linker/loader and shared libraries (C, C++).

Question:

I want to have a compiled main routine written in C++ be able to
dynamically load an arbitrary "C" function at runtime.

I could use the linkage editor to create a single executable, but I
want to have the main routine be the executable that I load from the
command-line and then let it take care of loading the appropriate
subroutine(s) dynamically.

Is this possible ?

Response:

You can use shared libraries - but you think there may be a problem
with getting the main program to find the correct paths to the
subroutines.

Response:

Told Customer that he should "ld" to construct a loadable object.  E.g.

ld -o obj.o -H512 -T512 -e entry_point file1.o file2.o ... -lc ...

would build an object that can be loaded via the load() function.

We also discussed correct declarations of the C functions (in C++)
that will be loaded.
