Hi, Using the new version of FreeRTOS I get always this error: Source/portable/GCC/ARM_CM3/portmacro.h:91:23: error: missing binary operator before token “long” ~~~~~~~~~~~~~~~~~~ /* Type definitions. */

define portCHAR char

define portFLOAT float

define portDOUBLE double

define portLONG long

define portSHORT short

define portSTACKTYPE uint32t

define portBASE_TYPE long <—- HERE

typedef portSTACKTYPE StackTypet; typedef long BaseTypet; typedef unsigned long UBaseTypet; ~~~~~~~~~~~~~~~~~~ (sorry I read the formating help, I can’t figure out how to highlight this small c code, why not using simple code???) The error is not related with the uint32_t before (it remains when I comment the line). Someone can help me? Regards, O.

The error doesn’t seem to make any sense when viewed in isolation as ‘long’ is obviously a standard C type, but this is a #define so the error must be coming from where the #define is actually used in the source code. Which file is being compiled when portmacro.h gets included? Maybe it would help if you posted the all the compiler output (not of the whole build – just the output when you try recompiling after this error has been output). Regards.

Here is the compilation error (removed some path data for confidentiality) ~~~~~~~~~~~~~~~~ make -r all Building file: ../Source/portable/MemMang/heap3.c Invoking: MCU C Compiler arm-none-eabi-gcc -std=gnu99 -DREDLIB -DDEBUG -DCODE_RED -DCORE_M3 -DUSELPCOPEN -DLPC17XX -I”/frtos/Source/include” -I”/frtos/Source/portable/GCC/ARMCM3″ -I”/lpcboardnxplpcxpresso1769/inc” -I”/lpcchip175x6x/inc” -Og -g3 -Wall -c -fmessage-length=0 -fno-builtin -ffunction-sections -fdata-sections -mcpu=cortex-m3 -mthumb -specs=redlib.specs -MMD -MP -MF”Source/portable/MemMang/heap3.d” -MT”Source/portable/MemMang/heap3.o” -MT”Source/portable/MemMang/heap3.d” -o “Source/portable/MemMang/heap3.o” “../Source/portable/MemMang/heap3.c” In file included from /frtos/Source/include/portable.h:321:0, from /frtos/Source/include/FreeRTOS.h:100, from ../Source/portable/MemMang/heap3.c:85: /frtos/Source/portable/GCC/ARMCM3/portmacro.h:90:23: error: missing binary operator before token “long” #define portBASETYPE long | ~~~~~~~~~~~~ Regards,

Oups, there is also: /frtos/Source/include/FreeRTOSConfig.h:74:44: note: in expansion of macro ‘portBASETYPE’ #define configMAXPRIORITIES ( ( unsigned portBASETYPE ) 8 ) ^ /frtos/Source/portable/GCC/ARMCM3/portmacro.h:166:7: note: in expansion of macro ‘configMAXPRIORITIES’ #if( configMAXPRIORITIES > 32 )

Very curious – it is compiling heap3.c, but heap3.c does not make any reference to portLONG. In fact, portLONG has not been used in the code for a very long time and its definition is just maintained for backward compatibility with some old demos. Is it possible there are some version mismatches somewhere? What is the version number at the top of heap_3.c? Regards.

That one is not so mysterious. Just take the cast off the front of the 8, so it becomes:

#define configMAX_PRIORITIES ( 8 )

Regards.

Thank you, it works. I’ve learned something today 🙂 Regards, O.
