pointer to a parametrized template

Hello, everybody!

I'm trying to do some programming in VC6, and ran into the following problem. I made a CMatrix<template T> class, that does some simple matrix calculations. Now I defined a (normal) class, in which I wanted to use a couple of these CMatrix'es in the following way:
CMatrix<double> *a;

(in the definition)

and to use a new operator with the parameterisation on these pointers later.

The compiler gives loads of errors :

missing ';' before '<'
'CMatrix' missing storage class or type specifiers
syntax error '<'
unexpected tokens preceding ';'

To me this makes no sense. Is this kind of thing impossible? Can anybody please help me?

Does your template header include the fully defined class? With templates, it is not enough to provide function prototypes - you have to provide their implementation too.



The best things come to those who rate

Yes, the template works in other instances...

Henk

did you include the header file in which it is declared - and use any namespace you needed to use ?

I included the matrix.h file, I'm not sure about the namespaces; the template works in all other things I tried...

Henk

The sure check to see if you are correct that matrix.h is included is to put the following line in matrix.h

#pragma message("Matrix.h is included")



This can go anywhere within the matrix.h file. When you compile your .CPP file, do you see the message "Matrix.h is included" in your compiler output window? If not, this means that you are not including the header, even though you think you are.

I've tried this, and indeed the header file is included after the definition of the class.... Have you any idea how to correct this?

Thank you very much! Henk

Well, everything works now.... It appears to be a problem of the order in which I include the header files, taking the matrix.h to the end of the list solved the errors. I didn't expect this! Oh well, for me there's always a bit of magic involved.

Thank you all for responding! Henk
