在 Yocto Rocko 中禁用 Mender 以安装 Beaglebone Black

Question

我正在尝试使用 Yocto 2.4 (rocko) 和运行为 beaglebone black 构建一个 linux 图像，但遇到了一些麻烦。似乎添加了一个名为 mender 的新功能来处理更新。我不想要或不需要此功能，这导致我无法构建。

尝试构建 core-image-minimal 时，出现以下错误：

Loading cache: 100% |###############################################################################################################################################################################| Time: 0:00:00
Loaded 2803 entries from dependency cache.
Parsing recipes: 100% |#############################################################################################################################################################################| Time: 0:00:01
Parsing of 2008 .bb files complete (2001 cached, 7 parsed). 2810 targets, 94 skipped, 0 masked, 0 errors.

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

我的 local.conf 看起来是这样的：

MACHINE ??= "beaglebone"
DISTRO ?= "poky"
PACKAGE_CLASSES ?= "package_deb"
EXTRA_IMAGE_FEATURES = "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs"

CORE_IMAGE_EXTRA_INSTALL += "openssh"

CORE_IMAGE_EXTRA_INSTALL += "gnupg"
CORE_IMAGE_EXTRA_INSTALL += "nano"
CORE_IMAGE_EXTRA_INSTALL += "cifs-utils"
CORE_IMAGE_EXTRA_INSTALL += "apache2"

我的 bblayers.conf 看起来像这样：

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

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

BBLAYERS ?= " \
  ${TOPDIR}/../meta \
  ${TOPDIR}/../meta-poky \
  ${TOPDIR}/../meta-yocto-bsp \
  ${TOPDIR}/../meta-openembedded/meta-oe \
  ${TOPDIR}/../meta-openembedded/meta-python \
  ${TOPDIR}/../meta-openembedded/meta-networking \
  ${TOPDIR}/../meta-openembedded/meta-webserver \
  ${TOPDIR}/../meta-bbb \
  ${TOPDIR}/../meta-qt5 \
  "
BBLAYERS_NON_REMOVABLE ?= " \
  ${TOPDIR}/../meta \
  ${TOPDIR}/../meta-poky \
  "

我相信我基本上可以使用以前版本（pyro 2.3）中的这些设置进行编译。看来这个修补程序是问题的根源。

如何禁用它，使其不再尝试使用它？

Answer 1

如果不需要meta-mender可以去掉meta-bbb层的recipes-mender目录，同时检查文件vi meta-bbb/conf/layer.conf.

Answer 2

正确的方法是屏蔽（隐藏）meta-bbb 中的 recipes-mender 目录。它在 local.conf.sample [1] 中进行了描述 - 请参阅 BBMASK 变量。如果您好奇，还有 local.conf.mender-sample 启用修补程序的配置示例。

所以只需将这些行复制到您的 local.conf:

# mask for non-mender builds
BBMASK = "meta-bbb/recipes-mender"
