Compiling c++ files :(

Hi,
Could some body help me solve this compilation problem??
ive' got test.h test.cpp and main.cpp and i need to compile them..
when i type g++ test.cpp main.cpp it says undefined reference ...
following are the files.. could some body tell me how to compile them..!!
//test.h

Code:

#ifndef __TEST_H__

#define __TEST_H__



template <class TYPE>

class Test

{

    TYPE tmp;

    public:

        Test( TYPE d );

        ~Test( );

};

#endif //__TEST_H__

//test.cpp

Code:

#include "test.h"



template <class TYPE>

Test<TYPE>::Test( TYPE d )

{

    tmp = d;

}



template <class TYPE>

Test<TYPE>::~Test( )

{



}

//main.cpp

Code:

#include "test.h"



int main( )

{

    Test<int> tmp(10);

}

Could somebody plz write a make file for compiling this file?
i use g++ (GCC) 3.3.3 20040412 (Red Hat Linux 3.3.3-7)

It _would_ be g++ test.cpp main.cpp, but your code doesnt compile. Try again.

g++ test.cpp main.cpp

/tmp/ccBOhDTz.o(.text+0x1a): In function `main':
: undefined reference to `Test<int>::Test[in-charge](int)'
/tmp/ccBOhDTz.o(.text+0x29): In function `main':
: undefined reference to `Test<int>::~Test [in-charge]()'
collect2: ld returned 1 exit status

This is the output when i compile those files..

The full implementation of a template class must be in that template class's header. The ANSI/ISO standards for C++ allow for a way to put the implementation in a separate compilation unit using the export keyword (I think that's right, anyway...), but I don't think that there are currently any compilers that actually support this.

Edit: Just thought I'd elaborate a bit more. I am not a compiler writer, so the following might not be completely accurate.

I believe that the reason for needing the full implementation in the header is that the compiler will typically only compile a template class when a "specialization" of that class is instantiated. The compiler will also only compile the parts of the template class that actually get used. So, when the compiler is compiling a single .cpp file that instantiates a specialization of a template class, it needs to have the full definition of that template class to correctly compile it.

Edit2:
In searching Google a bit to make sure I didn't make any claims that were too drastically wrong, I found a link that explains exporting templates a bit here.

Wow!!! That was really nice.. thanks man...
i was breaking my head on this.. ofcourse couple
of my friends too :)
Well nice reading that link too :)

Thanks a lot deiussum. I was struggling with this problem all evening. Finally I am relieved!!! And the link you gave was interesting.

Herb Sutter's Article on Export (New Location)

Well the thread helped a lot .... believe me ... For people like us who are trying out C++ after working for a long time in Java, small blocks held u up for days :(.

I tried to search for the article but did not get it (the above link is dead). The new location for the same is http://www.ddj.com/cpp/184401563. Thought it would help poor souls like me banging their heads.
