Hello,
I opended the following project FreeRTOSV8.2.3.exe > FreeRTOS > Demo > ARM7_LPC2368_Eclipse
with current eclipse-cpp-mars-1-win32-x86_64
and GNU Tools ARM Embedded gcc-arm-none-eabi-5_2-2015q4-20151219-win32.exe
and GNU ARM Eclipse Build Tools gnuarmeclipse-build-tools-win64-2.6-201507152002-setup.exe
under Windows 7 x64

While installation I replaced all . by _ because I read that . in path could cause problems.

I get the following error:
Program “arm-elf-gcc” not found in PATH

Resolution from http://stackoverflow.com/questions/20412100/discovery-options-in-eclipse-c-c
Kepler hides “Discovery Options” by default. Go to Window->Preferences-> C/C++ > Property Pages Settings and check display discovery option page. Then, open your project preferences and change arm-elf-gcc to arm-none-eabi-gcc like the rest.

I tested this but I couldn’t find the option.

Resolution from https://wiki.ubuntuusers.de/Archiv/GNUARM-Toolchain/
Das PPA installiert arm-none-eabi-gcc, nicht arm-elf-gcc wie im Rest des Tutorials. Das Target arm-elf wird ab GCC 4.8 nicht mehr unterstützt. In der Bedienung unterscheiden sich arm-none-eabi-gcc und arm-elf-gcc nicht.

GCC after 4.8 no longer support arm-elf-gcc.

What can I do now?

This is my board: http://www.micro4you.com/files/lpc2368/ARM7_LPC2368.pdf
I plan to flash the generated .hex-file via UART-0 with Flash Magic.

Thank you.

Do you have the arm-none-eabi-gcc compiler installed on your host and in the system path? It is not part of the Eclipse install and installed separately.

C:\Users\blueicehaller>arm-none-eabi-gcc
arm-none-eabi-gcc: fatal error: no input files

Can I get it to work if I create symlink named arm-elf-gcc to gcc-arm-none-eabi ?

That means the compiler is installed. What is the issue you have then? If it is calling arm-elf-gcc but the compiler is arm-none-eabi-gcc then you will need to update the project to use the right compiler.

I believe I found the location where I have to set this, see “Properties for RTOSDemo.png”
I also changed line 60

55 RTOS_SOURCE_DIR=../../../Source
56 DEMO_COMMON_DIR=../../Common/Minimal
57 DEMO_INCLUDE_DIR=../../Common/include
58 UIP_COMMON_DIR=../../Common/ethernet/uIP/uip-1.0/uip
59 
60 CC=arm-none-eabi-gcc      # previous value: arm-elf-gcc
61 OBJCOPY=arm-elf-objcopy
62 LDSCRIPT=lpc2368.ld

Should I change something other than “Compiler invocation command”?

What I found is “FreeRTOSConfig.h” - is this the missing file?

Also I found the following: http://gnutoolchains.com/arm-elf/
Should I test this or another older arm-elf-gcc?
