New to FreeRTOS. Trying to build the LPC2129 demo project in IAR. I get this error: Error[25]: #error ‘This file should only be compiled by ICCARM/AARM Fiddled with the compiler settings to no avail. Thanks Rich

Can you please post which file this is in.

portasm.s79 an assembler error Thanks

Hmm, I can’t find a copy of that file with that #error message in. I’m going to assume it is coming from the fact that the asm file in including FreeRTOSConfig.h, and that FreeRTOSConfig.h in including iolpc2129.h – in which case the #error might be in iolpc2129.h. Alternatively it might be a compiler version mismatch issue. If iolpc2129.h contains something the assembler can’t cope with then you can use a guard around the header to ensure it is only included when .c files are compiler rather than assembly files:

#ifdef __ICCARM__
#include 
#endif

Richard, That was nice bit of sleuthing! Adding the compile conditional to FreeRTOSConfig.h allows it to build. Onward and thank you Rich
