I'm attempting to modify a MotorWare example project (project 01 for the boostxl_drv8305 and F28027x C2000 chip) to output sinusoidal PWM signals.
In doing so, I've used the IQMath library and I believe that I have successfully included the library file (already included in example project) as well as the correct header file to access the IQMath lib functions.
I've had a look at the IQMathLib.h header I am including and it contains a definition for the _IQSin() I am trying to use, but I get the following build error:

As can be seen, the IQmath.lib file for this CPU is in the linker's path.
The following shows the warning during compilation of my code:

I get an error about an implicit declaration, despite the declaration being present (or at least redefined to _IQ30SIN() and then that is defined extern) in the IQMath header in C:/ti/motorware/motorware_1_01_00_15/sw/modules/iqmath/src/32b/ (I use #include "sw/modules/iqmath/src/32b/IQmathLib.h" for good measure).
Here's the top of my C file:
// the includes
// system includes
#include <math.h>
// modules
#include "sw/modules/math/src/32b/math.h"
#include "sw/modules/iqmath/src/32b/IQmathLib.h"
#include "sw/modules/memCopy/src/memCopy.h"
// drivers
// platforms
#include "main.h"
What's going on here? I'm certain I'm doing something stupid, so I've attached a screenshot of my work environment in CCS as well as a zip of the project.
proj_lab01.zip
