I am working on a mini framework that acts as an abstraction over the

Most or all of the Lazarus source is covered under the GPL. It is my
understanding that the GPL requires derivative works (by static
linking) to also be open source. Do derivative works necessarily need
to be under the same license? I would like to release my framework
under a more permissive license to encourage commercial extension
authors from the Delphi side to port to Lazarus.
Actually, the IdeIntf is LGPL + linking permission.
So, if you only use the IDEIntf (and LCL, RTL)
and do not ship a pre-build IDE with your package included
then you can use any license.
Users can build an IDE with your package, but must publish the build exe
(if I am right: the GPL used for the IDE, does not restrict what you do
on your PC, only what you can publish)
The idea always was:
- IDE => GPL, so it stays free, including any forked IDE must be free
for ever.
- IDEIntf => LGPL, so commercial (or other) plug-ins are possible
