Link errors

[georgica1979]

i wrote a code like BossPuzzle example , ofcourse modified!
whwn i compile .cpp no errors!
When i Build look:
Doing first-stage link by name
link.exe @C:\DOCUME~1\Jock\LOCALS~1\Temp\nma02736.

What is wrong!
i included all! is something else?

You should edit your .mmp file and state all libraries that you are using.
This "unresolved external symbol" means that the linker can't link your code to the right library DLLs because you haven't specified which libraries to use.

[georgica1979]

Look at my mmp file:
TARGET Sambata2.app
TARGETTYPE app
UID 0x100039ce 95
TARGETPATH \system\apps\Sambata2
SOURCEPATH ..\gui
SOURCE Sambata2.cpp
RESOURCE Sambata2.rss
USERINCLUDE ..\inc
SYSTEMINCLUDE \epoc32\include
LIBRARY Sambata2eng.lib
LIBRARY euser.lib apparc.lib cone.lib eikcore.lib CKNDLG.LIB gdi.lib ws32.lib estor.lib efsrv.lib
and i have the same errors!
What is the problem???

[georgica1979]

i have the same errors!

[nanard]

For each unresolved symbol look for the Class in the Series 60 SDK Reference.
example for error LNK2001: unresolved external symbol "public: int __thiscall RFs:elete(class TDesC16 const &)" (?Delete@RFs@@QAEHABVTDesC16@@@Z)

Location: f32file.h
Link against: efsrv.lib

so you should have
LIBRARY efsrv.lib
in .mmp

Check also that you included a SOURCE line for every .cpp of your project
