I'm writing some C code, to compile and use as an S function in simulink.
In normal C programming, I can just declare variables to be a certain size, like
int16 x = 5;
uint32 y = 7;
But when I try that in matlab, and compile it with
mex file.c file_wrapper.c
I get an error message:
unknown type name ‘int32’
I've tried `Int32' and `int_32' and neither works.
Is there some library I need to include?
Mex gives me the following warning. Is it related to this?
Warning: You are using gcc version '5.4.0'. The version of gcc is not supported. The version currently supported with MEX is
'4.7.x'.

I found the answer.
This stack overflow post explains.
  • Add tmwtypes.h as a library
  • Use `int32_T` as the type.
