error: '::swprintf' has not been declared

Hi. I was trying to compile an example program I found on (and copied straight off) Boost's getting started page, using MinGW's g++ and MSYS' make, when I got the following compiling result:

Code:

"error: '::swprintf' has not been declared". What can cause this problem? Has anyone had the same or a similar problem before? Thanks in advance!

I had the same problem too. Probably this happens because your compiler doesn't support Unicode, therefore these function that use wchar_t aren't there! ( i don't know )

Then how should it be done? Maybe the example code calls some function that is not platform independent? At least the function seems to have been removed, moved, or renamed, when g++ was ported to Windows and MinGW.

So my next question is then: if this problem can not be solved, while using the same code, is there some other code that does work which I can use as a minimal boost example, so I can see that boost has been configured in the right way on my computer? The reason I tried to compile the example code from the first time was to see if I had set Boost up correctly, before I started to use it.

Sipher, were you possibly also trying to get boost working with mingw/g++ on windows?

The example code works fine with Visual Studio 2008, as expected. I think the problem in this case is that Boost and MinGW are not guaranteed too work together; see the beginning of Boost's Getting Started on Windows guide. I'm changing to Visual Studio.
