【问题描述】：

我尝试制作静态 qt，但在 mingw-make 期间出错。这是错误文本。

我使用的是 Windows 8.1。我按照一个说明中的步骤进行操作。

【参考方案1】：

这是 MinGW 中的一些错误，当使用 -ansi、-std=c++11、-std=c++03 和 -std=c++98 之一时。 在文件 MinGW dir/include/io.h 中替换

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

与

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