Executables and indirect shared libraries question

Question

Hello all !
On Linux when you compile a shared library you do not have to specify indirect library dependencies at link time.
But what about executables : do you have to specify all the libraries direct and indirect at link time ?
Is dlopen the only solution to by-pass such restriction ?
Thank you very much for your help !
Cheers,
Chicha

Answer 1

In the man page atexit(3) for solaris 8:
The number of functions that may be registered with atexit()
is limited only by available memory (refer to the
SCATEXIT_MAX argument of sysconf(3C)).
*** end quote ****
     You may be running out of avail mem before
the app terminates normally, objects needed by the
app never got loaded and it seq faults when it tries
to access them. Normally, according to the man page,
atexit() is called when exit() is called or main()
returns, the app is exiting. For the app to seg fault
suggests that the objects it needs aren't there,
suggesting that they didn't get loaded.
