Sure, you're welcome. Thumb should not fundamentally be a problem provided the platform and tools support it, and it sounds like in your case it does.
Your assumptions about what you need are correct, I believe (i.e., you don't need the gui). You may want to inspect the code, however, because there are routines for installing and loading the TAP driver that may be of interest. They are in taputil.h,.c cellcore.dll is used to provide the Windows Connection Manager stuff, and in openvpn.exe this in openvpn.c, around line 203, and around line 284. I should have conditional-compiled that as an option, but I didn't. Similarly the support routines are in wince_portstuff.c at line 1631 through the end, and they can go, too (actually if you remove those first and compile, the compile should fail and you can find if there was anything I missed, but that should be it). Generic CE platforms don't use the Windows Connection Manager and do networking in the more conventional way, so you can probable do without it, and remove the cellcore.lib from your link step. Assuming your error message really means 'missing dlls' instead of 'invalid binary' then you should be better off. Again, if you want to send me your compiled binary, I can inspect it more closely if that is useful. -Dave -----Original Message----- From: jonathan openvpn [mailto:jonathan.open...@gmail.com] Sent: Thursday, May 28, 2009 1:56 AM To: dave Cc: openvpn-devel@lists.sourceforge.net Subject: Re: [Openvpn-devel] CE port needed DLLs 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. 2009/5/27 dave <d...@ziggurat29.com> That message usually means the binary is hosed, and I believe missing dlls give a different message. Are you sure Thumb is correct for your platform? Are you using a consumer device like a pocket pc phone, etc, or is it a custom board? I ask that because the existing code does use some functionality peculiar to the pocket pc (phone) that is not generally available on other platforms, yet the SDKs ofen include the headers and import libs, allowing you to successfully compile, but then you can't run it on the target device. When you say 'client application' are you meaning just the gui, or the whole entire set of programs (i.e., the TAP driver, the openvpn executable, and the gui). You can use DUMPBIN to find the dlls from the exe, and also inspect the header to see the cpu configuration. Here is a short list, if it helps: openvpn: * coredll.dll * w2s.dll * iphlpapi.dll * wininet.dll * ole32.dll * cellcore.dll tap-ce: * ndis.dll * coredll.dll ovpncmgr: * iphlpapi.dll * toolhelp.dll * cellcore.dll * ole32.dll * mfcce300.dll * coredll.dll * winsock.dll Your build may (will) differ depending on your platform, because your platform builder may have put some of these features in different dlls. That list was for PocketPC. Now, the cellcore.dll, you may not have on other platforms. It is needed for supporting Windows Connectin Manager, and you can surgically cut out that functionality if your platform doesn't have it. Most of the rest is fairly standard. Before doing surgery, you may wish to re-check your assumptions. Also, if you wish to zip up your problem binaries and send them to me directly, I will do a quick inspection for you. -dave -----Original Message----- From: jonathan openvpn [mailto:jonathan.open...@gmail.com] Sent: Wednesday, May 27, 2009 5:36 AM To: openvpn-devel@lists.sourceforge.net Subject: [Openvpn-devel] CE port needed DLLs Hello. I'm triying to execute a Windows CE 5.0 porting of openvpn client application. I've been successful on compiling it but when i try to execute i receive the message: "openvpn is not a valid WindowsCE application". I am compiling to ARM-Thumb architecture. I suspect there is a problem with needed DLLs. Could anyone tell me wich DLLs are needed and where could i get them? Thank you very much.
