如何在 GDB 中打印 C++ 向量的元素?
我想检查 GDB 中 std::vector 的内容，我该怎么做?为了简单起见，假设它是一个 std::vector.
I want to examine the contents of a std::vector in GDB, how do I do it? Let's say it's a std::vector<int> for the sake of simplicity.
推荐答案
要查看 vector std::vector myVector 内容，只需输入 GDB:
To view vector std::vector myVector contents, just type in GDB:
(gdb) print myVector
这将产生类似于以下内容的输出:
This will produce an output similar to:
$1 = std::vector of length 3, capacity 4 = {10, 20, 30}
要实现上述目标，您需要有 gdb 7(我在 gdb 7.01 上测试过)和一些 python 漂亮打印机.gdb wiki 上描述了这些的安装过程.
To achieve above, you need to have gdb 7 (I tested it on gdb 7.01) and some python pretty-printer. Installation process of these is described on gdb wiki.
更重要的是，在上面安装之后，这可以很好地与 Eclipse C++ 调试器 GUI(以及我认为的任何其他使用 GDB 的 IDE)配合使用.
What is more, after installing above, this works well with Eclipse C++ debugger GUI (and any other IDE using GDB, as I think).
