I use the last version of Djgpp. C programs works OK. I am testing the C++ library. To test the C++ I wrote : #include <iostream.h> int main() { int a = 100, b=200; cout << "Hello " << a + b << endl; return 0; } It works OK. To test the String C++ class I wrote: #include <iostream> #include <_String.h> int main() { String str = "Hello "; String str1 = "boys!"; cout << str + str1 << endl; return 0; } Compiling is OK. Linking aborts. I get : undefined reference to "String:: ...." To test the C++ Integer class I wrote : #include <Integer.h> int main() { Integer a = 100; Integer b = 200; cout << a + b << endl; return 0; } Compiling is OK. linking aborts. I get undefined reference to "Integer::..." What is the problem ? TIA. Gallicus.
