I have some Cinema 4D Plugins for Clients that need to be compiled at least for Release 14. The only problem is: The R14 SDK won’t compile with the newer versions of XCode. On Clang 5.1, it results in 2 errors about friend-declarations. You need Clang 5.0 to successfully compile the R14 SDK and plugins.
With OS X Mavericks, I just installed the XCode Command Line Tools from Late October, 2013 from the Apple Developer Downloads page. But with Yosemite, you can no longer install this package!
