How to Open a SO File. SO files can technically be opened with the GNU Compiler Collection (GCC), but these types of files aren't intended to be viewed or used like you might another file type. Instead, they're just placed in an appropriate folder and used automatically by other programs via Linux's dynamic link loader ...

If the program is already running, we can also get the list of loaded shared libraries by reading the file /proc/<PID>/maps. In this file, each row describes a region of contiguous virtual memory in a process or thread. If the process has loaded a shared library, the library will show up in this file.

use the "readelf" program (e.g. toolchains/arm-linux-androideabi/prebuilt/<system>/bin/arm-linux-androideabi-readelf) to display the dynamic symbol table in your . so file, this will list the functions and variables imported and exported by your library.

The ldd command in Linux is a powerful tool that displays the shared libraries required by any given program. It's a gateway to understanding the dependencies of your Linux program and how they interact. In this example, we're using the ldd command on the 'grep' command.
