Mozilla XPCOM未注册 [英] Mozilla XPCOM is not registered

问题描述

我正在尝试为Firefox构建扩展程序.此扩展使用XPCOM组件(C ++ dll).我正在编译DLL，编译正常.

I'm trying to build an extension for Firefox. This extension uses an XPCOM component (a C++ dll). I'm compiling the DLL, compilation is OK.

下一步是在我的扩展程序中使用Javascript中的组件.我添加了代码以从我的c ++文件注册我的组件:

The next step would be to use the component in Javascript from my extension. I added the code to register my component from my c++ file :

static const mozilla::Module::CategoryEntry kSampleCategories[] = {
    { JAVASCRIPT_GLOBAL_PROPERTY_CATEGORY, "greenfox", NS_SAMPLE_CONTRACTID },
};

在清单中，我声明XPCOM:

In my manifest, I declare the XPCOM :

component {03A6D0B4-22B9-11DF-B844-20D556D89593} components/GreenCodeLabFox.dll

问题是，当我尝试在JS中使用该组件时，似乎未注册该组件:

The problem is, when I try to use the component in JS, it seems it is not registered :

    try {
        greenfox;
        return true;
    } catch( e ) {
        alert( e );
        return false;
    }   

这给了我警报错误:

ReferenceError: greenfox is not defined

在错误控制台中，我没有任何消息.

In error console, I have no message.

如果没有错误消息，我该如何调试?顺便说一句，我的javascript.options.showInConsole设置为true.

How would I debug this if I have no error message ? By the way, my javascript.options.showInConsole is set to true.

谢谢！

推荐答案

每 https://developer.mozilla.org/zh-CN/XPCOM/XPCOM_changes_in_Gecko_2.0 必须使用binary-component指令注册二进制组件.

Per https://developer.mozilla.org/en/XPCOM/XPCOM_changes_in_Gecko_2.0 you must use a binary-component directive to register a binary component.

该页面还链接到示例；您只张贴了注册所需代码的一部分.

That page also links to an example; you only posted a part of the code required for registration.

如果该组件仍然无法正常工作，我将尝试通过错误控制台中的Components.classes [ contract id ]来获取它-这将显示问题是否出在组件注册上或仅包含全球财产部分.

If the component still doesn't work, I'd try to get it via Components.classes[contract id] from the Error Console - that will show if the problem is with the component registration or just with the global property part.

https://developer.mozilla.org/zh-CN/Troubleshooting_XPCOM_components_registration 对于故障排除可能很有用，尽管它有点过时了.

https://developer.mozilla.org/en/Troubleshooting_XPCOM_components_registration might be useful for troubleshooting, although it's a bit dated.
