CarbideC++ linker error

[Praveen_gl]

I am getting the following linker error:-
mwldsym2.exe|Linker|Error
>Undefined symbol: 'RPhone::RPhone(void) (??0RPhone@@QAE@XZ)'
mwldsym2.exe|Linker|Error
>Undefined symbol: 'RLine::RLine(void) (??0RLine@@QAE@XZ)'

I am using UIQ3SDK for building my project.
I added etel3rdparty.lib.
The other etel libraries are DLLs...

Some one... pls help with the solution

Try adding etel.lib. At least in S60 3rd edition these symbols are defined there.
