And thus it and the related kernel options cannot be enabled. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/gcc-plugins/Kconfig https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/gcc-plugin.sh With my effort and the patches attached, I still cannot make it pass. The following misplacing of the file cannot be properly fixed by simply moving the missing file. /build/tmp-glibc/work/intel_x86_64-wrs-linux/linux-yocto-dev/5.3-rc++gitAUTOINC+5e432442d5_31a7feab3b-r0/recipe-sysroot-native/usr/bin/x86_64-wrs-linux/../../lib/x86_64-wrs-linux/gcc/x86_64-wrs-linux/9.1.0/plugin/include/tm.h:39:36: fatal error: ./config/i386/linux64.h: No such file or directory 84656 1 4553 zhe.he 2019-08-13 10:11:48 +0000 Created attachment 4553 kernel-source.patch 84657 2 zhe.he 2019-08-13 10:14:01 +0000 The attached kernel-source.patch or similar one needs to be applied to enable the error print. 84658 3 zhe.he 2019-08-13 10:15:43 +0000 The attached oe-core is simply for testing "bitbake virtual/kernel -cmenuconfig". Further change is still needed for do_configure. 84670 4 randy.macleod 2019-08-15 14:40:46 +0000 Khem and Zhe please work on this. It's not clear if it's a toolchain issue or not. 93591 5 randy.macleod 2022-06-23 15:17:46 +0000 Richard is going to check on this. I"ve CCed Sundeep since I think he worked on a bug for WR that is related. 93595 6 sundeep.kokkonda 2022-06-23 15:29:34 +0000 The same error was reported in WR Linux when below flags are enabled. CONFIG_GCC_PLUGIN_LATENT_ENTROPY=y CONFIG_GCC_PLUGIN_STRUCTLEAK=y CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL=y The build issue was resolved with the patch from below link. https://www.mail-archive.com/openembedded-core@lists.openembedded.org/msg157205.html Hope this helps... 96963 7 randy.macleod 2023-10-24 14:24:52 +0000 Bulk move from 4.99 or 0.00 to 5.99 104115 8 randy.macleod 2026-01-29 16:29:28 +0000 Sundeep - for post-6.0.
