unknow type name 'off64_t'

或者 

错误"error: 'off64_t' does not name a type"

 

MinGW的bug,使用-std=c++11, 有可能出现, 修改{MinGW dir}/include/io.h文件,

使用:

[cpp] view plaincopy

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

代替:

[cpp] view plaincopy

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

即可.
