Catia二次开发CAA编译报“无法解析的外部符号”错误

Q：编译CAA工程时，报错误：

## start step: link2nd   at 09/02/2024-10:59:13
# make: CAAFrame\CAAModule.m win_b64\code\bin\CAAModule.dll
CatiaHelper.obj : error LNK2019: 无法解析的外部符号 "private: void __cdecl CATIRedrawEvent_var::__CastTo(struct IUnknown *)" (?__CastTo@CATIRedrawEvent_var@@AEAAXPEAUIUnknown@@@Z)，该符号在函数 "public: __cdecl CATIRedrawEvent_var::CATIRedrawEvent_var(class CATBaseUnknown_var const &)" (??0CATIRedrawEvent_var@@QEAA@AEBVCATBaseUnknown_var@@@Z) 中被引用

 A：找到无法解析的命令，这里找到CATIRedrawEvent所在的头文件，然后找到对应的库，再在IdentityCard.h文件里定义即可：

在项目中找到并编辑文件IdentityCard.h，然后添加代码：

AddPrereqComponent("ObjectModelerBase",Public);
AddPrereqComponent("ObjectModelerBaseUI",Public);
AddPrereqComponent("ObjectModelerCATIA",Public);
AddPrereqComponent("ObjectModelerCATSDM",Public);
AddPrereqComponent("ObjectModelerCollection",Public);
AddPrereqComponent("ObjectModelerInterfaces",Public);
AddPrereqComponent("ObjectModelerNavigator",Public);
AddPrereqComponent("ObjectModelerSDM",Public);
AddPrereqComponent("ObjectModelerSystem",Public);

重新编译即可。
