Subject: [PATCH v3 11/16] kernel.bbclass: Copy include/config/auto.conf in STAGING_KERNEL_BUILDDIR
Date: Tue, 20 Jan 2026 09:52:41 -0800 [thread overview]
Message-ID: <20260120175246.2052341-12-Harish.Sadineni@windriver.com> (raw)
In-Reply-To: <20260120175246.2052341-1-Harish.Sadineni@windriver.com>
From: Yoann Congal <yoann.congal@smile.fr>
Linux commit aaed5c7739be ("kbuild: slim down package for building
external modules")[0] states that include/config/auto.conf is also a
file needed for out-of-tree build.
This avoids this error when building an out-of-tree Rust kernel module:
| make -C .../tmp/work-shared/qemux86-64/kernel-source M=$PWD
| make[1]: Entering directory '.../tmp/work-shared/qemux86-64/kernel-source'
| make[2]: Entering directory '.../tmp/work/qemux86_64-poky-linux/rust-out-of-tree-module/git/sources/rust-out-of-tree-module-git'
| .../tmp/work-shared/qemux86-64/kernel-source/Makefile:779: .../tmp/work-shared/qemux86-64/kernel-build-artifacts/include/config/auto.conf: No such file or directory
