The easiest way would be to invoke a single command: g++ Main.cpp Security.cpp However, if you want to compile the files separately, you must compile them into an intermediate ('object') format using-cflag: g++ -c Main.cpp g++ -c Security.cpp This will give you two object files. ...

一个错误是Set函数不能生命为const,因为你里边改变了成员变量的值 还有可能是工程没有关联好,重新建个工程
main.o: In function `main': main.cpp:(.text+0x2c): undefined reference to `Building::Building()' main.cpp:(.text+0x4a): undefined reference to `Student::Student()' main.cpp:(.text+0x59): undefined reference to `Instructor::Instructor()' main.o: In function `Person::Person()': ...
main.o: In function `main': main.c:(.text+0x7): undefined reference to `test' collect2: ld returned 1 exit status 这就是最典型的undefined reference错误,因为在链接时发现找不到某个函数的实现文件,本例中test.o文件中包含了test()函数的实现,所以如果按下面这种方式链接就没事了。
/tmp/ccJjiCoS.o: In function `main': main.cpp:(.text+0x7): undefined reference to `test()' collect2: ld returned 1 exit status 原因就是main.cpp为c++代码,调用了c语言库的函数,因此链接的时候找不到,解决方法:即在main.cpp中,把与c语言库test.a相关的头文件包括加入一个extern "C"的声明就...

undefined reference to “functionA” 在既有的一个c库基础上(c源代码),开个jni接口给Android App使用,竟然折腾了两个小时,郁闷死我了。不过总算搞定了,呵呵。 有个顽固的错误,搞得我不知所措,最后发现竟然是因为我的jni代码后缀cpp,而c库中分开放接口的头文件没有加可被c++使用的申明,导致出现“undefined ...
