当你遇到“error: undefined reference to vtable for”这样的编译错误时,这通常表示编译器在链接阶段未能找到某个类的虚函数表(vtable)的定义。这个错误常见于使用C++的面向对象特性,特别是涉及到虚函数和继承时。以下是一些可能的原因和相应的解决方案: 可能的原因 未实现基类中的纯虚函数: 如果基类中有纯虚函数...
C++:undefinedreference tovtable原因与解决办法 最近在写一套基础类库用于SG解包blob字段统计,在写完了所有程序编译时遇到一个郁闷无比的错误: MailBox.o(.text+0x124): In function `CMailBox::CMailBox[not-in-charge](CMmogAnalyseStatManager*)': ../src/MailBox.cpp:27: undefined reference to `CSgAna...
undefined reference to typeinfo - C++ error message There are some compiler and loader error messages that shout obviously as to their cause, but there are others that simply don't give the new user much of an indication as to what's really wrong. And most of those I get to know pretty...
But if I include the declaration ('bool Method(struct x, struct y)') in the subclass implementation, I get the 'undefined reference to vtable' error. How do I make the method inheritable by the subclasses so each subclass doesn't repeat the same implementation?
public: virtual bool fun(); } class b:public a { virtual bool fun(){cout << "I am b" << endl;} } 以上代码编译时会报错undefined reference to vtable XXX 修改为: class a { public: virtual bool fun(){cout << "IamA" << endl;}; ...
Mais, je réalise un appel du constructeur de la classe SDL::Window dans SDL::WindowGL car cette dernière hérite publiquement de SDL::Window, or cet appel me renvoie l'erreur "undefined reference to `vtable for WindowGL". Pour info, je code en C++17 avec le paquet build-essential ...

搜索“vtable for”时总是搜到Qt出现的undefined reference to `vtable for`,找不到问题所在,一筹莫展。将编译环境从slack ware换到SLES,还是出现同样的错误。仔细看看,所有obj文件都已正常生成,是在链接成bin文件的时候出错的。再从错误信息中找没有搜索过的关 键词来搜索,尝试了许多关键词后终于在搜索“...

undefined referenceto`vtableforMainWindow' 原因:源文件的目录结构有问题?? 解决方法: 将目录结构不分为include、lib等。直接放在一个文件下,不论是*.ui、*.cpp、*.h等。 2019.10.15更新: 最新一次发生该情况时,试着将含有qt特征文件(含有qt的mainwindow等特征性)放置在src下,而include、lib等另做处理,程序...
