Well the problem is not as well solved as I'd hoped for as cleansstate does imply a -clean and so blows away any other change I've added this to bug 2256: Unfortunately this does not only apply to menuconfig. The following scenario also does not work bitbake virtual/kernel modify a kernel source file bitbake -ccompile -f virtual/kernel bitbake virtual/kernel The latter does not run do_install This is on ppc I tried the cleansstate solution, as suggested by Darren in comment 7 but unfortunately cleansstate implies clean so it removes the whole tree (including the modified file). Best regards, Frans (ps: for me it is nice to have do_install being run as I combine device tree and kernel image into a single file using mkimage in do_install_append.; will try next time to do a -c compile -f followed by a -c install f) _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
