Tool/software:

Hi all,

I have with TMS320F28P650DK9 C2000Ware_5_01_00_00.
I am trying to include the CLAmath.h in the CLA; however, the following line

#define tanf(m) (CLAsin_inline(m)/CLAcos_inline(m))

creates the following compilation error:

>> Compilation failure
source/subdir_rules.mk:16: recipe for target 'source/claTask.obj' failed
"C:/ti/ccs1260/ccs/tools/compiler/ti-cgt-c2000_22.6.1.LTS/include/math.h", line 387: error #18: expected a ")"

Line 387 in math.h is the following line:
_CODE_ACCESS float tanf(float x);

Commenting it out everything works fine.
Any clues?

Hi Matteo,

Are you using the cla_sin library example from C2000ware as your starting point? If not, which example did you use to start with? And just to verify, you are seeing this error when using the example unchanged, correct?

Best Regards,

Delaney

Hi actually the examples seems okay.
I have my code where I tried to follow the guideline to include CLA_MAth libarry (header + .lib).
Would the pre-compilation output would be useful?

Hi Matteo,

Which .lib file are you trying to use? We've had some issues with the .lib files in the past for this device, but I believe the files in the latest C2000ware version have been fixed.

Can you also verify that you followed the steps in 4.3 Integrating the Library into your Project in the CLA math users guide (linked here) to include the CLA math library in your project? For reference, the F28P65x has the CLA tables hardcoded into the device's ROM, so you should be able to use the datarom variant of the library you choose.

Best Regards,

Delaney

Hi!

I was employing:

cla2_math_library_datarom_fpu32_eabi.lib

cla2_math_library_fpu32_eabi.lib
with .asm file

I tried also to include f28P65xCPU1_CLADATAROM_Symbols_fpu32.lib and the same happens

Hi Matteo,

Ok, yes, I believe there was previously an issue with these files. Which version of C2000ware are you using? It should be updated in the newest release (5.02).

Best Regards,

Delaney

After inspecting a little more it seems that the error is due to the simoultaneous inclusion of math.h and CLAMath.h.

The fact is that we are trying to develop a general library that can be included both in CPU and CLA and there there was some math.h inclusion, after pre-processing substitution tanf declaration in math.h to be subsituted with (CLAsin_inline(m)/CLAcos_inline(m)) which is obviously not okay.

thanks a lot for the support!
