according to forum, building kernel in default path (/usr/src) is not secure, so I using KERNEL_DIR to indicate a different location, it's works so far but not anymore now. seems like $SYSSRC didnt get the correct value. here is my env setting: KERNEL_DIR=/path/to/kernel_build here is the build log: * Package: x11-drivers/nvidia-drivers-460.67 * Repository: gentoo * Maintainer: sudinave@gmail.com soap@gentoo.org * USE: X abi_x86_32 abi_x86_64 amd64 driver elibc_glibc kernel_linux tools userland_GNU * FEATURES: network-sandbox preserve-libs sandbox userpriv usersandbox * Package: x11-drivers/nvidia-drivers-460.67 * Repository: gentoo * Maintainer: sudinave@gmail.com soap@gentoo.org * USE: X abi_x86_32 abi_x86_64 amd64 driver elibc_glibc kernel_linux tools userland_GNU * FEATURES: network-sandbox preserve-libs sandbox userpriv usersandbox * Determining the location of the kernel source code * Found kernel source directory: * /usr/src/linux-5.10.25-gentoo * Found kernel object directory: * /path/to/kernel_build * Found sources for kernel version: * 5.10.25-gentoo * Checking for suitable kernel configuration options...

maybe this is the reason why failed? https://github.com/gentoo-mirror/gentoo/commit/34d1a7f4c31488f25cbf673893c8eefadc26a95a#diff-15506a01894cd930827e2378d2f518dfcd980553edff5de9e906bb83d7b9e9f8R144-R148 if use driver; then BUILD_TARGETS=module linux-mod_src_compile \ KERNELRELEASE="${KV_FULL}" \ src="${KERNEL_DIR}" fi https://github.com/gentoo-mirror/gentoo/commit/1c9748e1bfa1bbe3c3147630d351a01bb267e318#diff-a50220f6edf5025ebe3ff775b1f232f6c977da32e3e65291aaa59c75ab25fd1cR160 use driver && linux-mod_src_compile
Odd, I just re-tested it using KERNEL_DIR=/tmp/linux emerge -1 nvidia-drivers with nothing in /usr/src and it built fine. make -j11 HOSTCC=x86_64-pc-linux-gnu-gcc CROSS_COMPILE=x86_64-pc-linux-gnu- 'LDFLAGS=-m elf_x86_64' NV_VERBOSE=1 IGNORE_CC_MISMATCH=yes SYSSRC=/tmp/sources modules make[1]: Entering directory '/tmp/sources'
Where did you set KERNEL_DIR?
Also, I find this curious: * Found kernel source directory: * /usr/src/linux-5.10.25-gentoo * Found kernel object directory: * /path/to/kernel_build * Found sources for kernel version: * 5.10.25-gentoo For me it doesn't mention object directory: * Determining the location of the kernel source code * Found kernel source directory: * /tmp/sources * Found sources for kernel version: * 5.11.8-gentoo Are you setting other variables, like OUTPUT_DIR?
Ah, I suspect this is related (from linux-info.eclass) # See if the kernel dir is actually an output dir. #454294 if [ -z "${KBUILD_OUTPUT}" -a -L "${KERNEL_DIR}/source" ]; then KBUILD_OUTPUT=${KERNEL_DIR} KERNEL_DIR=$(readlink -f "${KERNEL_DIR}/source") KV_DIR=${KERNEL_DIR} fi Do you have a /source symlink in your kernel dir? Can't say it's a setup I knew was used.
Replacing: BUILD_PARAMS='NV_VERBOSE=1 IGNORE_CC_MISMATCH=yes SYSSRC="${KERNEL_DIR}"' by BUILD_PARAMS='NV_VERBOSE=1 IGNORE_CC_MISMATCH=yes SYSSRC="${KV_DIR}" SYSOUT="${KV_OUT_DIR}"' Should fix your issue, feel free to try if you can until this gets in the tree. Thanks for reporting.
(In reply to Ionen Wolkens from comment #3) > Where did you set KERNEL_DIR? I only set KERNEL_DIR in make.conf, no other variables. Am I set it in the wrong place? It's just works before. here is how i build my kernel (in zsh, omit the sudo -u): cd /path/to/kernel_build make mrproper setopt extendedglob rm -r ^certs make -C /usr/src/linux O=${PWD} nconfig make -j9 make modules_install install emerge @module-rebuild dracut --kver=$(make kernelversion) grub-mkconfig -o /boot/grub/grub.cfg I do have a source symlink in the /path/to/kernel_build directory, $ stat source File: source -> /usr/src/linux-5.10.25-gentoo Size: 29 Blocks: 0 IO Block: 4096 symbolic link and I have a custom pre_pkg_preinst function in the /etc/portage/env to sign the module, but it only happened after the build.
(In reply to OwenJia from comment #7) > make -C /usr/src/linux O=${PWD} nconfig Yes, using O= is the bit I hadn't thought about. The previous fix I mentioned is for this. Rather than kernel sources not being set right, it's the output dir that wasn't.
