I am new to freertos and I am trying to test the Network and FAT demo. I am trying to compile it with Microsoft Visual Studio 2015. When I try to compile It I get the following errors on the stdio.h file:
Warning C4005 'vsnprintf': Macro redefinition
Error C1189 #error: Macro definition of vsnprintf conflicts with Standard Library function declaration RTOSDemo
On StackOverflow I have found a reference to a similar problem but solution does not work for me:
http://stackoverflow.com/questions/27754492/vs-2015-compiling-cocos2d-x-3-3-error-fatal-error-c1189-error-macro-definiti
What I am missing?
Thanks in advance.
#error Macro definition of vsnprintf conflicts with Standard Library function declarationPosted by edwards3 on March 9, 2016 Looks like a compiler version difference issue. Did you grep for #defines like the example in your link?
#error Macro definition of vsnprintf conflicts with Standard Library function declarationPosted by jordiblasi on March 9, 2016 I commented all the #defines related to vsnprintf but I got errors relating to _vsnprintf function.
Error C2084 la función 'int vsnprintf(char *const ,const sizet,const char *const ,va_list)' ya tiene un cuerpo
#error Macro definition of vsnprintf conflicts with Standard Library function declarationPosted by heinbali01 on March 9, 2016 Yes I had the same when moving from VS2010 to VS2015. In earlier versions, snprintf() was considered unsafe and and alternative (_snprintf ) had to be used.
This could be used as well:
~~~~
#if MSCVER < 1500
#define snprintf _snprintf
#define vsnprintf _vsnprintf
#define strdup _strdup
#endif
~~~~
Adeu/adios.
#error Macro definition of vsnprintf conflicts with Standard Library function declarationPosted by oscarlpez on August 4, 2016 Hi,
Has finally anybody solve successfully this issue?
I am not sure in which file need to be included the previous solution. In stdio.h file?
Thanks for sharing.

#error Macro definition of vsnprintf conflicts with Standard Library function declarationPosted by rtel on August 4, 2016 It is not clear to me why you think the problem has not been solved, or
why it is a problem at all - it just depends on which version of Visual
Studio you are using.
Did you try Hein's solution?
#error Macro definition of vsnprintf conflicts with Standard Library function declarationPosted by oscarlpez on August 5, 2016 I was trying Hein's solution, but I don´t know which file mofify, or in which file should be included the changes. I am using VS2015.
Thanks again
Oscar
#error Macro definition of vsnprintf conflicts with Standard Library function declarationPosted by rtel on August 5, 2016 Did you try grep'ing the directory structure for where the function
names snprintf and _snprintf already occur in a macro? From the thread
it sound like you just need to remove or update the macro mapping.
