buildroot QT5.12.2编译时qwayland报错

gaoshanyun

项目需要QT 5.12.2，编译时qwayland报错，从错误上看是由于补丁0024-qwaylandwindow-Support-setting-window-blocked-state.patch和版本不符合。重复定义这个可以改下，但是下面还有wlSurface的报错
这些补丁不合行不行？或者有其他的解决方法。
另：QT 5.14.2编译时没有报这个错误

好的，我试试。谢谢

采用了遇到错误解决错误的方式解决了这个问题。
1.将QT版本修改为5.12.2， rk356x_linux_release_20211019\buildroot\configs\rockchip\qt.config
BR2_PACKAGE_QT5_VERSION_5_12=y

2.修改qwayland的pro文件，否则不编译插件库。buildroot\output\rockchip_rk3566\build\qt5wayland-5.12.2\src\src.pro
qtConfig(wayland-client) {
    sub_qtwaylandscanner.subdir = qtwaylandscanner
    sub_qtwaylandscanner.target = sub-qtwaylandscanner
    SUBDIRS += sub_qtwaylandscanner

    sub_client.subdir = client
    sub_client.depends = sub-qtwaylandscanner
    sub_client.target = sub-client
    SUBDIRS += sub_client

    /*添加部分*/
    sub_plugins.subdir = plugins
    sub_plugins.depends += sub-qtwaylandscanner
    sub_plugins.depends += sub-client
    sub_plugins.target = sub-plugins
    SUBDIRS += sub_plugins

3.此时编译会报错，将插件中buildroot\output\rockchip_rk3566\build\qt5wayland-5.12.2\src\plugins\hardwareintegration\hardwareintegration.pro


    SUBDIRS += client
    SUBDIRS += compositor /*该行删除*/
    注：项目中没有用compositor


以上笨方法，解决燃眉之急
