nsiCookieManager2 程序缺少符号
请帮助我解决此 MOZILLA 程序缺少的 LIB。 尝试使用 nsICookieManager2 创建 cookie 我已尝试使用 Mozilla SDK 中的所有现有库 问候
C:\Code>cl.exe FFCookie.cpp /I "C:\xulrunner-sdk\include" mozalloc.lib xpcomglue.lib /link /LIBPATH:"C:\xulrunner-sdk\lib"
符号丢失：
FFCookie.obj：错误 LNK2019：无法解析的外部符号“public：void __thiscall nsCOMPtr_base::assign_from_gs_contractid_with_er ror(class nsGetServiceByContractIDWithError const &,struct nsID const &)" (?assign_from_gs_contractid_with_error@nsCOMPtr_base@@QA EXABVnsGetServiceByContractIDWithError@@ABUnsID@@@Z) 中引用 函数“公共：__thiscall nsCOMPtr:: nsCOMPtr（类 nsGetServiceByContractIDWithError const &)" (??0?$nsCOMPtr@VnsICookieManager@@@@QAE@ABVnsGe tServiceByContractIDWithError@@@Z)

cookieManager2->Add(NS_LITERAL_CSTRING("ud.abc.com"),
NS_LITERAL_CSTRING("//"),
NS_LITERAL_CSTRING("TK"),
NS_LITERAL_CSTRING("abc"), 0x1, 0x1, 0, -1);
}
}
return 0;
}
问题：
我没有找到任何关于要包含哪个 LIB 的函数文档信息（正如我在 MSDN 上找到的）
有关如何找出与 MOZILLA 特定函数相对应的 LIB 的任何线索。
Please help me with the missing LIBs for this MOZILLA program.
Trying to create cookie using nsICookieManager2
I have tried with all the existing libs in Mozilla SDK

Questions:
I dont find any info with function documentation regarding which LIB to include (as I find on MSDN)
Any clue on how to figure out LIB corresponding to particular function for MOZILLA.

问题不在于库，缺少的符号是在 xpcomglue 库中定义的。但是，您似乎有一些编译参数与用于编译 XULRunner/Firefox 的参数不匹配。您的编译器正在查找的符号包含“QAEX”作为参数描述，而库则使用“QAIX”定义它们。查看名称修改表，您的编译器需要
unsigned char其中 Mozilla 有unsigned int。我怀疑原因是您在没有 Unicode 支持的情况下编译应用程序 - 将main()更改为wmain()？The problem isn't with the lib, the symbol missing is defined in the
xpcomgluelibrary. However, you seem to have some compile parameters that don't match the parameters used to compile XULRunner/Firefox. The symbols your compiler is looking for contain "QAEX" as parameter description whereas the library defines them with "QAIX". Looking at the name mangling table, your compiler expectsunsigned charwhere Mozilla hasunsigned int. I suspect that the reason is you compiling your application without Unicode support - changemain()intowmain()?
