“undefined reference to `vtable for” 解决之道
作者:互联网
在C++编译链接过程中,碰到“undefined reference to `vtable for” 有两种排除方法
检查使用的类的基础关系上是否有没有实现的虚函数
示例:
The fix? You've got line(s) like
virtual float getarea() ;
that should read
virtual float getarea() {} ;
The complete (working) source code files for this example are available here
改进建议:在父类里子类会继承重写的成员虚函数加上override;
检查使用的类的库是否被链接
如果没链接,以动态库或者静态库加入到MakeFile 或者CMakeList.txt 中去.示例:
+target_link_libraries(server brpc braft gflags protobuf proto_dbs proto_ebs common log
+configuration your_lib_including_the_code) # add other lib
+link_libraries("../../libs/project_of_your_lib_including_the_code/output/lib")
