To clarify things: __MINGW32__ and __MINGW64__ : They are both compiler 's built-in macros. __MINGW32__ is valid for both mingw.org and mingw-w64, for both x86 *and* for x64. __MINGW64__ is *only* valid for x64, therefore effectively for mingw-w64, because mingw.org doesn't support x64 (at least not yet.) __MINGW64_VERSION_MAJOR, on the other hand, is *not* a compiler built-in macro. It is a macro defined by the mingw-w64 headers, specifically through _mingw.h. Most, if not all, of the headers already include _mingw.h, so if you want to check for .__MINGW64_VERSION_MAJOR you must do it *after* including some standart headers such as stdio.h or stdlib.h or even windows.h >> I think __USE_MINGW_ANSI_STDIO only applies to the printf family, the >> scanf family has not been ported yet, so you'll need to use %I64u >> instead of %llu. >> > > Hello, thank you all for your replies.

If you truly want to define the things for mingw-w64 *and* before including further headers yet, try something like this at the top of your source: #ifdef __MINGW32__ #include <_mingw.h> #endif #ifdef __MINGW64_VERSION_MAJOR [your stuff here] #endif #include [your actual includes here] Hope these help. -- Ozkan ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
