Hi all,

I am porting an application to WinCE.net, and I found that compilation
fails at the linking stage as the linker cannot find the entry point in
my compiled objects:

"LIBC.lib(wincrt0.obj) : error LNK2019: unresolved external symbol
_WinMain@16 referenced in function _WinMainCRTStartup"

Now this is strange as WinMain() is declared correctly and compiled ok,
and the linker options have /entry:WinMainCRTStartup set so things
should work ok.

I am currently linking against winmgr.lib, coredll.lib and winsock.lib
only, and NOT corelibc.lib, would that make a difference?

I tried to write a dummy test function, shown below, and tried to link
that against coredll.lib but the linker still gives the same error. So a
bit confused now and any help would be much appreciated.

Thanks

Min

file:main.c

#include <winbase.h>

int
WINAPI
WinMain(
     HINSTANCE hInstance,
     HINSTANCE hPrevInstance,
     LPWSTR lpCmdLine,
     int nShowCmd
     )
{
     int argc = __argc;
     char **argv = __argv;
     NOT_USED( hPrevInstance);
     NOT_USED( lpCmdLine);

     /* skip function name */
     argc--;
     argv++;
     return 0;
}

Linker output:

C:/WINCE420/SDK/BIN/I386/link /nologo /base:"0x00010000"
/stack:0x10000,0x1000 /entry:"WinMainCRTStartup" /incremental:no
