I've seen this only when the executable contains an invalid reference.
This means that the cegcc image for the DLL (libcoredll.a) contains more
functions than the actual DLL on your device, and the application
actually uses one of these.
I've recently created tools/dll/testapi.c (in the cegcc svn) which you
can use to verify whether your DLLs do contain the APIs required by your
application. E.g. :
pavilion: {33} rsh ipaq /temp/testapi.exe coredll open
coredll doesn't know about open
pavilion: {34} rsh ipaq /temp/testapi.exe coredll MessageBoxW
coredll implements MessageBoxW (0x03F7F720)
If you run objdump -x on your executable, then you'll see output such
as :
DLL Name: AYGSHELL
vma: Hint/Ord Member-Name Bound-To
80000054 84 <none>
16250 51 SHInitExtraControls
16266 63 SHSipPreference
00016014 00016060 00000000 00000000 00016608 00016160
DLL Name: COMMCTRL
vma: Hint/Ord Member-Name Bound-To
16278 10 CommandBar_AddAdornments
16294 12 CommandBar_Create
162a8 15 CommandBar_GetMenu
162be 19 CommandBar_InsertMenubar
162da 65 InitCommonControls
Each of those functions could be the problem.
Which version of WinCE does your device use ?
