Question

好的，在我的XPCOM组件迁移到Gecko 2.0之后，我修好了几个如下： 1.将#include“nsIGenericFactory.h”替换为#include“mozilla / ModuleUtils.h” 2.将xpcomglue_s.lib替换为xpcomglue_s_nomozalloc.lib 3.将#include“mozilla-config.h”添加到xpcom-config.h头文件中 4.以及删除一些未使用的头文件，例如：nsReadableUtils.h，nsEventQueueUtils.h，nsIExtensionManager.h 5.将NS_DEFINE_STATIC_IID_ACCESSOR（IMYPROGRAM_IID）替换为NS_DEFINE_STATIC_IID_ACCESSOR（IMyProgram，IMYPROGRAM_IID）

现在从200多个错误减少到20多个，下面是一些错误，我不知道那是什么，这里有任何专家遇到如下问题吗？

Answer 1

至少看起来你的界面中缺少一个NS_DECLARE_STATIC_IID_ACCESSOR(IMYPROGRAM_IID)（xpidl会自动为你生成它。）如果没有源代码，其他一些错误有点难以理解，但很可能你还没有完全正确地更新你的模块注册码。
