cuda gdb带推力碰撞（cuda 5.5版）

我有以下简单的推力：：聚集程序（直接取自推力：：聚集文档）

下一步，我尝试在首先将其连接到cuda gdb后运行此简单程序：

正如Talonmes所指出的，问题在于，使用调试构建时，推力库不能正确运行。在我的应用程序中，我有一个相当复杂的.cu文件，其中包含我自己的几个CUDA内核，以及多个推力调用。如果我用-g-g调试标志编译这个文件并在CUDAGDB内部运行，它将崩溃——这使我无法调试内核

由于我不关心如何调试推力调用本身（仅我的内核），因此我的解决方案涉及将我的所有推力调用放在另一个文件structhwrappers.cu中，并在不进行调试的情况下编译此文件。然后在我的main.cu文件中，我将用相关的包装函数（在StruthWrappers中定义）替换对推力的调用。比如说,

thrust::reduce(...)

变成

thrust::reduce_wrapper(...)

---

然后我会将两个生成的对象文件链接在一起。

众所周知，为调试而构建的推力无法正确编译和运行。我不知道，谢谢。你建议我如何调试一个更大的CUDA程序，其中嵌入了几个推力调用（我不想调试推力内核本身，只调试我自己的内核，问题是程序中的推力调用会导致CUDA gdb崩溃）？我想我可以把我所有的推力调用放在它自己的.cu文件中，并在没有-G标志的情况下编译它。我的其余代码可以通过调试编译如果您运行的是开普勒GPU，您可以尝试将推力代码拆分为自己的源文件，并使用单独的投诉模式。用优化和调试符号来增强你的主旨，并将它们联系在一起。我不知道这是否行得通，但它可能值得探索。你能补充一下，作为一个简短的回答吗？这样你就可以把解决方案留给下一个有同样问题的人。您也可以接受您的oen答案，这将使其从未回答的问题列表中删除，并使搜索更容易找到。
