我在Qt WebEngine 5.5 和 5.6 配方中找到了这些行
为了使 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。因此，当这些行尝试从插件目录中删除文件时。它返回错误。
有人能解释一下它们是什么意思吗？尤其是那个sed。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
}
编辑：这是编译的错误

编辑：我发现有一个额外的/ .../hio-imx6dl-board//usr/include...。我已经删除了/inOE_QMAKE_INCDIR_QT='${STAGING_DIR_TARGET}/${OE_QMAKE_PATH_HEADERS}' 但仍然得到上面相同的错误。
