 STL iostreams relies on wide character support. There is no wide character
 support in DOS extended programs, because DOS has no wide character support.


There are other platforms described in the STL source e.g. AIX, which have
no wide character support.

#define _NOTHREADS
#define _STLP_NO_NATIVE_WIDE_FUNCTIONS
#include <iostream>
using namespace std;

int main() {
  cout << "Hello World!\n";
}

IDDE output:

sc hello3.cpp -mx -NL -NLx32.lib -5 -a4 -c hello3.obj
link /NOI /DE /PACKF /XN  hello3.LNK
Warning: c:\dm\lib\stlp45dm_static.lib (1): Memory Model Conflict
Error: c:\dm\lib\user32.lib (1231564): Not a Valid Library File
Lines Processed: 16678 Errors: 1 Warnings: 1
Build failed

Is there any way I can find what is contained within hello3.LNK?

Perhaps you can explain why there is a 'memory model conflict'
and why 'user32.lib' is even there for a DOSX application.

Because stlp45dm_static.lib is compiled with the Win32 memory model. Trying
to link this with -mx compiled .obj's will result in the "Memory Model
Conflict" message. Embedded in the library is a directive to load the
default libraries that support Win32, hence the attempt to link in
user32.lib.

If you wish to get this to work, I suggest looking at how to build the STL
libraries (look in \dm\stlport), and try to get a build going for -mx.

The newer STLport 4.6 libraries are also available at 
http://mordred.cs.ucla.edu/STLport_DMC/. With a little tweaking of the 
smake makefile, you could compile it up for DOSX or a different platform 
altogether.

 Thank you both, Walter and Scott


You're welcome. If you do get STL to work with DOSX, please post here some
instructions so that others can stand on your shoulders!

Just found this on c++.stl.port in which you say it can be used for Dos ...

 Would is it be possible with a reasonable ammount of effort
 to compile the iostreams STLport library as a static library for
 a DOS 16 bit platform?
 Any ideas on how much of an effort this would take to do?


I think it is not worth while since it would wind up too large for the 16
bit memory space.


 Even when using a large memory model? Is the iostreams library that large?


 You can try it if you want. I know of no particular reason why it wouldn't
 work, but I have not tried it.
