How Can I List Exported Symbols from a Shared Library (.so File)?

Listing Symbols in a Shared Library (.so File)

To list the symbols exported from a shared library, a number of tools can be used.

nm

The nm utility lists symbols from object files and libraries. To list the symbols in a .so file using nm, use the following command:

nm -gD yourLib.so

objdump

If your .so file is in ELF format, you can use objdump to list its symbols. The -TC option can be used to display symbols and their types:

objdump -TC libz.so

readelf

Another option for listing ELF symbols is readelf. The -Ws option provides information about the symbol table:

readelf -Ws libz.so

Additional Options

• -C: Demangles C symbols, making them more readable.
• -g: Includes local as well as exported symbols.
• -D: Lists only defined symbols.
