Important upcoming change: starting Gecko 12, pre-Windows 7 SDKs will no longer be supported

tl;dr: if you’re on an outdated Windows build configuration, upgrade.

I just checked in a patch to mozilla-inbound to drop support for SDKs prior to the Windows 7 SDK. Depending on when you last updated your build configuration, your Mozilla build might break.

Everything’s documented on the Windows SDK versions page on MDN; here’s a quick summary of what you need to do:
  • If you’re on Windows 2000: Upgrade to Windows XP, Vista or 7.
  • If you’re on Windows XP SP1 or below: Update to the newest service pack.
  • If you have an older SDK (Vista or 2003): Install the Windows 7 SDK instead. You can either download it separately or use Visual C++ 10 Pro, which comes with it.
  • If you use Visual C++ 8 (2005) Express or Visual C++ 7.1 (VS2003): Upgrade to Visual C++ 10 (2010; recommended; pro or express) or Visual C++ 9 with Service Pack 1 (2008; pro or express).
