La compilazione statica di Qt 5 fallisce sotto mingw con riferimento a off64_t

Question

Ho provato a fare qt statico e ho avuto un errore durante il mingw-make. Questo è un testo di errore.

static\qhttpnetworkreply.o access\qhttpnetworkreply.cpp

Io uso Windows 8.1. Seguo i passaggi da una sola istruzione.

è un bug in MinGW, quando uno di -ansi, -std = C++ 11, -std = C++ 03 e -std = C++ 98 vengono utilizzati. nel file {MinGW dir} /include/io.h sostituire

__CRT_INLINE off64_t lseek64 (int, off64_t, int); 
__CRT_INLINE off64_t lseek64 (int fd, off64_t offset, int whence) { 

con

__CRT_INLINE _off64_t lseek64 (int, _off64_t, int); 
__CRT_INLINE _off64_t lseek64 (int fd, _off64_t offset, int whence) {
