Erros in Utility Header File

I'm using vc++ Introductory Edition. I also have the commandline version of vc++.net that comes with the .net sdk. The vc++.net compiler compiles c code fine but not the c++ code because it doesn't have the STL i think someone said. So I had an idea. I copied the vc++.net compiler (cl.exe and other dlls) to the vc6 bin directory. I don't have problems compiling c code but I am still having problems with c++ code. A simple c++ program that includes iostream gives me these errors.

Code:

Can any c++ gurus help me with this?

I think that pretty much sums up the problem

VC++ 6 compatibility with the standard was crap compared to vc++.net - its no wonder its barfing on all those header files.

The rule about not copying header files from one compiler to another even applies to different versions of the same compiler.

You've also killed your previous vc++ 6 installation as well.

If you want a decent c++ compiler with STL, then I'd suggest you look at dev-c++

In other words, the old headers from VC++6 are written so that the (bad) VC++6 compiler can compile them.
The new VC++7.1 compiler however cannot because it can only compile code that follows the C++ standard.

Thanks for the replies. Is there an sdk or something that has the stl for vc7? Why ms can't give us the stl? :(

Because you're supposed to BUY the compiler ;)
And because the C++ compiler provided with the .Net SDK is only meant to compile Managed C++ bridges.

You can download STLport, it's a free STL implementation and should work with VC++7.1
