I've tried the 0.71 release from the OpenFrameworks website and also cloning the repo and using the develop branch.
Attempting to compile the ProjectGenerator using the repo yields different results depending on the solution configuration.

Unfortunately I'm a complete fool at C++, and I wanted to use OpenFrameworks to get into it. I haven't been able to get it to compile on OS X 10.8 or Windows 7 (using VS 2012 RC and the openframeworks.cc version) or Windows 8 (with VS 2012 RTM).
I can't imagine this still being an issue, since the project generator has changed so much since 0071, so I'm closing this. If this still occurs with current master branch, feel free to re-open it.
