OK, maybe I've confused "fair use" with just plain "use".
whichever.  The point is that I can't figure out how
you can use a source code library without compiling it and
LINKING it with outside code.

otherwise you have a bunch of bits in RAM that you 
can never execute, therefore never use.  so, to me,
it seems that either linking is plain "use", or its
under a righted granted to the copyright holder,
(such as a derived work), but "fair use" allows the 
user to do the link anyway.

and the LGPL is going out of its way to 
assert that linking is "deriving"
when I can't see it as anything but use.

I said nothing of distribution in any of this discussion.

if I have a JPEG that you've copyrighted and given to me, 
you're saying I can't convert it to a viewable format 
that my computer video board can understand?
because its a derived work and you didn't give me those rights?

then I have a file that I can't use.

some derivation must be allowed to do the conversions from
a compressed, binary file, to a 2D array of RGB values
for my PC. "use" or "fair use", but its got to be in there
somewhere. otherwise, you're saying that if I pay your for
a JPEG, and you only grant me rights to "use" but not 
'derive', then I can't view it on my computer.

uh, miscommunication overload.
I did not mean to imply public display.

I was continuing the JPEG analogy where
someone wants to use my JPEG file,
create a RGB version, and display it
on their PC.  i.e. privately.
