I am trying to compile the Win32 Example of the Parrot ARDrone SDK v1.8 using Visual Studio 2012 Express for Windows Desktop. I am running Windows 7 64-bit. The SDK is written in C, not C++.
I've managed to get through every error so far, but this one has me stumped.
When Run, I get these 3 messages in the Error List:
Warning 1 warning LNK4001: no object files specified; libraries used C:UsersNetexDesktopARDrone_SDK_Version_1_8_20110726ARDrone_SDK_Version_1_8_20110726ExamplesWin32VCProjectsARDroneWin32ClientLINK Win32Client

I've tried many suggested solutions, including setting the SubSystem in Linker->System to "Not Set" and setting the entry point manually, which gets rid of the 2 errors and replaces it with:
`Error 2 error LNK1221: a subsystem can't be inferred and must be defined'
I've tried setting the Platform Toolset to v90 (which it was originally compiled in, I believe), which gets rid of the warning, but the errors persist.
QUESTION: What is causing these messages, and how can I fix it? Is it because I am trying to compile a Win32 console program on a 64-bit system?
Any help is much appreciated,
