Missing headers in SDK example

[VampirLestat]

I have some problems to build the "imageconv" example from S60_2nd_FP2 SDK:

WARNING: Can't find following headers in System Include Path
<EIKCFDLG.H> <EIKCHLST.H>
(Sys Inc Paths "\Symbian\8.0a\S60_2nd_FP2\EPOC32\INCLUDE\" "\Symbian\8.0a\S60_2nd_FP2\EPOC32\INCLUDE\TECHVIEW\")
Dependency list for "\SYMBIAN\8.0A\S60_2ND_FP2\EXAMPLES\MULTIMEDIA\IMAGECONV\SRC\CIMAGEAPPUI.CPP" may be incomplete

So far I know, this are Eikon or, up from Symbian 5.1, Uikon headers, right?

I thought inherent, the Series 60 UI (Avkon) is only an additional layer to modify the behavior/appearance of the underlying Uikon UI... And I thought also, I could use both frameworks to develop Series 60 applications. Uikon if I wanted portability, and Avkon for some special Series 60 features...

But it seems, I have no chance to use Uikon at all, because of missing headers and (much worse) probably missing functionality on the target devices...

Am I right with my guesswork, or what I am doing wrong?
