A simple, cross-platform program to display dynamic libraries used by an executable

Overview

I found it a pain when writing cross platform programs to figure out which dynamic libraries I was linking with. On macOS, there is otool and objdump, on linux, ldd, and on Windows, dumpbin.exe. Once I discovered the awesome goblin crate, I was surprised no one had created a simple program to just dump the dynamic libraries used by an executable, so I created one.

NOTE: There aren't many surprises here, but if you aren't aware, ldd looks up transitive dependencies, but this utility does not. This means this utility lists only the direct dependencies of an executable, which is consistent with the other utilities listed above, and makes this program consistent across executable types and platforms.

Install

cargo install --locked dynlibs

Features

Simple to use
Platform independent (tested on Windows, Linux, macOS)
Can be used as a library crate as well, if needed

Examples

Linux:

$ dynlibs /bin/ls
Binary type: ELF

Dynamic libraries:
    libselinux.so.1
    libc.so.6

Windows:

PS dynlibs c:\windows\hh.exe
Binary type: PE

Dynamic libraries:
    ADVAPI32.dll
    KERNEL32.dll
    msvcrt.dll

Mac:

% dynlibs /bin/ls
Binary type: Mach-O (Fat)

Dynamic libraries:
    Index 0:
        /usr/lib/libutil.dylib
        /usr/lib/libncurses.5.4.dylib
        /usr/lib/libSystem.B.dylib
    Index 1:
        /usr/lib/libutil.dylib
        /usr/lib/libncurses.5.4.dylib
        /usr/lib/libSystem.B.dylib

Status

This is a very simple program, and besides some possible slight enhancements, it is more or less complete.
