gcc 4.9.1 in OS X Yosemite - gcc: warning: couldn’t understand kern.osversion ‘14.0.0'

Question

I install OS X Yosemite and now i have a huge problem with gcc 4.9.1 compiler. I hope some one can help me please.

I try to compile my program and i have the warning

Answer 1

It seems to want a current version of XCode command line tools. When I first typed "make" after installing Yosemite I got a warning and a dialog box saying that I did not have XCode command line tools and asked if I wanted to install them. I did so, and everything worked.

However one user did not get this dialog and instead got the error message as shown. The "xcode-select --install" did not work, so it seems like it may have kept the outdated command line tools and header files.

The MACOSX_DEPLOYMENT_TARGET=10.9 solution did work for him. However the compiles seemed to be a lot slower.
