2012/6/12 Yaakov (Cygwin/X):Currently I get:
/usr/i686-w64-mingw32/sys-root/mingw/lib/libmsvcrt.a(daqubs01139.o):(.text+0x0): multiple definition of `_swprintf' io_stream_file.o:/usr/i686-w64-mingw32/sys-root/mingw/include/wchar.h:547: first defined here
How about this change instead to both headers:
--- crt/wchar.h (revision 5094) +++ crt/wchar.h (working copy) @@ -450,10 +450,10 @@ int __cdecl __mingw_vsnwprintf (wchar_t * __restrict__ , size_t, const wchar_t * __restrict__ , va_list);
#undef __mingw_ovr -#ifdef __cplusplus -#define __mingw_ovr inline __cdecl -#elif defined (__GNUC__) +#if defined (__GNUC__) #define __mingw_ovr static __attribute__ ((__unused__)) __inline__ __cdecl +#elif defined(__cplusplus) +#define __mingw_ovr inline __cdecl #else #define __mingw_ovr static __cdecl #endif
Hmm, that's looking wrong to me, too. __GNUC__ gets defined also for c++, So issue might be more related to inline being not inlined. Could you provide me a small sample to reproduce this issue?

int test_printf(const std::string &str) { return printf (str.c_str()); }
