问题描述

我的编译失败在ubuntu 12.10与300mb内存可用（总共750mb，350mb到MySQL），1.5ghz，我试图重构wt的基本hello世界文件到一个简单的ajax页面。我确定这不是一个内存问题，因为我能够编译原始的hello.C文件与 g ++ -O3 -o hello hello.C -lwtfcgi -lwt -lboost_signals 。

My compilation fails on ubuntu 12.10 with 300mb memory available (750mb total, 350mb to MySQL), 1.5ghz, I am trying to rework wt's basic hello world file into a simple ajax page. I'm pretty sure it's not a memory issue at heart since I was able to compile the original hello.C file with g++ -O3 -o hello hello.C -lwtfcgi -lwt -lboost_signals.

我确定我在拧紧c ++，因为我撕掉了HelloApplication :: HelloApplication（const WEnvironment& ; env）：WApplication（env）并放在来自Wt :: Json示例的示例中

I'm sure I'm screwing up the c++ since I ripped out the guts of HelloApplication::HelloApplication(const WEnvironment& env) : WApplication(env) and put in the example from the Wt::Json example

HelloApplication::HelloApplication(const WEnvironment& env)
  : WApplication(env)
{
    Json::Object result;
    Json::parse("{ "
             "  \"a\": \"That's great\", "
             "  \"b\": true "
             "}",
             result);

    std::cerr << "Size: " << result.size(); << std::endl; // Size: 2
    WString s = result.get("a");
    bool b = result.get("b");
    std::cerr << "a: " << s << ", b: " << b << std::endl; // a: That's great, b: true
}

，所以我几乎不知道我在做什么。我可以做的是执行最简单的c ++文件。

I'm new to c++, so I have almost no idea what I'm doing. All I can do is execute the simplest of c++ files.

这是最初的。

这里是我获得的json示例。

Here's where I got the json sample from.

** Repercussions**

哇，我的尊重程度刚刚通过了c ++的力量。

Wow, my respect level just went through the roof for the power of c++.

毁了我的VPS。我无法重新启动。我甚至不能重新安装我的发行版。

This has totally destroyed my VPS. I can't restart. I can't even reinstall my distro.

当我终于开始生产时，我想我将建立一个完全不同的开发系统，以防止像这样

When I finally go into production, I think I'm going to set up a totally different dev system to prevent something like this killing my production system.
