c++ - 在 Centos 中安装 QT - 安装 OpenBR 时的 CMake 警告

Question

我正在尝试安装 OpenBR在 CentOS 中。给出的步骤here适用于 Ubuntu。因为我需要在 Centos 中安装 OpenBR 库。我使用的是“Centos-6.5”版本。

以下是 OpenBR 团队要求遵循的安装 QT 的步骤。

sudo apt-get install qt5-default libqt5svg5-dev qtcreator

我应该如何在 CentOS 中安装它。

我遵循了这个 link 中的步骤安装QT。

当我给出此命令时出现以下错误(为了便于查看，我删除了错误)。会是什么问题？

您可以从 EPEL 获得 CentOS 6 的预构建 qt 5 包。首先，安装 EPEL 存储库:

sudo rpm -Uvh \
   http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

然后使用 yum 安装 qtbase devel 模块，以及您可能需要的任何其他模块。

yum install qt5-qtbase-devel
