I have a core dump file that has been generated by an erlang application and would like to analyze. This is my first time using gdb. I installed gdb but no luck running it with the executable and the core dump file.
I give gdb the executable and the core dump as
gdb erts-5.9.3/bin/beam.smp core
When I run that, I get,

"/Users/sad/projects/core" is not a core dump: File format not recognized
How can I solve this?

"/Users/sad/projects/core" is not a core dump: File format not recognized
$ file core
/Users/sad/projects/core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), ...
Mac OS does not use ELF
file format. We can safely assume that this core
came from some other system, not the one you are trying to analyse it on.
It is still possible to analyse that core
on the Mac OS system, but you need:
In general, it is much easier to do the post-mortem analysis on the host where the crash happened.
