centos-stream 安装QT

first, install dependency:

yum -y groupinstall "GNOME Desktop"
yum -y groupinstall "Development Tools"
yum install -y libGL libGL-devel
yum install -y mesa-libGL-devel mesa-libGLU-devel freeglut-devel
yum install -y libxcb libxcb-devel libXrender libXrender-devel xcb-util-wm xcb-util-image xcb-util-keysyms xcb-util-renderutil

or ubuntu:

sudo apt install libxrender-dev

sudo apt-get install libgl1 libglx-mesa0

sudo apt-get install libgl1-mesa-dev

sudo apt-get install libglu1-mesa-dev

sudo apt install libxcb-cursor0 libxcb-cursor-dev

 chmod +x qt-unified-linux-x64-online.run
./qt-unified-linux-x64-online.run --mirror https://mirrors.ustc.edu.cn/qtproject

配置环境变量

安装完成后，将Qt的bin目录添加到PATH环境变量中：

在终端中输入以下命令打开.bashrc文件：

vi ~/.bashrc

在文件的末尾添加以下内容：

export QTDIR=/opt/Qt/5.15.2/gcc_64
export PATH=$QTDIR/bin:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

保存并关闭文件后，运行以下命令使环境变量生效：

source ~/.bashrc

验证安装

使用以下命令验证Qt是否正确安装：

qmake --version

安装Qt Creator（可选）

如果需要IDE，可以安装Qt Creator：

sudo yum install qt-creator -y

2、after installed qt, then start qtcreator.

./qtcreator 启动不起来，Could not load the Qt platform plugin "xcb" in "" even though it was found.

ldd libqxcb.so | grep found

yum install libxcb-cursor*

搞定

ibus-setup添加中文输入法，然后在设置-》Keyboard里面点击+ ibus-setup中添加的输入法，然后设置ctrl切换快捷键
