Mac 安装qt


  • 通过mac的homebrew安装qt
    brew install qt
    此步骤安装完成后,终端会显示安装完成后的最终目录 /usr/local/opt/qt
  • 下载并安装qtcreator 使用homebrew

    brew install qt-creator

    或者 选择需要的版本下载即可

    http://download.qt.io/official_releases/qtcreator/
  • 配置 上面两条命令之间是没有关联的,后装的qt-creator不会自动检测到前面的qt(qt这个包是QT开发工具链),所以需要配置。

通过brew info qt命令,查看详情

==> Caveats
We agreed to the Qt open source license for you.
If this is unacceptable you should uninstall.

qt is keg-only, which means it was not symlinked into /usr/local,
because Qt 5 has CMake issues when linked.

If you need to have qt first in your PATH run:
  echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.bash_profile

For compilers to find qt you may need to set:
  export LDFLAGS="-L/usr/local/opt/qt/lib"
  export CPPFLAGS="-I/usr/local/opt/qt/include"

For pkg-config to find qt you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/qt/lib/pkgconfig"

问题

  • 安装完成后,创建新的项目出现错误No valid kits found., 原因: qtcreator 无法选择Qt版本导致,此时我们需要添加qt版本。 解决方法: 打开qtcreator的偏好设置-Kits-QT versions,点击添加,找到/usr/local/Cellar/qt/5.11.2/bin/qmake文件,添加进去,然后在构建套件的QT 版本选项选择添加的版本即可。

  • 运行项目后报错 Project ERROR: failed to parse default search paths from compiler output. 解决方法: 打开qtcreator的偏好设置-Kits,在构建套件(kit)选项栏,选中桌面,将编译器由gcc修改编译器为Clang。
