Re: [Openvpn-devel] CE port needed DLLs

[jonathan o. <jon...@gm...>]

Hello.

First of all, thank you for the quick response.

We have other applications running on the Windows CE distribution and the
linker option "MACHINE" is set to "THUMB".
We are using a custom developed board, and we develop our applications
through Visual Studio 2005.

We only need to stablish a connection to a VPN server without need of a GUI,
all configuration must be transparent to the user. Therefore I think we only
need the openvpn executable and TAP_CE driver. If i'm not wrong, the
ovpncmgr module is to provide a GUI for the openVPN client. Is that correct?

When no dll is provided, and I try to debug the application from Visual
Studio connected to the device, i get the message: "An error occurred that
usually indicates a corrupt installation (code 0x8007007e). If the problem
persists, repair your Visual Studio installation via 'Add or Remove
Programs' in control Panel"
Some webs refer to that error like some archives are missing. When I put the
dlls you have listed below, the error changes to: "openvpn is not a valid
WindowsCE application". I suspect that some of the dll may not be correct
for my platform. Could it be the source of my problem?

I have not been able to find the cellcore.dll for our platform. Does it mean
we cannot use the connection manager functionality? I have read in some
forums that this functionality is not present on Windows CE...

Sorry for my ignorance, I am pretty new on Windows CE.

Your help is so much appreciated. Thank you very much.

Jonathan.
