If I comment out the the 3 lines in the StarSystem Constructor that create objects, then it compiles, so I know this has to do with the issue. #include<iostream>#include<vector>#include<string>#include<stdlib.h>#includeusingnamespacestd;classSystemBody{public:SystemBody();intsystembodyindex...

D:/Coding/CG/Assignment0/TestVec/main.cpp:22: undefined reference to `Vector3f::Vector3f(float, float, float)' Actually that is not compile error, it is a linker error. This error is telling you that the linker can't find the implementation of that function. Did you write the code fo...
Then I want to use this library in a C++ project. I wrapped an extern "C" around the include of the header files to eliminate name mangling. However, I got linker errors for the library functions (undefined references). The C++ project adds an "__imp_" to the name of c functions. ...
I have created a class to manage an ADC converter chip. That class is declared in ADS1216.h ADS1216.h 12345678910 class ADS1216_PD { public: // Constructors ADS1216_PD(int cs, int drdy); ADS1216_PD(SPIClass *s, int cs, int drdy); ... void setMux(ADS1216_MUX muxSetting); }...
最近想写个demo验证Qt connect在第五个参数不同的情况下,各自槽函数运行在哪个线程中。为了简便,就没有创建.h和.cpp文件,直接在main函数中写的,结果在运行时就出现了 undefined reference to `vtable for * * * '这种错误。 代码如下: class SendMsg : public QObject ...
undefined reference to `Card::Card(int,int)这种提示表示，card:card()没有定义。有两种情况，一种是没有写代码。另一种是没有链接包含Card::Card函数的库。编译未成功。你有两个主要错误：1 你的静态数组没有实例化就在初始化函数中赋值了。2 提示undefined reference to `Card::Card(int,int)...
