在Yocto Rocko中为Beaglebone Black安装禁用Mender

Question

我正在尝试使用Yocto 2.4 (rocko)为beaglebone black构建一个linux镜像，但遇到了一些麻烦。似乎已经添加了一个名为mender的新功能来处理更新。我不想或不需要这个功能，它导致我无法构建。

在尝试构建core-image-minimal时，我得到以下错误：

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

我的bblayers.conf看起来是这样的：

# 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 \
  "

我相信我能够在以前的版本(pyro 2.3)中使用这些设置进行编译。似乎这个修理工才是问题的起因。

我如何禁用它，这样它就不会尝试使用它了？

Answer 1

正确的方法是在meta-bbb中屏蔽(隐藏) recipes-mender目录。它在local.conf.sample 1中进行了描述-请参阅BBMASK变量。如果你很好奇，这里还有一个启用了补丁的local.conf.mender-sample配置示例。

所以只需将这些代码行复制到您的local.conf

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

Answer 2

如果不需要meta-mender，可移除meta-bbb图层中的recipes-mender目录，并检查文件vi meta-bbb/conf/layer.conf.
