I've seen this type of message myself from applications compiled with
cegcc too, when there's something wrong with the *.def file from which
we create the lib*.a file that ends up linking our application to a DLL.
If the DEF file defines an API that isn't in the DLL on your WinCE
device, then any application that accesses this API will provide this
message at startup. My best guess is that the Windows CE runtime loader
(which "connects" the DLLs) detects this situation and issues this
error.
Two pieces of advice :
1. You may be interested in trying to run the application from gdb.
(arm-wince-cegcc-gdb for instance). It'll give the message in another
form.
2. Our arm-wince-cegcc-objdump may provide additional info also. Use it
on the executable and check out which API's the application calls from
which DLL.
By the way, which application are you talking about ?
