如何在 Yocto 中为 Raspberry PI 构建 Qt5 SDK？

Question

我正在尝试构建 meta-toolchain-qt5。但是，我收到这些错误。我正在按照指南 - Guide Qt5 build

这是我到目前为止所做的事情 -

内部狭小 -

$git clone https://github.com/meta-qt5/meta-qt5.git

后来，我变了

conf/bblayers.conf

POKY_BBLAYERS_CONF_VERSION = "2"

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

BBLAYERS ?= " \
  /home/ABC/TSR/yocto_demo/poky/meta \
  /home/ABC/TSR/yocto_demo/poky/meta-poky \
  /home/ABC/TSR/yocto_demo/poky/meta-yocto-bsp \
  /home/ABC/TSR/yocto_demo/poky/meta-raspberrypi \
  /home/ABC/TSR/yocto_demo/poky/meta-qt5 \
  "

接下来，我在conf/local.conf

中追加了

EXTRA_IMAGE_FEATURES = "debug-tweaks ssh-server-openssh "

IMAGE_INSTALL_append = " gcc g++ binutils libgcc libgcc-dev libstdc++ libstdc++-dev libstdc++-staticdev \

DISTRO_FEATURES_remove = "x11 wayland"

现在，构建之后，我收到以下错误 -

$bitbake meta-toolchain-qt5

Answer 1

你有两个选择

First

tslib 由 meta-oe 层提供，因此您需要获取该层并将其添加到您的 BBLAYERS 所以在您的 poky 树中

git clone git://github.com/openembedded/meta-openembedded

在 conf/bblayers.conf 中将以下内容添加到 BBLAYERS 列表

 /home/ABC/TSR/yocto_demo/poky/meta-openembedded/meta-oe

Second

在您的图层中为 qtbase 添加一个 bbappend 文件，例如 qtbase_%.bbappend

PACKAGECONFIG_remove = "tslib"
