This is because the DLL uses an different tree of object classes. It 
includes System, Classes etc. units, as duplicates of the main program 
units (see the linker map).

In theory you need another DLL/so which contains all these common units 
(RTL+basic  LCL), and which is used by all modules of the project. In 
practice this may not work, though :-(
