升级gdb以在Qt Creator中使用 [英] Upgrading gdb for use in Qt Creator

问题描述

最新版本的Qt安装gdb版本7.1。这有一个恼人的错误：它将某些完美有效的表达式评估为<不可用的同步数据> 。显然这已经在gdb 7.2版中得到了修复，所以我下载了最新的gdb.exe并将它复制到 Qt \pythongdb\gdb-i686-pc-mingw32.exe 。唉，这不是成功的：枚举被评估为< anonymous enum> ，而不是（比如） myHelpfulEnumVal ，和（void *）p 被评估为 void * 而不是（比方说） cbf56e0 。所以我回到了gdb版本7.1。

是否有人知道我还有什么要把gdb 7.2与Qt Creator集成？或者它还没有实现？

我在Windows 7下使用minGW。

更新我完成了Stephen Chu建议，现在我正在使用Qt Creator 2.2和gdb 7.2。它似乎工作正常。但是我必须弄清楚如何告诉Qt Creator在哪里可以找到gdb，因为这样做的方式已经改变了：转到 Tools - >选项 - >工具链。你应该可以看到（至少，我在Windows下使用mingw）一个自动检测列表和一个手动列表。 手册列表包含一个单独的项目：

MinGW来自Simulator Qt for MinGW 4.4 Qt SDK）

点击此处，您可以输入 gdb 在调试器：字段中。在我的情况下，这是

C：\ Qt\qtcreator-2.1.81\pythongdb\gdb-i686-pc- mingw32.exe

Creator 2.2包含gdb 7.2。因此，您可以在此下载并尝试快照： ftp://ftp.qt.nokia。 com / qtcreator / snapshots / latest /

我不知道您是否可以从2.2复制gdb并在2.1中使用它。但值得一试。我使用2.2快照，因为它现在足够稳定。

The latest version of Qt installs gdb version 7.1. This has an annoying bug: it evaluates certain perfectly valid expressions as <unavailable synchronous data>. Apparently this has been fixed in gdb version 7.2, so I downloaded the latest gdb.exe and copied it to Qt\pythongdb\gdb-i686-pc-mingw32.exe. Alas, this was not a success: enums were evaluated as <anonymous enum> instead of (say) myHelpfulEnumVal, and (void*)p was evaluated as void* instead of (say) cbf56e0. So I reverted to gdb version 7.1.
Does anybody know what else I have to do to integrate gdb 7.2 with Qt Creator? Or is it simply not implemented yet?
I am using minGW under Windows 7.

Update I have done as Stephen Chu suggests, and am now using Qt Creator 2.2 with gdb 7.2. It seems to work fine. But I had to work out how to tell Qt Creator where to find gdb, because the way to do this has changed: Go to Tools -> Options -> Tool Chains. You should see (at least, I did, using mingw under Windows) an Auto-detected list and a Manual list. The Manual list contains a single item:

MinGW from Simulator Qt for MinGW 4.4 (Qt SDK)

Click on this, and you can enter the path to gdb in the Debugger: field. In my case, this is

C:\Qt\qtcreator-2.1.81\pythongdb\gdb-i686-pc-mingw32.exe

解决方案

Creator 2.2 includes gdb 7.2. So you can download and try the snapshots here: ftp://ftp.qt.nokia.com/qtcreator/snapshots/latest/

I don't know if you can copy the gdb from 2.2 and use it in 2.1. But it's worth a try. I use 2.2 snapshots since it's stable enough right now.
