I use a custom distcc build to build the kernel, and I don't waste time setting up that environment for a testbox, which means I can't build a module for the test kernels because it would be using a different compiler in that case. > Anyway, this gives us a good question, "should test binaries be made by > server or client(testbox) environment?"

Is that what this would need? I would think we could add a CONFIG_KSELFTEST_MODULES, that would build any modules needed for selftests and have them in /lib/modules just like any other module. -- Steve > > Shuah, what would you think about this? > > > make[4]: *** [ipmodify.ko] Error 2 > > make[3]: *** [sub-make] Error 2 > > make[2]: *** [__sub-make] Error 2 > > make[2]: Leaving directory `/home/rostedt/work/git/nobackup/bxtest/trace' > > make[1]: *** [ipmodify.ko] Error 2 > > make[1]: Leaving directory `/work/git/linux-trace.git/tools/testing/selftests/ftrace/ipmodify' > > make: *** [all] Error 2 > > > > > > Thanks (on my way to bed), > > Thank you :), > > -- 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/
