This will take some thought, but looks easy enough to do.
Somehow with all the AutoFu layered in, POPT is already testing
checking for dlfcn.h... yes
which includes a run-time ELF symbol lookup
/* Find the run-time address in the shared object HANDLE refers to
of the symbol called NAME. */
extern void *dlsym (void *__restrict __handle,
__const char *__restrict __name) __THROW __nonnull ((2));
which means -- if __handle on the current application can be achieved --
that POPT could do the symbol lookup at run-time, not through traditional
That would add the ability to, say, do arithmetic on
any ELF symbol in an application using a RPN calculator.
Whether POPT 2.0 _SHOULD__ permit this type of functionality
is a very different question.
