Hello everyone,

Under Solaris 10, I'm creating a library A.so that calls a function f() which is defined in library B.so. To compile the library A.so, I declare in my code f() as extern.

Unfortunately, I "forgot" to declare in A's makefile that it has to link with B. However, "make A" causes no warning, no error, and the library A.so is created.

Of course, when executing A's code, the call of f() crashes because it is undefined.

Is there a way (linker option, code trick...) to make the compilation of library A fail ? How can I be sure that all symbols refered to in library A are defined at compile time ?

Thanks for any suggestions.
