Since commitf1d87664b8("kbuild: cross-compile linux-headers package when possible"), 'make bindeb-pkg' may attempt to cross-compile the linux-headers package, but it fails under certain circumstances. For example, when CONFIG_MODULE_SIG_FORMAT is enabled on Debian, the following command fails: $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg [ snip ] Rebuilding host programs with aarch64-linux-gnu-gcc...

This commit adds a new profile, pkg.linux-upstream.nokernelheaders, to guard the linux-headers package. There are two options to fix the above issue. Option 1: Set the pkg.linux-upstream.nokernelheaders build profile $ DEB_BUILD_PROFILES=pkg.linux-upstream.nokernelheaders \ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg This skips the building of the linux-headers package. Option 2: Install the necessary build dependencies If you want to cross-compile the linux-headers package, you need to install additional packages. For example, on Debian, the packages necessary for cross-compiling it to arm64 can be installed with the following commands: # dpkg --add-architecture arm64 # apt update # apt install gcc-aarch64-linux-gnu libssl-dev:arm64 Fixes:f1d87664b8("kbuild: cross-compile linux-headers package when possible") Reported-by: Ron Economos <re@w6rz.net> Closes: https://lore.kernel.org/all/b3d4f49e-7ddb-29ba-0967-689232329b53@w6rz.net/ Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: Ron Economos <re@w6rz.net> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu>
