ldd-report

A utility for generating dependency reports of ELF libraries and binaries.

Overview

ldd-report is a command-line tool that analyzes ELF files in a directory and reports their dynamic library dependencies. It provides functionality similar to the ldd command but with more structured output and additional features.

Features

Recursively scan directories for ELF libraries and binaries
Identify dynamic library dependencies for each ELF file
Map dependencies to their actual paths on the system
Show missing dependencies that could cause runtime issues

Installation

From Source

git clone https://github.com/username/ldd-report.git
cd ldd-report
cargo build --release

The compiled binary will be available at target/release/ldd-report.

Usage

ldd-report [OPTIONS] --dir <DIR>

Options

  -d, --dir <DIR>      Libraries path (directory to scan for ELF files)
  -s, --silent         Return exit code only (no output)
  -h, --help           Print help
  -V, --version        Print version

Example

# Analyze all libraries in a directory
ldd-report --dir /path/to/libraries

# Analyze but only return exit code
ldd-report --dir /path/to/libraries --silent

Output Format

For each ELF file found, the tool outputs:

The full path of the file
A list of required libraries and their resolved system paths
Missing dependencies are marked as "NOT FOUND"

Example output:

/path/to/libraries/libexample.so
  libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6
  libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6
  libcustom.so => NOT FOUND

Requirements

Linux operating system
ldconfig available in the system path
Rust 1.56 or later (for building from source)

Dependencies

clap: Command-line argument parsing
goblin: ELF file parsing
