linking

Hi,

I would like to trace calls to some 3rd party library which are made from another 3rd party library.

Example: I want to trace calls to library A. My application statically links library B, which in turn is statically linked to library A.

In case of dynamic linking I could write library A2 with wrappers for functions which I want to trace of library A and use LD_PRELOAD=A2.so. Then, my wrappers will be called instead, and I will see the trace. In my case I cannot use dynamic linking.

Is it possible to achieve the same using static linking?

Thanks,
Robusta
