Split the engine in several static libraries

Hi everyone! I managed to split every engine component (e.g., core, sfx, gfx) in static libraries, and then link them in the executable. I wanted this because I want to keep the engine separated from the various executables that will use them. The thing is that it compiles well, but it won't work, the log just says the following:

main.cs (15): Unable to instantiate non-conobject class GuiCanvas.

The static libs are using the exact same project properties than the TGEA executable, preprocessor definitions, etc. (The only difference, of course, is Configuration Type)
Also the linker gave several LNK4221 warnings in a couple of "empty" cpp files. (The files are the same ones used in the original TGEA project which is working).
Does anybody know if there's a way to do this?
I'm using TGEA 1.8.0 and VC++ 2008. Thanks!
