I am looking for ways I can reduce the size of a shared library. The problem is that my library uses external libraries created by other people, and I only use some of the functions from those libraries. My questions is this: is there a way I can strip out specific symbols from those libraries, i.e. the ones I don't need? This is one of the ways that I thought might lower the size of my library.

What other techniques can I use to decrease the size? In terms of my own code, I am exposing the functions that need to be exposed. However, I still want my libraries' size to be much smaller so I am looking for other ways to do so.

Unfortunately, you would need the source code of 3rd party libraries to be able to achieve your objective. There are several ways in which a binary generated by the compiler could be made to a lower size. one such way is to use the compiler switch -o when you are using gcc. https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html

Another important thing to note is that when you have a reduced binary size it might impact your runtime in some instances.
