Traces the shared-object dependencies of a binary, and graphs them.
./sotrace.py /path/to/foo out.dot
dot -Tsvg -o out.svg out.dot
eog out.svg
It is also possible to map the actually loaded .so files of a process by giving the tool a PID instead of a file.
./sotrace.py PID out.dot
Dynamically linked binaries pull in a large amount of dependencies. It is often hard to get a good idea of what gets pulled in, recursively.
This tool will create a graphic that clearly shows the dependencies.
It is also a useful tool to identify software bloat.
Currently, it will only find dependencies that are dynamically linked.
This means it will miss:
- statically linked dependencies.
To see the dynamically loaded libraries, that were opened with dlopen() you need to run the tool on a PID, not a binary.
To run this tool, you need python3.
To create the graph, you need dot from the graphviz package.
Personally I use eog to view the svg, but any browser would work, or also Imagemagick's display command.
