Good afternoon,

I have problem with linking class String (from _string.h), while other classes from libgpp.a links ok. I'm using gcc 2.8.0 with lgpp 2.8.0.

Here is my sample program (test.cpp):

#include <_String.h>
#include <iostream.h>
main() {
       String s("blabla");
       String s1;
       s1 = "huhu";
       cout << s << "\\n" << s1 << "\\n";
       cout << s.at(2,6) << "\\n";
}

and here are linker messages (after "gcc -o test.exe -lgpp -lstdcxx test.o"):

Creating: test.exe
Error: test.o: In function `main':
test.cpp(1) Error: undefined reference to `String::String(char const *)'
test.cpp:4: undefined reference to `String::operator=(char const *)'
test.cpp:6: undefined reference to `cout'

test.cpp(.text+0x14b): undefined reference to `String::~String(void)'
test.cpp(.text+0x16b): undefined reference to `String::~String(void)'

Thank you very much for your help.
