Re: "Linker Error - LNK2019"

Porting is going to mean "rewriting". Most of the APIs for low-level
network stuff, other than WinSock, don't exist on Windows CE. As for this
other DLL, you'll have to port that, too. Desktop DLLs will not work on
Windows CE devices.

As for WinSock, you don't need to add *any* paths to anything. You need to
add the *library* to the list of input libraries. Presumably your device
SDK *has* WinSock and, when eVC is pointing to the right device type, it
knows where to find the libraries. Select Project | Settings | Link and
simply add "winsock.lib", or "ws2.lib" if you're using WinSock2, to the list
of libraries, a name you find in the Windows CE help for the WinSock
functions. You should be clear that you cannot, under any circumstances use
libraries from the desktop for your Windows CE device.

Hi Paul,

I am developing an app for a gateway that interacts with the live phy
devices on the network. The same app was developed in VS6 and its
practically
working on my PC. But now to port it to target with wince5 image i am
porting
my app to EVS4 i have done all the linking in EVS4 same as in VS6. The
ones(calls) you were telling that you never heard of are actually another
app
dll that i am using which i am linking properly by prviding the correct
path
in project->settings->link->input->additional lib path(i wonder at least
that
should be working properly), also i have checked again that the path to
WinSock lib is also correct under tools->option->directory->library files
tab. But still the problem remains.
Could the problem be something else maybe some backward compatibility
issue
of VS6 and EVS4.

Many of those calls don't exist in Windows CE (the time ones and some of
the
NT-specific ones). Others are implemented in the WinSock library which
you
are clearly not linking with. Still others I've never heard of, so
you'll
have to figure out why your code can't resolve them (are they in a
library
that you used to link with?) Link with the right libraries for the API
functions that you are calling and take a look at the freeware time
library
from OpenNETCF, www.opennetcf.org, for a possible way to get the time
calls.
For the things that just don't exist for Windows CE, you'll have to write
your own versions of them in terms of calls that *do* exist on Windows CE
or
change the source code for your program to do things a different way or
get
rid of the features that require those things.

My guess is that, based on what you're trying to call there, you are
attempting to do something that makes no sense at all for Windows CE.
Maybe
you should tell us what you're trying to do and we can give you a read on
how practical that is.

I developed an app in VS6.0 and OS using WinCE5.0 and build the SDK for
the
same. Now I am trying to port my App to EmbeddedVS4.0 which is
compatible
with Wince5.0 SDK and platform builder. But I am getting a lot of
linking
errors " Error - LNK2019 unresolved external symbol". Though i am able
to
trace the same symbol to a header file which i have included.
Can some body resolve this issue?
thanks in advance.

Here is the snapshot of errors i am getting.
