Question

中找到了这些行

要使Qt Web Engine编译为5.6，我需要删除这些行。因为我不知道为什么qtwebengine-qmlplugins，qtwebengine-plugins和qtwebengine-examples都从构建中消失了。所以当这些行尝试从插件目录中删除文件时。它返回错误。

有人可以解释一下他们是什么意思吗？特别是sed一个。 Qt WebEngine 5.6中的Qtwebengine插件，qmlplugins和示例发生了什么？

do_install_append() {
    rmdir ${D}${OE_QMAKE_PATH_PLUGINS}/${BPN} ${D}${OE_QMAKE_PATH_PLUGINS} || true
    sed -i 's@ -Wl,--start-group.*-Wl,--end-group@@g; s@-L${B}[^ ]* @ @g' ${D}${libdir}/pkgconfig/Qt5WebEngineCore.pc
}

修改：这是编译错误

修改：我发现还有一个额外的/ .../hio-imx6dl-board//usr/include...。我已移除/中的OE_QMAKE_INCDIR_QT='${STAGING_DIR_TARGET}/${OE_QMAKE_PATH_HEADERS}'，但仍然会遇到相同的错误。

由于缺少dbus，可能出现多个解决方案而发生此错误：

将dbus添加到您的图片中。
将行添加到qtwebengine_git.bb：DEPENDS += "dbus"
