Hi! My name is Konstantin. I'm experienced C/C++/Delphi developer. After analysis of provided source codes I made following conclusions: it written in C++ using C++ Builder 6 and seems you've never had full source files set, because number of critical hand-made packages and libraries are missing, eg. dtEngine wrapper, pdfLib wrapper, ImageLib wrapper, etc. And all those packages/libraries should be developed before we will be able to just compile the code. The second source set is much worse and badly incomplete. The conclusion is: it's much easy to build software you need from scratch then put a lot of efforts to restore the missing parts without any support documentation.
