这是我的.classpath文件,在我添加了两个外部jar(org.restlet.ext.simple.jar和org.simpleframework.jar)之后:

这让我编译并运行C++应用程序,但是,我无法调试它.
所以,我使用mingw发行版安装了gdb windows二进制文件.现在,当我尝试调试时,控制台中显示以下消息 - 未加载符号表.使用"file"命令.
我没有受过教育的猜测是,gdb无法调试Visual C++编译器生成的二进制文件.
我的问题是 - 如何在使用Visual C++工具链构建的eclipse中调试C++代码？
我的环境:
谢谢.
PS
转移到MinGW g ++编译器是关于这个问题的范围,所以请 - 不要建议它作为答案.
鉴于:
def f():
x = 0
def g():
h()
def h():
x += 1
print(x)
g()
>>> f()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 8, in f
File "<stdin>", line 4, in g
File "<stdin>", line 6, in h
UnboundLocalError: local variable 'x' referenced before assignment
>>>
如何h查看x变量？
谢谢.
编辑
本来应该提到的,我使用的是Python 2.7.3
现在,我的模块目录被定义为IIS虚拟目录,IIS提供文件.
我想知道IntelliJ是否有一个内部Web服务器,它可以提供文件,而不需要任何第三方.Eclipse 确实如此.
请考虑以下示例代码:
using System.Diagnostics;
using System.Threading.Tasks;
public struct AStruct
{
public int Value;
public async Task SetValueAsync()
{
Value = await Task.Run(() => 1);
}
public void SetValue()
{
Value = 1;
}
}
class Program
{
static void Main(string[] args)
{
Test(new AStruct());
TestAsync(new AStruct()).Wait();
}
private static async Task TestAsync(AStruct x)
{
Debug.Assert(x.Value == 0);
await x.SetValueAsync();
Debug.Assert(x.Value == 0);
}
private static void Test(AStruct x)
{
Debug.Assert(x.Value == 0);
x.SetValue();
Debug.Assert(x.Value == 1);
}
}
注意之间的差异Test和 …
所以,task.Wait()可以转化为await task.当然,语义是不同的,但这大致是我将阻塞代码Waits转换为异步代码的方法awaits.
我的问题是如何转变task.Wait(CancellationToken)为各自的await声明？
找到https://github.com/Reactive-Extensions/Rx.NET/issues/148,但我无法弄清楚底线 - Rx.NET for .NET Core在哪里以及如何获得它？
我正在使用安装了.NET Core的Enterprise Visual Studio 2015 Update 3.
今天我在我的Windows机器上运行git stash -h来获得此响应:
usage: git legacy-stash list [<options>]
or: git legacy-stash show [<stash>]
or: git legacy-stash drop [-q|--quiet] [<stash>]
or: git legacy-stash ( pop | apply ) [--index] [-q|--quiet] [<stash>]
or: git legacy-stash branch <branchname> [<stash>]

[-u|--include-untracked] [-a|--all] [-m <message>]

or: git legacy-stash clear
请再说一遍？legacy-stash？到底是怎么回事？
我使用 VS Code 开发 terraform 代码。我当前的 terraform 插件是：
