在ubuntu20中遇到了该问题，换了 ubuntu14就可以了
ubuntu20上的解决方案
以上错误显然是环境问题造成。
根据错误提示：
dialogs/qprintdialog_unix.cpp:281:19: error: ‘class Ui::QPrintPropertiesWidget’ has no member named ‘cupsPropertiesPage’
打开文件dialogs/qprintdialog_unix.cpp
搜索 cupsPropertiesPage
找到这两个地方有调用到
可以看到跟QT_NO_CUPS 有关
配置选项带有-no-cups
从代码中可以分析倒不是这句引起的，需要往上找widget的类型
ui文件中有包含cupsPropertiesPage成员，为啥会提示没有？难道没有编译ui文件？难道跟make工具有关？换了下make3.8.1的后问题依然存在。
那是什么原因导致ui文件没成功被编译的？

Ubuntu20 交叉编译 Qt4.8 报错处理__圣_的博客-CSDN博客_ubuntu交叉编译qt
QT设计器设计的窗口部件，通过 uic 工具转换成C++代码。
用qt5.12.10带的uic替换后出现新的错误
使用旧版gcc
1、安装gcc7并切换版本，使用update-alternatives进行版本切换，输入以下命令：
sudo apt-get install gcc-7 g++-7
# update-alternatives: --install 需要 <链接> <名称> <路径> <优先级>
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 100
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 50
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 100
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-9 50
查看gcc的默认版本，可以看到当前默认gcc版本为7，即切换成功。
sudo update-alternatives --config gcc
查看当前gcc命令的软链接
ls -liat /usr/bin/gcc
ls -liat /usr/bin/g++重新配置和编译qt

QMAKE_CXX = arm-linux-g++ -lts
QMAKE_LINK = arm-linux-g++ -lts
QMAKE_LINK_SHLIB = arm-linux-g++ -lts
