Make plugins fails

Question

make plugins fails with lots of undefined unix functions in makeswf.cpp
I added #include <unistd.h> to makeswf.cpp to get past this problem.

Nathan,
point of a plugin is to specify a "generic" operation to a specific use case. So in your example, you have the problem that the abstraction layer cannot provide a generic function which is specified by the plugin.
Of course, by some obscure and over-engineered approach, you might be able to solve a setup as you like. Still, i recommend you to provide only a single layered abstraction in the context of design. Of course, implementation can "stack" this. So in your second example, "Fruit" would provide generic operations on ALL kind of fruits without any implementation. Depending on the specific fruit, you would either leave the operation as dummy (no override) or add an override which indicates something like "This operation doesn't make sense with this type of FRUIT". For other fruit, you would add an override like "YAMYAM, tasty!"....

PS: Please note that i haven't discussed any "architectural design for deployment" here. So the question starts for "one lvlibp" or "several"? But as you already quoted Michael Lacasse's Community Entry, you know where to find useful information
