Question

不需要是一个完整的调试器，但我需要在引发assert时获得良好的堆栈跟踪转储。一个简单的被调用函数列表是不够的。我对我的埃菲尔系统非常满意，它给了我类似的东西

这意味着我获得了所有堆栈变量和当前（this）对象的转储。最好的是我可以将其发送给客户，因为它需要在客户端进行零配置。

有谁知道我怎样才能在C ++ / C甚至D或CObject中做到这一点（我还是要切换语言，这是我的四个首选目标）？

每个说我应该部署GDB的人都会得到帮助。

Answer 1

对于Windows，请查看minidump，使用toolhelp.dll中的方法创建

Answer 2

如果您使用glibc在Linux上，请查看“backtrace()”函数。我已经在PPC系统上使用它来在发生严重错误时获得堆栈跟踪。

在我的实现中，我只记录返回地址并使用主机平台上的脚本（基于addr2line）将其转换回文件名/函数名/行号。

Answer 3

正如stijn指出的那样，在Windows下，一个小型转储可能就足够了。如果是的话，它几乎可以比任何替代方案容易得多。

minidump不会非常接近你从埃菲尔得到的东西。如果你需要更接近的东西，你可能必须自己编写（大部分）代码。 Antex Stack Walker可能是一个合理的开始（查找stackwalker.cpp和stackwalker.h）。

Answer 4

您可能需要查看google-breakpad：http://code.google.com/p/google-breakpad/

这个项目以前称为安全气囊：

我会承认我没有使用过它（我对这类产品的需求仅限于Windows），但它似乎背后有Mozilla，而且看起来非常活跃。

这是一组自动将故障转储发送到服务器的库和工具，因此您可以进行验尸。据我所知，Firefox目前正在使用它，所以我认为它是非常跨平台的。缺点是它在客户端程序中不是自包含的 - 您需要一些基础设施才能使其有用。这可能适用于您的情况，也可能不适用。

虽然如果您不想获得获取报告的服务（可能您只是想在客户端上使用它们或通过电子邮件发送它们），我想您可以让客户端记者将其信息发送到“服务器”客户端计算机上也存在用于执行报告的程序。不知道让它像这样起作用会有多少工作。
