Greetings all,

I am having a spot of trouble with the _String.h file. The C++ compiler
cannot find it. I am trying to compile the following:

#include <iostream.h>
#include <_String.h>

int main() {
	String a;
	
	a="Hello World";
	cout << a << endl;

	return 0;
}

and I get:

C:\mark\code>gxx -Wall -o strtest.exe strtest.cpp
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)'

I am using Windows NT, Djgpp was installed using an unzip utility
that did not support long file names and all environment variables we
set correctly, I've tryed compiling the program with LFN=y and LFN=n,
I've tryed #including <strstring.h> instead of #include <_String.h>, the
header file _String.h does exist in the C:\Djgpp\lang\cxx directory, and
I've read section 8.2 of FAQs.

Is there anything else I can try or do or missed.

Any solutions would be gratefully received.

Cheers,
Mark
