This building problem seems to be caused by a MinGW bug:


http://sourceforge.net/p/mingw/bugs/2024/


So, one solution for the time being is to edit io.h of the MinGW distribution. Replace (line 301 and 302):

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

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

i.e. replace all occurences of�off64_t�with�_off64_t

Then I found this:

I don't know where to change the g++ thing with CMake. Anyone knowing?
