Im using an Arduino 101 - the Intel Curie model. I'm just getting the built in General Vision 128 node hardware neural network working.

I build the project using the 101 libs and tool chain.

I however get his in my errors view

Severity    Code    Description    Project    File    Line    Suppression State

Error (active)        #error directive: "Unable to determine type definition of int32_t"    helpme    1\arc-elf32\include\sys\_intsup.h    89   

What's weird is the fact I click on the first error, and it shows me the definition for the utoa function, and then the first 5 errors vanish the instant the file is opened, there are now only the last 2 errors showing. I'm not sure why they would suddenly disappear, but I assume its to do with my paths to header file includes for the pre-processor ?

When I click on the first file it takes me in VS to

\arduino

stdlib_noniso.h

Which is the correct file for the Arduino 101, as the Arduino15 folder is the Intel 101 libs and headers.
When I do that the first errors vanish and leaves me with 2, when i click on the first of those I get

1\arc-elf32\include\sys\_intsup.h

_intsup.h

come up in the editor, on this line

#if (__INT32_TYPE__ == 4 || __INT32_TYPE__ == 6)
#define _INT32_EQ_LONG
#elif __INT32_TYPE__ == 2
/* Nothing to define because int32_t is safe to print as an int. */
#else
#error "Unable to determine type definition of int32_t"
#endif

So it doesnt know the size of int, whether its 2 or 4 bytes. Obviously the 101 is a 32 bit machine, so its a 4 byte int fot the compiler. So I presume a file that is being pulled in should be pre-prcoessor #define'ing the 32/4 byte int size ?

Anyway, after all this, the file does actually compile, and i can upload it to the 101. So really it;s just a huge red herring. I still spent some time wasted on it though.
