But yes, it is that easy. Well, if you want to use -lfoo instead of
dlopen(), you need libfoo.so too, not just foo.h. But the gist of it is that
with dynamic linking, the copyleft limitations of the GPL are trivial to
This is in fact, a good thing, because that shows that copyright is weak.
Remember that the GPL is not a good thing, it is an evil thing: using the
weapons of your enemies against them. If the weapons are weaker than
expected, so much the better.
