Errors when compiling

I get errors when compiling 1st sample on Mingw32.

I guess they appear because mingw32 hasn't got wide characters and wide strings. Any way to fix this?

Download the latest version: 0.9.2 prerelease . I have added a macro TTMATH_DONT_USE_WCHAR, define this macro when compiling.

Btw mingw is a MS Windows port of GCC compiler, your version is probably 3.4.5 and is a little outdated. The current version of GCC is 4.4.3. But unfortunately those binaries provided by www.mingw.org don't support wide characters too. I have checked version 4.4.0 and wchar_t was in ::tr1 there.

I am using mingw compiled from sources by myself and wide characters work well.
$ gcc -v
