Question

我试图通过eglfs而不是X11或wayland运行Qt5框架。我尝试根据yocto Raspberry pi 3为qemuarm emualting Rocko安装Qt5。这是我的bblayers.conf：

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

BBPATH = "${TOPDIR}"
SRCPATH = "/home/yocto/yocto"
BBFILES ?= ""

BBLAYERS ?= " \
    ${SRCPATH}/meta \
    ${SRCPATH}/meta-poky \
    ${SRCPATH}/meta-openembedded/meta-oe \
    ${SRCPATH}/meta-openembedded/meta-multimedia \

我正在尝试构建此图片bitbake rpi-hwup-image

问题在于qtbase，它失败并出现此错误：

| ERROR: Feature 'opengl-desktop' was enabled, but the pre-condition '(config.win32 && !config.winrt && !features.opengles2 && (config.msvc || libs.opengl))
|                           || (!config.watchos && !config.win32 && libs.opengl)' failed.
| 
| ERROR: The OpenGL functionality tests failed!
| You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
| QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

更新

通过取消注释PACKAGECONFIG_append_qtbase来解决此问题，并且它有一个拼写错误，因此已更新为PACKAGECONFIG_append_pn-qtbase。

我也添加了这些行： PACKAGECONFIG_append_pn-qemu-native = " sdl" PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"。

我注释掉了这一行LICENSE_FLAGS_WHITELIST = "commercial"。

但它在qtbase构建时再次因此错误而失败（这是日志文件的尾部）（我删除了tmp文件夹并再次启动bitbake rpi-hwup-image但是它出现了同样的错误）< / p>

Answer 1

我根据此page找到了解决方案。

配置部分 - 在此页面 - 说明了在此选项<html> <head> <title>Companies Form</title> </head> <body> <h1> Please enter below details </h1> <form action="" method="POST"> {{ form.csrf_token }} {{ form.first_name.label }} {{ form.first_name }} {% for l in form.companies() %} {{ l.form.company_name }} {{ l.form.location }} {% endfor %} </form> </body> </html>中省略测试部分的内容，它是在-nomake tests的编译阶段失败的相同部分。所以在清理qtbase并将此部分添加到我的qtbase

之后

local.conf

PACKAGECONFIG_remove_pn-qtbase = " tests gl"也被省略，因为我们要为gl构建qtbase而不是桌面。

无法通过Yocto项目为qemuarm构建Qt5框架
