ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

Here are two use cases:
you want your binary file to be smaller in size.
you want to hide symbols from a proprietary program to make reverse engineering more difficult.
What makes me confused is that, in the man page, it is mentioned that strip -s will remove all symbols. I do not know what are the symbols in the context, but if they are exported symbols (functions/variables), and when they are removed, how could other module use the exported functions/variables?
He means that strip removes a human readable symbol table - like the one you see with
A long time ago, stripped executables loaded and ran faster than the same file that was not stripped. Today, you might strip files to make them smaller for a distribution package.
If I make a debug mode build of application, then if I remove such symbol table, could the debugger work properly? Because I think without a human readable information symbol table, how could the person who makes the debug assignment know the meaning of each internal symbol?
