What do these 2 Errors mean ?

[posty68]

Hi
What does this Error message mean ?

FSInsertLink.obj : error LNK2001: unresolved external symbol "public: virtual __thiscall RfcCommand::~RfcCommand(void)" (??1RfcCommand@@UAE@XZ)
FSInsertLink.obj : error LNK2001: unresolved external symbol "public: __thiscall RfcCommand::RfcCommand(void)" (??0RfcCommand@@QAE@XZ)

Thanks

The problem i am getting
is that im including a file which declares a class RfcCommand
and now im trying to instantiate an object of that class

ie - RfcCommand cmd;

but im getting the Errors above ?

any help would be appreciated!

[Andreas Masur]

LNK2001...

[Andreas Masur]

In other words...you need to provide the implementation of the class as well...

[posty68]

So i can't just #include "TheFile.h"
and then create an object of the class defined .

i have to #include "TheFile.h"

what do u mean by an implementation ?
surely i can use the one in the .h file ?

[posty68]

Hi
Ive now addedd the MyFile.h and MyFile.cpp which include the class required
which gets rid of the Error message

Thanks

But now im getting this Error message
fatal error C1010: unexpected end of file while looking for precompiled header directive

can you explain this one ?

Well...yes and no...if the implementation of member functions are being made within the header file, then the header file would be sufficient...

// header
class CFoo
{
  void Func();
};

With this header you declare a class named 'CFoo' which contains a function named 'Func()'. If you want to use the function in your code, the compiler needs to know where to find the implementation of this function...in other words, the .cpp file

// .ccp
void CFoo::Func()
{
  // Do something
}

fatal error C1010: unexpected end of file while looking for precompiled header directive

I actually do not have much time at the moment...thus, I could not look at your code, however the following might already help...

• C1010

[kirants]

Your project settings option might have specified that the file ( in which you are getting this precompiled header ) is to use a precompiled header ( in most cases it would be stdafx.h , or in general it is a file you specify that with which to create precompiled header ).

So, if the compiler sees that there is no #include <stadfx.h> ( for example ), it will complain.

Merely adding the include will resolve the problem.

More info:
1. Go to project settings, select the C/C++ tab, select category as precompil... headers.
2. Now, when the project is selected, you might possibly see Use precom... option selected.
3. Now, expand the project tree on the LHS and select stdafx.cpp if you have one. In this case , you will probably see that the option selected is Create precompiled header using stdafx.h

Precompiled headers are used to speed up compilation. Normally, the commonly used includes are included in the stdafx.h. So, compiler will create a precompiled header file ( .pch ) as a timesaving step.

[posty68]

Yes i found that it was the stdafx include problem
which i have solved by changing the settings

thanks one and all
now to look at the other issues ....


ohhh how debugging never seems to stop
