The kernel tries to define the LINUX_COMPILER macro from the output of `$(CC) -v | grep ' version '`, but in clang that might produce more than one line containing ' version ' when CUDA is installed: ``` Android (8490178, based on r450784d) clang version 14.0.6 Found CUDA installation: /usr/local/cuda, version 11.0 ``` That causes the macro to expand into multiple lines, upsetting the compiler that cannot find the ending double quote. In upstream linux this is fixed from v5.8 Change-Id: Icde4253e989df1cbbefc0ce98f437d16822fc93b

# Configuration
|

# =============

|
# These config vars are usually set in BoardConfig.mk:

|
#
|
|
# TARGET_KERNEL_ADDITIONAL_FLAGS = Additional make flags, optional
|
|
# TARGET_KERNEL_CONFIG = List of kernel defconfigs, first one being the base one,
|
|
# while all the others are fragments that will be merged
|
|
# to main one in .config.
|
|
# TARGET_KERNEL_RECOVERY_CONFIG = Same as above, but applicable to recovery kernel instead.
|
|
# TARGET_KERNEL_VARIANT_CONFIG = Variant defconfig, optional
|
|
# TARGET_KERNEL_SELINUX_CONFIG = SELinux defconfig, optional
|
|
#
|
|
# TARGET_KERNEL_CLANG_COMPILE = Compile kernel with clang, defaults to true
|
|
#
|
|
# BOARD_KERNEL_IMAGE_NAME = Built image name
|
|
# for ARM use: zImage
|
|
# for ARM64 use: Image.gz
|
|
# for uncompressed use: Image
|
|
# If using an appended DT, append '-dtb'
|
|
# to the end of the image name.
|
|
# For example, for ARM devices,
|
|
# use zImage-dtb instead of zImage.
|
|
#
|
|
# BOARD_DTB_CFG = Path to a mkdtboimg.py config file for dtb.img
|
|

|
|
#
|
|
# KERNEL_CC = The C Compiler used. This is automatically set based
|
|
# on whether the clang version is set, optional.
|
|
#
|
|
# KERNEL_CLANG_TRIPLE = Target triple for clang (e.g. aarch64-linux-gnu-)
|
|
# defaults to arm-linux-gnu- for arm
|
|
# aarch64-linux-gnu- for arm64
|
|
# x86_64-linux-gnu- for x86
|
|
#
|
|
# KERNEL_LTO = Optional, force LTO to none / thin / full
|
|
#
|
|
# NEED_KERNEL_MODULE_ROOT = Optional, if true, install kernel
|
|
# modules in root instead of vendor
|
|
# NEED_KERNEL_MODULE_SYSTEM = Optional, if true, install kernel
|
|
# modules in system instead of vendor
|
|
# NEED_KERNEL_MODULE_VENDOR_OVERLAY = Optional, if true, install kernel
|
|
# modules in vendor_overlay instead of vendor
|
|
#
|
|
# TARGET_FORCE_PREBUILT_KERNEL = Optional, use TARGET_PREBUILT_KERNEL even if
|

# kernel sources are present
