redhat安装qt

在Red Hat Enterprise Linux (RHEL) 或其衍生版如CentOS等基于Debian的发行版上安装Qt库，可以分为几个步骤：

1. **更新包列表**:

   sudo yum update -y

2. **添加EPEL存储库**（对于旧版本的RHEL/CentOS）:

   sudo yum install epel-release -y

或者对于新版本的Fedora/RHEL，通常已经包含了EPEL。

3. **安装Development Tools**:

   sudo yum groupinstall "Development Tools" -y

4. **安装Qt Development Kit (SDK)**:
对于Qt 5：

   sudo yum install qt5-devel -y

如果需要Qt 6，可以替换为 `qt6-devel`。

5. **验证安装**:
安装完成后，你可以通过运行 `qmake` 和 `make` 来测试安装是否成功。例如创建一个小的Qt项目目录并初始化：

   mkdir my_qt_project
   cd my_qt_project
   qmake -v  # 显示Qt版本信息

redhat8.9安装qt

Red Hat Enterprise Linux 8.9 (Ootpa) 安装Qt的过程可以分为几个步骤：

1. **更新系统**:
首先，确保你的系统是最新的：

   sudo dnf update

2. **添加软件源**:
如果官方仓库没有包含Qt，需要添加额外的软件存储库，比如EPEL (Extra Packages for Enterprise Linux) 或者RPM Fusion。对于EPEL，运行：

   sudo curl -o /etc/yum.repos.d/epel-release-latest-8.noarch.rpm https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=$basearch
   sudo rpm -Uvh /etc/yum.repos.d/epel-release-latest-8.noarch.rpm

对于RPM Fusion，按照对应版本的文档操作。

3. **安装Qt**:
使用 `dnf` 工具安装 Qt 5：

   sudo dnf install qt5-default qttools5-dev-tools

这将安装基本的Qt库和开发工具。

4. **确认安装**:
安装完成后，你可以通过命令行验证Qt是否已成功安装：

   qmake -v

或者创建一个简单的Qt项目测试一下。
