I am trying to write the following: #include #include <_String.h> int main() { String a; String b; String c; a="Hello World"; b=", Goodbye cruel World"; c=a+b; cout << c << endl; return 0; } Unfortunately I always get a bombardment of errors like: C:\mark\code>gxx -Wall -o test.exe test.cpp -lgpp c:/djgpp/tmp\cccygxwf(.text+0x1b):strtest.cpp: undefined reference to `String::String(void)' c:/djgpp/tmp\cccygxwf(.text+0x29):strtest.cpp: undefined reference to `String::~String(void)' c:/djgpp/tmp\cccygxwf(.text+0x53):strtest.cpp: undefined reference to `String::~String(void)' . . . Any help would be gratefully recieved. Cheers, Mark
