elf_diff is unconsolable :-( Something went wrong Error: Unnable to find objdump command Don't let this take you down! Have a nice hot coffee and start over.

elf_diff relies on GNU binutils to extract symbol informations from binaries. Binutils - if installed - comes with a set of executables like objdump and readelf.

To solve your problem you need to either install the binutils package that is compatible with the compiler that you used to build the binary or, if already installed, add the directory that contains binuntils binary to your Path/PATH variable.

elf_diff also has a command line argument that allows specifying a binutils path if modifying the Path variable is not feasible.
