tcc: error: undefined symbol '_ftelli64'

[qaisyTako]

I've been having trouble to compile a few coding from the raylib 'example' folder.
It always show this error:

tcc: error: undefined symbol '_ftelli64'

I even compile in it the original folder of raylib when we first installing the raylib.

One of the program I try is the models_cubicmap.c

msvcrt.dll doesn't export '_ftelli64' and tcc doesn't implement it

• the reason this isn't a problem on mingw64-gcc is they implement it statically using functions that actually are exported by msvcrt.dll

'_ftelli64' is used by 'cgltf' which is included in 'rmodels.c'

you can replace the include with something like this:

#if defined(_WIN32) && defined(__TINYC__)
  #ifdef __int64
    #undef __int64
  #endif
  #define __int64 long
  #define _ftelli64 ftell
#endif

#define CGLTF_IMPLEMENTATION
#include "../1-cgltf/cgltf.h"

#if defined(_WIN32) && defined(__TINYC__)
  #undef __int64
  #define __int64 long long
  #undef _ftelli64
#endif

^ in which case your file size will be limited to a 32-bit integer, but it compiles

You can use _fileno and _telli64, with tcc.

_fileno for getting a file descriptor (an int) from your FILE* stream, and then use that descriptor with _telli64 to get a 64 bit position.

Something like this:

#if defined(_WIN32) && defined(__TINYC__)
  #define _ftelli64(stream) (_telli64(_fileno(stream)))
#endif

mingw-w64 headers do expose these functions, I managed to get it working by copying headers from a mingw-w64 gcc installation over to tcc. Somewhat of a hack but I did not see a better way.
