Hi all, I am trying to implement some C++ functionality in C. Suppose I have several libraries that share behavior and properties, such as version, working directory, and so on. I want other libraries to extend this behavior without having to duplicate any code. For instance: typedef struct base { char version[32]; char path[32]; } base_t; typedef struct foo { base_t *base; int data; } foo_t; typedef struct bar { base_t *base; int data; } bar_t; lib-base.so: base_get_version(base_t *, char *); base_get_path(base_t *, char *); lib-derived-foo.so: foo_one_method(foo_t *, int data); foo_two_method(foo_t *, int data); lib-derived-bar.so: bar_one_method(bar_t *, int data); bar_two_method(bar_t *, int data); I want the derived modules to link with the base library, so that my application can link with only the derived modules and still be able to call the base functions without having to link to that library or call 'wrapper' functions in the derived modules. Is there a way to do this? jm --
