I use xcodebuild for Release builds of my non-Mac-App-Store product. Suddenly it is failing to compile two source files, and scrolling up in the output I see this is apparently caused by “Failed to load dependencies output contents”. Here is one of them:

Indeed that BkmxBasis.d file is not there. Its parent directory includes intermediate build files for about 10 source code files in the project. For 8 of the source code files, there is a trio of files, “.d”, “.dia” and “.o”. But for the two source code files that failed, there is only the “.dia”; indeed the “.d” is missing and of course the “.o” is missing. (The project has over 500 source files. The 10 source files referred to in here all begin with “B”. I guess that maybe it skipped “A” for some reason, then quit trying after these two failed.)

The project still builds fine in Xcode, either Debug or Archive.

This message is just a warning (which it says in the message, albeit buried in the first line). It usually happens because that command or possibly some other command failed (causing Xcode to halt that command), and Xcode then tries to read dependency info from that command (or from other commands which have been cancelled). So, it’s a bug in Xcode. But it is harmless other than adding this extra verbiage to the build log.

In other words, this is not the cause of the build failure you’re seeing. It’s probably emitted somewhere else in that log, not reproduced in the log snippet above (but likely immediately nearby).
