Then you can argue that we should break it up in a build and run rule. However, my understanding how people just build and run the the tests for that particular subsystem that they develop for, like: make -C tools/testing/selftests/<subsystem>/ Cheers, Anders -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

So why does a similar dependency work for samples in the main Makefile (even listed twice!)? Documentation/ samples/: headers_install samples: headers_install Or perhaps this also doesn't work? > Then you can argue that we should break it up in a build and run rule. > However, my understanding how people just build and run the the tests > for that particular subsystem that they develop for, like: > make -C tools/testing/selftests/<subsystem>/ I'm still a bit puzzled: how can you "build and run" the tests when cross-compiling, as you don't run the tests where you build them? Thanks! Gr{oetje,eeting}s, Geert
