I have an executable (C++) which is the exclusive user of the some shared library that it uses only during the initialization phase.
I would like to free memory used by this shared library, because I am running on embedded system.
How can I achieve this?
I know that dlopen() will load shared library, and hope that following dlclose() will free this lib memory.
1. Still I do not know what method should be used to make dynamic linker look again into executable and resolve symbols of the newly appeared symbols ?
2. And how to tell the dynamic linker ld-linux.so to postpone the symbol resolution until dlopen() will load the library?
3. Whether to compile and link executable with this library or leave unresolved symbols?
Waiting for your advises,
