I get the warning when compiling a static library. MACOSX_DEPLOYMENT_TARGET is actually set to 10.3.

It doesn't look like XCode sets the environment variable for a "MasterObjectLink" phase.

If I set the environment variable and run the it from the command line, it works fine.

I've reported it as an XCode bug.

Anyone seen this before or know a workaround?

Well, whatever you think MACOSX_DEPLOYMENT_TARGET is set to, the linker is being told it's 10.1 (which is the default when it's not set at all.)

Being able to see the linker invocation, not just the errors produced, would help clear this up.

Check your Target's Build Settings for the configuration you're building and make sure the Development Target is set to 10.3. (One of the most common errors in Xcode is setting a build setting on the wrong configuration or on the project instead of the target).
