軟體是dev_c++ 小弟開成三個檔分別是 // lab1-1.h namespace Complex{ typedef struct{ double real; double image; }Cplex; const double pi = 3.1416; void showComplex(const Cplex &m); } // lab1-1.cpp #include <iostream> #include "lab1-1.h" namespace Complex{ void showComplex(const Cplex &m) { std::cout << m.real; if (m.image < 0) std::cout << m.image << "i" << std::endl; else std::cout << "+" << m.image << "i" << std::endl; } } // lab1-1-main.cpp #include <iostream> #include "lab1-1.h" using namespace Complex; int main() { Cplex n; n.real = 1 * pi; n.image = -0.5; showComplex(n); return 0; } 會出現 C:\Users\T12034~1\AppData\Local\Temp\cccfgPBD.o lab1-1-main.cpp:(.text+0x31): undefined reference to `Complex::showComplex(Complex::Cplex const&)' C:\document\collect2.exe [Error] ld returned 1 exit status 不知道該怎麼修改救命啊!! -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 117.56.244.182 ※ 文章網址: https://www.ptt.cc/bbs/C_and_CPP/M.1438070164.A.37E.html
