Hi,

If you look carefully at the compiler commands there that fail they include flags for generating dependency files (-M…), they are not actually compiling the code yet. I don’t have the rules in front of me right now but our build rules evidently don’t want to fail a build if the compiler isn’t able to generate some of the .d files, for various reasons. Those .d files are actually Makefiles and get included so are created in the first pass of the build. GNU-make finds that it has rules to rebuild makefiles so it runs them before attempting to run the actual compile, and that’s where the build actually fails. This is fairly complex, but there is documentation about what GNU make does which is worth reading if you really want to understand it.

HTH,

- Andrew
