I’m currently struggling to build any of the Demo ports that you have developed. For example, I’m trying to build ARM7_LPC2106_GCC using the GNUARM toolset, once built I’ll modify it for the development board I’m using. From the command line I’m using ‘make’. I get the following output: $ make arm-elf-gcc -c -Wall -Wextra -Wshadow -Wpointer-arith -Wbad-function-cast -Wcast-align -Wsign-compare -Waggregate-return -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wunused -D  -D GCC_ARM7 -I. -I../../Source/include -I../Common/include  -mcpu=arm7tdmi -T ../../Source/portable/GCC/ARM7_LPC2000/portISR.c -o ../../Source/portable/GCC/ARM7_LPC2000/portISR.o arm-elf-gcc: GCC_ARM7: No such file or directory arm-elf-gcc: no input files make: *** [../../Source/portable/GCC/ARM7_LPC2000/portISR.o] Error 1 I don’t have much experience using makefiles and may be doing something very silly – can you please advise?

The string "-D -D GCC_ARM7" shows that there is a definition missing from the environment. Please read the documentation: http://www.freertos.org/portlpc2106.html and / or the readme file in the directory for detailed instructions on how to build the demo.  Batch files are provided to do everything you need. Regards.
