How is LGPL essentially the same as GPL
LGPL states that if you static-link you are essentially compiling the source into your own app, in which case binary falls under GPL status.
You can only soft-link (ie. DLL/shared object) a library with LGPL if you want to have your app non-GPL.
Or, you make a variation of the LGPL to stipulate that static linking clause does not apply in your library's case.
