更新yocto morty到thud后内核编译错误

Question

我在约克托·莫蒂上使用“linux-toradex-4.1-2.0.x-imx”，一切都很好。但是在更新所有层和poky到“Thud”版本后，我得到内核do_compile错误：

内核配方是：

require recipes-kernel/linux/linux-imx.inc
include conf/tdx_version.conf

SUMMARY = "Linux kernel for Toradex Freescale i.MX based modules"

SRC_URI = "git://[e-mail]/kernel/linux-toradex-4.1-2.0.x-imx.git;protocol=ssh;branch=${SRCBRANCH} \

# Load USB functions configurable through configfs (CONFIG_USB_CONFIGFS)
KERNEL_MODULE_AUTOLOAD += "${@bb.utils.contains('COMBINED_FEATURES', 'usbgadget', ' libcomposite', '',d)}"

LOCALVERSION = "-${TDX_VER_ITEM}"
# PV_append = "+git${SRCPV}"

SRCREV = "e420b7a49300560485af191ec63887d27da577db"

DEPENDS += "lzop-native bc-native"
COMPATIBLE_MACHINE = "(mx7|mx6)"

# defaults
TDX_VER_ITEM ??= "0"

inherit kernel

在'meta-toradex-nxp'层，我只看到'linux-toradex_4.9-2.3.x.bb'而不是4.1-2.0. x，这很重要吗？我是否需要在我的使用'Thud'编译的配方中添加其他内容？

我的bblayers.conf也是：

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "7"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

提前非常感谢你。

更新：感谢@Marcel，我查看了yocto手册，它说：“GNU编译器集合版本8.2现在默认用于编译。如果您仍然需要使用版本7.x进行编译，还提供了GCC 7.3。您可以通过设置来选择此版本，也可以通过在配置中将GCCVERSION变量设置为“7.%”来选择。”

然后我插入'GCCVERSION="7.%"'到conf/local.conf，但不幸的是它仍然不工作。

请注意，Thud正在使用更高版本的gcc编译器（准确地说是8.3）。不幸的是，过时的Linux内核4.1无法使用gcc 8.3进行编译，您需要将多个补丁向后移植才能使这种组合工作。另外请注意，OpenEmbedded通常将任何警告视为错误，您可能还希望通过编译标志禁用该警告。否则，所需的补丁数量将是无限的。总的来说，更好的方法可能是适当地采用稍后仍然支持的Linux内核，如我们现在正式在BSP 3.0b2中使用的toradex_4.14-2.0.x-imx。
