【中文标题】Qt 4.8.4 Release 版本不适用于 Windows 7 64 位【英文标题】：Qt 4.8.4 Release version not working on Windows 7 64 bit 【发布时间】：2013-10-14 20:39:37 【问题描述】：

我正在尝试制作项目的可发布版本。我在几台不同的机器上使用包含在同一目录中的 dll 测试了 exe。它在我的电脑（windows 8 64 位）、32 位 windows xp 虚拟机、32 位 windows 7 虚拟机和另一台 windows 7 64 位笔记本电脑上运行。然而，其他人正试图在另一台 Windows 7 64 位机器上运行它。他收到一个 Microsoft Visual C++ 运行时库错误，上面写着：

此应用程序已请求运行时以异常方式终止。请联系应用程序的支持团队了解更多信息。

我包含在应用程序目录中的 dll：

libgcc_s_dw2-1.dll
libstdc++-6.dll
mingwm10.dll
QtCore4.dll
QtCored4.dll
QtGui4.dll
QtNetwork4.dll
QtSerialPortd.dll

这是 exe 文件上的 ldd 在我正在运行的 Windows 8 计算机上的样子：

【参考方案1】：

为您提供 Microsoft Visual C++ 运行时库的计算机上是否安装了 Microsoft Visual C++ 可再发行软件包？任何没有用于构建程序的编译器版本相同的计算机都需要安装 redist 包，以便可执行文件可以在运行时加载这些库。

This page 有各种可下载的 redist 包的链接。

此外，在您的分布式 DLL 列表中，您同时拥有 QtCore4.dll 和 QtCored4.dll。带有 'd' 的那个是一个调试 DLL，不会被您的 Release 构建的可执行文件加载。您也只是分发 QtSerialPortd.dll 的调试版本，因此您也应该将其切换到发布版本（去掉“d”）。

比较能工作的 Windows 7 64 位和不能工作的... C++ 2010 x86 Redistributable”以及 x64 Redistributable。不工作的机器只有“Microsoft Visual C++ 2010 x64 Redistributable”，没有x86 Redistributable。过去遇到过类似的问题，Dependency Walker 对解决这些问题很有帮助。 Jared，如果您将程序构建为 32 位可执行文件（看起来您肯定必须考虑到它在 32 位机器上运行），那么就没有 x86 Redistributable 包很可能是问题所在。尝试安装 x86 Redist 软件包，看看是否能解决问题。【参考方案2】：

嗯，我想通了。这是 DB9 串行 com 端口的问题。

应用程序使用串行端口连接到设备。它不工作的计算机上有一个旧的 DB9 串行端口。其他电脑只有 USB 端口。当我们插入 DB9 串行电缆时，应用程序运行良好。

有一些 3rd 方库处理一些串行端口的东西，所以我得看看。
