iostream and msvcrt?

[Scott Snell]

Hi All,

Thanks to everyone who has helped me with winelib, so far most things are
going really well!  However here is an issue I cant solve - iostream and
msvcrt.  Here is an example file:

// test.cpp module
#include <process.h>
#include <iostream>

int test()
{
        return 1;
}


If I compile it using:

wineg++ -c  -mno-cygwin -I/usr/local/include/wine/msvcrt -o test.o test.cpp

or 

wineg++ -c -I/usr/local/include/wine/msvcrt -o test.o test.cpp

I get a multitude of errors such as:

In file included from /usr/include/c++/3.3.2/iosfwd:46,
                 from /usr/include/c++/3.3.2/ios:44,
                 from /usr/include/c++/3.3.2/ostream:45,
                 from /usr/include/c++/3.3.2/iostream:45,
                 from test.cpp:2:

                 from /usr/include/c++/3.3.2/iosfwd:49,
                 from /usr/include/c++/3.3.2/ios:44,
                 from /usr/include/c++/3.3.2/ostream:45,
                 from /usr/include/c++/3.3.2/iostream:45,
                 from test.cpp:2:
/usr/include/c++/3.3.2/cstdio:167: error: `snprintf' not declared
/usr/include/c++/3.3.2/cstdio:168: error: `vfscanf' not declared
/usr/include/c++/3.3.2/cstdio:169: error: `vscanf' not declared
/usr/include/c++/3.3.2/cstdio:171: error: `vsscanf' not declared


So whats my newbie mistake?

thanks,

Scott.

Using gcc's c++ libraries will not work with msvcrt. If it will compile 
(which it doesn't) it will not load. (Some circular linking)
Your best bet is STLPort. Check it out. What I have done is a special 
makefiles set with special config.h that compiles and links STLPort over 
msvcrt. I have written to STLPort if they want my changes as support for 
another platform but I never got a response from them. Do you need me to 
dig out the old HD and pack you an STLPort compiled over msvcrt?
You might need to make some changes because it is from before winegcc 
times,. Going strait for gcc. and maybe some wine stuff changed since than.

Why are you trying to use G++ with the MSVCRT (Microsoft Visual C++ 
runtime) ? That can surely never work: even if the headers were 
compatible, the ABI used is not.

He meant in a winelib when a winelib links against msvcrt (-nocygwin on 
the winegcc command line). Only the C symbols and  a few C++ (new & 
delete) are exported from wine's msvcrt.spec so only these get linked. 
The rest of the C++ symbols are looked for else where. His current 
problem, though, is Header compatibility.
When you don't use "-nocygwin" than lots of Windows originating code 
(like MFC) does not compile.
