tenplate class error

[Suneeel]

Hi all,
I'm new at templates.
I've written this code and am compiling it with gcc 4.1.0 on RedHat
Linux 9.

/////////temptest.h//////////////
template <class T>
class tempclass
{
public:
tempclass();
void fun();
}
////////tempclass.cpp////////////////
#include "temptest.cpp"

template <class T>
temptest<T>::temptest()
{
}

template <class T>
void temptest<T>::fun()
{
}
I get the following errors

temptest.h:5: error: ISO C++ forbids declaration of 'tempclass'
with no type
temptest.cpp:4: error: expected constructor, destructor, or type
conversion before '<' token
temptest.cpp:10: error: expected initializer before '<' token

could someone please explain to me what the problem is...

/////////temptest.h//////////////
template <class T>
class tempclass
{
public:
tempclass();
void fun();
}
Missing semicolon.

////////tempclass.cpp////////////////
#include "temptest.cpp"

template <class T>
temptest<T>::temptest()
{
}
Not the same as the previously declared classname.

template <class T>
void temptest<T>::fun()
{
}

Not the same as the previously declared classname.
Note that to use this you have to either place the client code in
[tempclass.cpp] or #include that file, because the definitions must be
available to the compiler when compiling the client code.

The filename [tempclass.cpp] is then misleading; by common conventions
it indicates separate compilation, and there's no such thing for
templates unless you're using 'export' which current compilers simply do
not support (except Comeau, and a secret switch for the Intel compiler).

I suggest using the filename [tempclass.hpp].

Hi,

Try adding a `;' at the end of class declarations/definitions:
class X
{
/* ... */
}; <--
