I'm finally getting around to teaching myself C++ using DM.
The book I'm using is Accelerated C++.
I only started today, but the already the simple examples (said to be ANSI)
are not compiling.

For example:

    // a small C++ program
    #include <iostream>

    int main()
    {
         std::cout << "Hello, world!" << std::endl;
         return 0;
    }

This fails because it requires the #include to include the .h extension.
Changing this and recompiling gives the following messages:

tip.cpp:
        std::cout << "Hello, world!" << std::endl;
                ^
tip.cpp(6) : Error: 'cout' is not a member of namespace 'std'
        std::cout << "Hello, world!" << std::endl;
                                                 ^
tip.cpp(6) : Warning 6: value of expression is not used
tip.cpp(10) : Error: need at least one external def
--- errorlevel 1


OK, I know it works when std:: is removed, but why ??

    using namespace std;

It is not yet implemented;
DM it is not yet fully ANSI compliant.

So the -A switch for strict ANSI is of little use ?

would say it's just not fully implemented as yet.

// a small C++ program
#include <iostream.h> // not the added extension .h
using namespace std;   // as stated by the ANSI standard

int main()
{
     cout << "Hello, world!" << endl;
     return 0;
}

This is because the way the SGI iostream library is set up, it is not fully
implemented yet and is still experimental. There are indeed two versions of
the iostreams library, one which is iostream.h, which simply defines
everything in the global namespace and iostream, which defines everything in
the std namespace. The SGI iostreams implementation does not yet include the
iostream header, which is why you get an error for your program. What you'd
want to do is use STLport instead, you can get it off the DM CD or download
the latest version from the DM site. Follow the installation instructions
and make sure you place the stlport path before the SGI stl path in the
SC.INI file. Try your initial program again and you should find that it
compiles and works beautifully.

I've updated my CD releases until the latest one.
I've downloaded and installed the STLport files.
When I try to make the library I get the following

 make -fdm.mak clean all



Any ideas why this is happening ??

To build the STLport libraries and dll's:

        cd \dm\stlport\src
        smake -f dm.mak

which will build them into \dm\stlport\lib. To install them:

        xcopy \dm\stlport\lib\*.lib \dm\lib
        xcopy \dm\stlport\lib\*.dll \dm\bin

Please check out \dm\stlport\readme.txt for more details.

Cheers Walter.
I found the readme.txt at the same time I got your reply.

<iostream> is in \dm\stlport\stlport. Try using the -I\dm\stlport\stlport
switch.
