Here is the root cause. gettext use C linkage at gettext-runtime/libasprintf/vasprintf.h:
#ifdef __cplusplus extern "C" { #endif /* Write formatted output to a string dynamically allocated with malloc(). If the memory allocation succeeds, store the address of the string in *RESULT and return the number of resulting bytes, excluding the trailing NUL. Upon memory allocation error, or some other error, return -1. */ extern int asprintf (char **result, const char *format, ...) __attribute__ ((__format__ (__printf__, 2, 3))); extern int vasprintf (char **result, const char *format, va_list args) __attribute__ ((__format__ (__printf__, 2, 0))); #ifdef __cplusplus } #endif On stdio.h, mingw-w64 use C++ linkage: /* There seems to be a bug about builtins and static overrides of them in g++. So we need to do here some trickery. */ #ifdef __cplusplus extern "C++" { #endif ... #ifdef _GNU_SOURCE __mingw_ovr __attribute__ ((__format__ (gnu_printf, 2, 3))) __attribute__((nonnull (1,2))) int asprintf(char **__ret, const char *__format, ...) { register int __retval; __builtin_va_list __local_argv; __builtin_va_start( __local_argv, __format ); __retval = __mingw_vasprintf( __ret, __format, __local_argv ); __builtin_va_end( __local_argv ); return __retval; } __mingw_ovr __attribute__ ((__format__ (gnu_printf, 2, 0))) __attribute__((nonnull (1,2))) int vasprintf(char **__ret, const char *__format, __builtin_va_list __local_argv) { return __mingw_vasprintf( __ret, __format, __local_argv ); } #endif /* _GNU_SOURCE */ ... I think mingw-w64 should not use C++ linkage for these C functions when use C++ compiler.
