我有16位的Linux Mint 17.3（Ubuntu 14.04），我无法获得依赖Qt5工作的32位可执行文件。如果我执行它，它会报告
$ ./Program
./Program: error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory
启用系统上的multiarch：
$ dpkg --print-foreign-architectures
i386
并且，即使这似乎是debian multiarch方法取代的解决方案，也安装了ia32-libs。
所以我希望 / usr / lib / x86_64-linux-gnu 中的每个64位库也在 / usr / lib / i386-linux-中安装其等效的32位库。 GNU 。这似乎适用于Qt4库和许多其他库，因为i386目录有很多项，例如 libQtCore.so.4.8.6 。
但是，正如我所说，我想运行一个依赖于Qt5的32位可执行文件，所以我想知道为什么我找不到像 libQt5Widgets.so.5.2.1这样的东西。 i386-linux-gnu / 目录中的，即使在 x86_64-linux-gnu / 似乎安装了包：
$ dpkg -l | grep libqt5
ii libqt5core5a:amd64 5.2.1+dfsg-1ubuntu14.3 amd64 Qt 5 core module
ii libqt5dbus5:amd64 5.2.1+dfsg-1ubuntu14.3 amd64 Qt 5 D-Bus module
ii libqt5gui5:amd64 5.2.1+dfsg-1ubuntu14.3 amd64 Qt 5 GUI module
(...)
我注意到他们指定了amd64，所以我试图引入i386软件包，但是发布了许多似乎没有自动解决的依赖性问题，例如：
$ sudo apt-get install libqt5widgets5:i386

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

E: Unable to correct problems, you have held broken packages.
如果我尝试将缺少的依赖项添加到安装调用中，它会让我陷入一个依赖的兔子洞。 所以最重要的两个问题是：

运行sudo apt-get install libqt5widgets5:i386 -o Debug::pkgProblemResolver=yes会产生以下结果：

也许有人有经验来解释这里发生的事情。为什么困扰这么多的amd64库？
