[slurm-dev] Re: using gdb to debug slurm-15.08?

Thank you for that very helpful info, Michael. I see what you mean about the extra flags. I haven't been compiling using "--with debug". Something strange happened this last time I compiled though: gdb just started working. I'm thinking it may have been a networking issue with my cluster, because t

Christopher, thank you for pointing out how to tell if the file is stripped. slurmd is not being stripped apparently: [mkg52@head ~]$ file `which slurmd` /usr/sbin/slurmd: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped

[slurm-dev] Re: using gdb to debug slurm-15.08?

You may still get a message about "debuginfo" RPMs because the SLURM spec file disables the building of them, but the RPM configuration and GDB configuration on RHEL are done in such a way as to assume that they exist. What really matters is whether or not your binaries and libs have, or don't ha

[slurm-dev] Re: using gdb to debug slurm-15.08?

Thanks for the help everybody. So far I've tried looking for more debugging options in the spec file, doing Bjorn's suggestion, and just using --with debug like Michael suggested. They all leave me with the same issue though. When I try to use gdb by attaching to the slurmd process, it still gives

[slurm-dev] Re: using gdb to debug slurm-15.08?

That should already be the case. At least in 15.08.x, the spec file contains: %define __os_install_post /usr/lib/rpm/brp-compress %define debug_package %{nil} The first line has the effect of disabling the stripping of binaries (among other things). The second line prevents the -debuginfo pack

[slurm-dev] Re: using gdb to debug slurm-15.08?

[Apologies to the list if someone has already responded to Michael, but I don't recall seeing it.] Hi Michael, By far the easiest way to debug Slurm problems is by doing your own, local build, outside the context of RPM. You can find appropriate ./configure arguments (at least to start)
