need help porting old code to Intel C++

hello

I have an old program that I'm trying to port from MS Visual C++ v6.0 to Intel C++ v11.1.048

And being a newbie I'm having a few problems.

Specifically - the old code references a fstream.h - which is not found. It appears that this may be a microsoft thing, as I can't find it with the Intel copmpiler. Presumably there is an equivalent?


Also I'm getting a large number of "error: ConstructElements is not a template" and "error: DestructElements is not a template" messages when comopiling the .h files

I would include an example of the code - but my posts just crash if I do - I'll try attaching an instead...

What is the best way around these issues?

Any help in getting the code to compile would be gratefully recieved.

Thankx

Jim

Intel C++ should inherit from the base C++ installation (the VC++ 7.1, 8, or 9 you had to install prior to ICL). As pre-dated standardization from fstream.h to fstream, you probably need to make the change and see how far it takes you.


.h (header) files can't be compiled, unless to .pch (pre-compiled header). If you have trouble, someone may be able to help if you will attach a complete example, including the C++ source code.

As far as the header is concerned, the name of the header in the C++standard is fstream not fstream.h.

So you need to change fstream.h to fstream and also put :

using namespace std;

After the#includesince all the names are going to be in namespace std.

The errors about ConstructElements and DestructElements occur because you have specializations declared in the IMAGINFO.H header, i.e.:

template void AFXAPI ConstructElements (CImageInfo** pElements,
int nCount);

The template syntax says I am declaring a specialization for this template function. In order for that to be valid you need to have declared a non-specialized ConstructElements template function previously.

If you preprocess the whole source file (i.e. use -P or -E) and attach that may be we can tell you more. Is there a declaration of ConstructElements in some other header that is included before this header?

Thankx

Found I also needed to include

to find some of the classes declared differently
