STLPort, Visual Studio 6, and streams

I cannot figure out why this is happening ... I installed STLPort, uncommented the "# define _STLP_NO_OWN_IOSTREAMS 1" in stl_user_config.h, and no matter what file I include the symbol std::basic_ostream<T> cannot be found. Any ideas what I am doing wrong?

Did you search to see what defining that would do????
Maybe defining that undefines several other things.

Yeah, I have tried all sorts of sh1t like that ... no luck yet.

Well it obviously undefines (or redefines) something

Are you using an IDE, and if so what?

Yes, Visual Studio 6

Yeah, shoulda re-read the topic... I don't know if 6 has this feature, but right click on the call that's coming up undefined now and do "show definition" or something to see what defines are around it.

Remove all reference's to VC++'s STL from your directory options, it looks like VC++'s std:: namespace is conflicting with STLPort's std:: namespace (which is really called stlport::, but is redefined by macros).

That problem is solved by putting the STLPort search path first in Tools->Options->Directories->Include Files.

I think I found a solution though ... testing it now. All documentation I have seen says to define the tag _STLP_NO_OWN_IOSTREAMS in stlport/stl_user_config.h in order to use the local streams as opposed to the SGI streams. That clearly doesn't work. I was examining stlport/stl/_site_config.h and found an ifdef that defines _STLP_NO_OWN_IOSTREAMS if _STLP_NO_IOSTREAMS is defined. So, from the project settings I defined _STLP_NO_IOSTREAMS and VOILA! Success so far ...

Ah, the joys of preprocessor macros.

Thank God for C#.

Except C# is sort of semi-interpreted vaguely like Java, isn't it?

So near, yet so far... :]

Not to the extent of Java. The CLR is not a complete VM like the JVM is. Close, but not entirely the same.

I say it's a matter of time before someone writes an operating system which implements .NET natively.

I believe the next windows OS was supposed to be, but MS decided the language was still too young.

I <3 C++.
