HI,

we also facing the same problem. when we try to convert and compile the FreeRTOS in pic18f4550 (using mplab ide + microchip c18 compiler) , it failed the compilation


the output shows below


Clean: Deleting intermediary and output files.
Clean: Done.
Executing: "C:\MCC18\bin\mcc18.exe" -p=18F4550 /i"F:\FreeRTOSV4.6.1\FreeRTOS\Demo\Common\include" -I"F:\FreeRTOSV4.6.1\FreeRTOS\Demo\PIC18_MPLAB" -I"F:\FreeRTOSV4.6.1\FreeRTOS\Source\include" "integer.c" -fo="integer.o" -Ou- -Ot- -Ob- -Op- -Or- -Od- -Opa-

Halting build on first failure as requested.
BUILD FAILED: Wed Dec 19 10:47:10 2007

i checked the portable.h file it shows the following area contain the error

/*
* Setup the stack of a new task so it is ready to be placed under the
* scheduler control. The registers have to be placed on the stack in
* the order that the port expects to find them.
*/
portSTACK_TYPE *pxPortInitialiseStack( portSTACK_TYPE *pxTopOfStack, pdTASK_CODE pxCode, void *pvParameters );

any help on this matter would be greatly appreciated.

Thanks in advance,
