have three last resorts!), I'm trying to run it under gdb. On the system it runs on, I can b main, and it gets there when I tell it run. On the other... the address appears to be the same, it's in his NFS-mounted home directory - it never gets to main, it just reports the sigkill.
So, what I'd *really* like to do is not tell it run, but next, or step, but I can't.
Anyone heavy enough into gdb to be able to suggest where I can tell it to break during the program initialization phase, before it gets to main?
Possibly something still not right in the execution environment. Try "export LD_DEBUG=all" then run the program. ("unset LD_DEBUG" to reverse.) Did you edit ld.so.conf and run ldconfig on the second machine? Also check "sudo ausearch --success no --interpret -ts today"
