如何使Qt Creator的调试器在OS X中显示C ++向量的内容？ [英] How do I make Qt Creator's debugger show the contents of C++ vectors in OS X?

问题描述

我正在写一个程序，广泛使用向量，并且正在Mac OS X 10.6.6上首次使用Qt Creator 2.0.1开发。

当我正在调试时，我可以在 Locals and Watchers 窗口中看到文字和数组，但是一旦我去展开一个向量，在这种情况下，类型学生，我得到这个树：

我正在使用的另一个人是在Ubuntu上使用相同版本的Qt Creator，可以看到载体的内容很好。我做错了什么？

这是他的调试器：

解决方案

QtCreator 2.6支持Mac FSF GDB（7.5）支持。 FSF GDB支持python，它允许qtcreator正确显示QVector，QSet，QList，QString等。它可以从macports下载。

1. 下载并安装macports（从这里下载 http://www.macports.org/install.php ）



2. 要安装FSF GDB 7.5：

     sudo port install gdb 
     




3. 给FSF GDB权限调试应用程序：

     sudo codesign -s gdb-cert / opt / local / bin / ggdb 
     

   如果找不到gdb-cert，请点击下面的链接创建一个gdb-cert，然后按照创建证书的说明进行操作：

   如果您没有授予ggdb的权限，您将得到一个：

    无法理解nd进程号28885的Mach任务端口（（os / kern）失败（0x5））。 
   （请检查gdb是否已编码 - 请参阅taskgated（8））
     




4. 更改在QtCreator中的工具箱调试器
   

   
   
   

   将路径从/ usr / bin / gdb更改为/ opt / local / bin / ggdb




5. 默认情况下，FSF GDB无法正确处理断点因为mac clang ++不导出调试符号。要导出调试符号，需要手动运行dsymutil。幸运的是，在使用qmake链接程序后，可以自动运行dysmutil命令。在.pro文件中添加以下行：

     macx {
    CONFIG（debug，debug | release）{
    QMAKE_POST_LINK = dsymutil \MyApp.app/Contents/MacOS/MyApp\
   } 
   } 
     

I'm writing a program that makes extensive use of vectors and am developing with Qt Creator 2.0.1 on Mac OS X 10.6.6 for the first time.

As I am debugging, I can see literals and arrays just fine in the Locals and Watchers window, but as soon as I go to expand a vector, in this case of type Student, I get this tree:

The other person I am working with on this is using the same version of Qt Creator on Ubuntu and can see the contents of the vectors just fine. What am I doing wrong?

This is his debugger:

解决方案

QtCreator 2.6 has support for Mac FSF GDB (7.5) support. FSF GDB supports python which allows qtcreator to properly display QVector, QSet, QList, QString, etc. It can be download from macports.

1. Download and Install macports (download it from here http://www.macports.org/install.php)

2. To install FSF GDB 7.5:

        sudo port install gdb
   

3. Give FSF GDB permission to debug applications:

   sudo codesign -s gdb-cert /opt/local/bin/ggdb
   

   If gdb-cert isn't found, create a gdb-cert by clicking on the link below, and follow the directions for "Creating a certificate":

   http://sourceware.org/gdb/wiki/BuildingOnDarwin

   If you don't give permission to ggdb, you'll get a:

    Unable to find Mach task port for process-id 28885: (os/kern) failure (0x5).
    (please check gdb is codesigned - see taskgated(8)) 
   

4. Change the kit debugger in QtCreator

   Change the path from /usr/bin/gdb to /opt/local/bin/ggdb

5. By default FSF GDB fails to handle breakpoints correctly because mac clang++ doesn't export debug symbols. To export the debugging symbols, dsymutil needs to be run manually. Luckly, dysmutil command can be run automatically after link the program using qmake. Add the following lines in your .pro file:

   macx {
       CONFIG(debug, debug|release) {
           QMAKE_POST_LINK = dsymutil \"MyApp.app/Contents/MacOS/MyApp\"
       }
   }
