I have to use wide strings in my application for MorphOS (and another OSs). Unfortunately when I compile a source with wprintf function I get:

"undefined reference to `wprintf'"

I use wchar_t, std::wstring with no problems.
Can I use wprintf under MorphOS? How?

I use the last version of MorphOS SDK and GCC 4.4.5 under MorphOS 3.5 (PowerBookG4)

Stupid question, but you have included <string> haven't you?

The new SDK 3.5 is here btw.

It isn't stupid question. :) However answer is: yes, I was trying to include: string, wchar, stdio, stdlib. MOS SDK includes contain wprintf so it should be available.

I will need another functions for wide strings/chars. The wprintf is only one simple example.

BTW - wchar_t and std::wstring work well. :)

Thank you for the info! I will update it today. I like to be updated. :)

The wide-char support in the compiler is very limited, sorry for that. Also, how would you display the output of wprintf if all the MorphOS GUI components do not handle wide-chars? In the end you will need to convert everything to the system code page.

I create game for MorphOS in my small engine where all GUI elements are drawn using OpenGL. I use myown font (3D) system. So wide-strings limitations of MOS GUI aren't problem for me. Currently I am adding support for Unicode and I would like to use wide-strings. The game is compiled also for: iOS, OSX, Windows (and others OSs in future). So I prefer multiplatform techniques.

Function wprintf isn't very important for me. If other functions for wide-strings work (e.g. reading strings from text file), I will be happy enough. :)

Now I know that wide-string support is limited so I will test other functions.

Thank you for help.

I have just tested some functions for wchar/std::wstring. You are right - support of wide chars in MorphOS is very limited. So I won't use standard wide-chars. I have to implement my own simple class for utf-16 strings.
