Yeah, I thought about that a lot, but I couldn't come up with a constructive suggestion. The best I could come up with to have kbuild generate a shell script helper or use a shell script helper to actually build each .o file. However, the speed hit probably makes that unacceptable, although it would make it easier, I suspect, to use that abstractionas part of making something which ccache or distcc could use to cache (or distribute to a cluster) all of the steps needed to build each object file. Maybe a helper C program instead? - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
