Yes, it's a mystery. I would assume that your mingw-w64 is older than mine. They may have since implemented the integer to string conversion routines the compile error is complaining about recently.
The bug is caused by symbols `_ui64toa_s` and `_itoa_s` being used but not declared. Do you need platform-specific things for accomplishing your task? Are there no C++-standard ways of converting integers to string that would work for you?
The compiler errors you sent me said that they weren't declared in scope. Not undefined reference. Likely your mingw-w64 headers are incomplete. Remember that file is C code, not C++ code, and it's Windows-only, so the choice of number to string function is more limited. Using itoa() directly is frowned upon by MSVC with warnings, so I used itoa_s() to shut it up. Fixing your compile error would be extremely trivial, we just need a way of selecting itoa() vs itoa_s().
If you can figure out a way of detecting mingw-w64 version, I can use the non-_s editions of those conversion functions. That would get you up and running on your version of mingw.
Ok, I'll look for it. You mean how to tell a 64 versus non-64 version of minGW, right?
I'd even accept #ifdef __MINGW_W64__ or whatever its macro is. Niall -- ned Productions Limited Consulting http://www.nedproductions.biz/ http://ie.linkedin.com/in/nialldouglas/
