For PE executable, I can list the imported symbols using
dumpbin /imports FILE.EXE
or using the depends utility which is GUI application.
`nm ELF-binary' just returns "no symbols".
The output from objdump is a little excessive for this purpose, and requires a good bit of parsing to find the actual imports.
I prefer readelf for this purpose:
As you can see, the required libraries are marked with "NEEDED".
