_Bool is undefined when debugging F28377D CLA

JK Lin

I am debugging cla example projects (v170) on F28377D using CCS 5.5 with compiler version of 6.4.9.

It is good to run the example projects, but the problem occurs when I want to modify the file.

I have ran two projects, "cla_adc_fir32_cpu01" and "cla_vinverse_cpu01". Everything is OK when I am debugging and running the original projects, However, when I want to add a .cla file to "cla_adc_fir32_cpu01" in which "F28x_Project.h" is included , the following errors occur:

line 114,118: error #20: identifier "_Bool" is undefined, in F2837xD_device.h

I have browsed the forum and try to add the definition of _Bool as follow:

#define _Bool bool

But it doesn't work. Then I try another project "cla_vinverse_cpu01" which the cla file is written in .cla instead of .asm in the previous "cla_adc_fir32_cpu01". The only modification in .cla file is to include the header file of F2837xD_device.h, the same problem occurs.

It seems that F2837xD_device.h couldn't been added in .cla file. Is there any guide to solve these problems due to compiler settings? Otherwise it can't read the ADC results or change ePWM settings in .cla file.

Hi,
I have encountered with the same problem a while ago. CLA compiler does not recognize bool type. Either dont include the "F2837xD_device.h" in .cla file or comment "#define _Bool bool" line in the header.

Hmm, well device.h does include stdbool.h which has the definition for _Bool

#define bool _Bool
#if __TI_STRICT_ANSI_MODE__ && 199901L > __STDC_VERSION__
typedef unsigned char _Bool;
#endif

So it should have recognized it unless those macros are not defined when the CLA compiler is invoked. Let me move this over to the compiler forum to get their take on it

For the timebeing you can define this just before you include device.h or project.h in your .cla file

typedef unsigned char _Bool;

Defining "typedef unsigned char _Bool;" yields "invalid combination of type specifiers" error.

Hello KOOSE,

Exclude "F2837xD_device.h" in .cla file works. Thanks.

Hello Vishal,

I have add the following define in device.h:
#ifndef _Bool
#define _Bool unsigned short
#endif
In my case, the project can be built successfully.

I think this is the same situation discussed in this forum post.

Thanks and regards,
