The recipe has this line: do_populate_lic[depends] += "virtual/kernel:do_patch" When devtool is used it looks like the do_patch task is removed. When reset the do_patch task is listed again (tested using bitbake -c listtasks). When the line above is removed the recipe compiles fine. perf is included in the image using IMAGE_FEATURES += "tools-debug tools-profile" The error is: ERROR: Task do_unpack in ../meta/recipes-kernel/perf/perf.bb depends upon non-existent task do_patch in my-linux_0.0.0.bb ERROR: Command execution failed: 1 The kernel recipe inherits kernel.bbclass. 71190 1 jon.richardson 2017-03-10 02:22:17 +0000 Correction, the error is: ERROR: Task do_populate_lic in /home/jonathar/work/yocto/sxc_test/poky/build/../meta/recipes-kernel/perf/perf.bb depends upon non-existent task do_patch in /home/jonathar/work/yocto/sxc_test/poky/build/../meta-brcm/common/recipes-kernel/linux/brcm-linux_0.0.0.bb Then there is a subsequent error if I remove do_populate_lic[depends] += "virtual/kernel:do_patch" from perf.bb. ERROR: Task do_unpack in ../meta/recipes-kernel/perf/perf.bb depends upon non-existent task do_patch in my-linux_0.0.0.bb ERROR: Command execution failed: 1 This line from kernelsrc.bbclass: do_unpack[depends] += "virtual/kernel:do_patch" seems to cause the second error. Even though do_unpack is set to no_exec it's not enough to prevent the dependency error. Removing the line allows further progress but seems to cause other problems. I don't have a proper solution yet. 71532 2 jon.richardson 2017-03-21 18:11:13 +0000 Here is a fix or partial fix. There are a few issues. 1. STAGING_KERNEL_DIR isn't set when devtool is run on the kernel. This is probably a devtool bug. We set it manually to our source location. 2. In perf.bb I removed the following line. I don't think it's required anymore because commit 6e36cc9c40b16a51a60a3cbbd051da9285f37bcf removed LIC_FILES_CHKSUM: -do_populate_lic[depends] += "virtual/kernel:do_patch" 3. In kernelsrc.bbclass I removed this line: -do_unpack[depends] += "virtual/kernel:do_patch" Not sure why perf's do_unpack dependency is required - there is no source for perf, it's compiling the kernel's code tools/perf. If kernelsrc.bbclass is intended to compile kernel utils only then I don't think it's required. As mentioned before, do_patch task doesn't exist when you devtool the kernel. Thanks. 73365 3 sgw 2017-05-18 19:04:35 +0000 *** Bug 11520 has been marked as a duplicate of this bug. *** 73565 4 sgw 2017-05-30 15:13:12 +0000 http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=ab0747e7c6d93e0143cf059241ad914cf055f362
