创建用于构建32位应用程序的工具包

Question

我需要使用将在Linux中运行的QT构建32位应用程序。我想因此我应该管理用于构建32位二进制文​​件的工具包。目前只有一个套件我已经构建了64位的套件。

为了编译32位应用程序，应该在此工具包中进行哪些更改？

我试图再次运行QT安装以安装QT Maintainency  工具。我希望我会在它的帮助下添加套件。我发现安装程序正计划安装QT indirectory我没有/home/g/Qt。我害怕在我的电脑上搞两个QT安装

安装32位库也没有给出任何内容：

sudo aptitude install glibc-devel.i386 libstdc ++ - devel.i386 qt5-qtbase-devel.i386

输出：

您需要先安装32位系统＆amp; Qt库。对于centos / redhat，这就像

yum -y install glibc-devel.i386 libstdc++-devel.i386 qt5-qtbase-devel.i386

其他系统应该类似。

然后将Qt mkspec设置为套件中的linux-g++-32
