Portmacro.h compile error in 9.0.0

Hello:
I just switched over my code from 8.0.0 (compiled OK) to 9.0.0, where I am getting an error that I don’t understand from the line number it’s reporting.
I am using the ARM_CM3 version of portmacro.h in IAR EWARM. The compile error says this:

Error[Pe018]: expected a “)” C:\Users\grr\Documents\IAR Embedded Workbench\FreeRTOSv9.0.0\FreeRTOS\Source\portable\IAR\ARM_CM3\portmacro.h 144

I don’t see anything wrong with that line, and the corresponding define in the FreeRTOS config looks OK, and it is compiling with 8.0.0.

Thanks for the assistance…

Line 144 is:

#if( configMAX_PRIORITIES > 32 )

so I’m going to guess the problem is with the definition of
configMAX_PRIORITIES in your FreeRTOSConfig.h file.

Ensure configMAX_PRIORITIES is just a number, without any casts.

Removing the cast fixed it. Worked Ok in 8.0.0. Thanks for your help !

.#define configMAX_PRIORITIES ( ( unsigned portBASE_TYPE ) 5 )
