Is it good to link a shared library against other shared libraries?

I have an application X which uses shared libraries A,B and C. Shared library C also uses some symbols from Shared library A. Application X is linked against A and B during compile time and it does dlopen开发者_StackOverflow to load C at run time.

My question is:

Is it a good idea to link C against A during link time or leave the symbol resolution for runtime?

Your option 1. But it does not work that way.

1. You link C with A.
   As A is a dynamic lib this will do nothing phsically.
   It verifies that all dependencies will be satisfied by A at runtime.

2. At runtime when you dlopen() the shared lib C
   It will open C and if you had not already linked against A it would also open A
   But since A is already open it will just resolve symbols in C with the A that is open.

I would go with the option 2. Leave the resolution for runtime. Late binding is the best option. Also I never knew that option 1 was possible :)
