lddtopo-rs

Uses lddtree-rs to build the dependency graph of a provided library and run topological sort to get the order in which they should be loaded.

Usage:

RUST_LOG=info cargo run -- --shared-library-path /lib/x86_64-linux-gnu/libtiff.so --output-file /tmp/result.json

Then check the file /tmp/result.json and /tmp/result.dot

➜  lddtopo-rs git:(main) ✗ jq -r '.topo_sorted_libs' /tmp/result.json
