I have been searching for a solution to get rid of missing -D__STDC_CONSTANT_MACROS message in Visual studio express 2013 to no avail. I already have included stdint.h and inttypes. Within the common.h header file here http://www.ffmpeg.org/doxygen/trunk/common_8h_source.html there on line 29 there is a following part 

#if defined(__cplusplus) && !defined(__STDC_CONSTANT_MACROS) && !defined(UINT64_C)
#error missing -D__STDC_CONSTANT_MACROS / #define __STDC_CONSTANT_MACROS
#endif

However, it appears that __STDC_CONSTANT_MACROS is defined in the stdint.h. But I still get the error. the source I am trying to compile is here: http://ffmpeg.org/doxygen/trunk/decoding__encoding_8c-source.html

Thanks,

jax

  • @Mgetz; That solution is for Ubuntu not Visual Studio. – jax Dec 12 '13 at 16:57

    @HansPassant: That Solution explains what `__STDC_CONSTANT_MACROS`is all about and to define `__STDC_CONSTANT_MACROS` before stint.h but it doesn't say How to define it. Also, as I said in my question it appears that it is defined in stdint.h. – jax Dec 12 '13 at 17:00

-D__STDC_CONSTANT_MACROS error was solved by: project properties -------> configuration properties -------> c/c++ ----->command line

at additional option enter: -D__STDC_CONSTANT_MACROS

that is what worked for me hope it will help someone else
