I'm ambiguious on the meaning here.
If libblah.a is GPL, and evilcorp does a
gcc -o marketable_binary_a propiatery_license.c -lblah
gcc -o marketable_binary_b propiatery_license.c -Bstatic -lblah
does that imply that marketable_binary_a is then considered a derived
work and must be GPL'd ?
As far as I understood it up until Liam's post, only if I for example
changed libblah.a and recompiled it and/or statically linked (not sure
about statically linking) then the 'modified' GPL'd code would have to
Further, my understanding was that if I took libblah and added lots of
bits of C code to it and gave it to <another> that at that point the
entire lot of libblah+super_modification would be as a derived work, GPL'd.
Personally, I *think* it's ... well slimy, to make a function call to
GPL code, to rely on a GPL bit of code and not .. well, give back, in
the same ilk, but again.. I guess I'm just looking for clarification.
Is marketable_binary_a under an obligation to be GPL?
Is marketable_binary_b under an obligation to be GPL?
I don't think that either *are* at all, only libblah+super_modification
is, but... I could be wrong.
