Error C1047: Object file created with an older compiler than other objects

Question

I have a project that I\'m building in C++ in Release mode in Visual Studio 2008 SP1 on Windows 7 and when I build it I keep getting:

fatal error C104

Answer 1

I would suggest reinstalling VS 2008 SP1. Have you installed a different VS (e.g. VS Express) in the meantime? This is known to cause interference with an existing VS installation.

You could try checking the compiler and linker versions by running cl.exe and link.exe from the Visual Studio command prompt.
