Hello there,

I am trying to setup the tools for debugging and ARM-Cortex M3 microcontroller using Eclipse. I have the project laid out with a custom Makefile and if I build it by simply calling make in the project directory, everything compiles; I flash the binary and it works.

Now, the Makefile uses CodeSourcery Lite tools and explicitly calls for arm-none-eabi-gcc, arm-none-eabi-ld etc. I installed them to /opt/CodeSourcery and modified the PATH so that:

$ echo $PATH

$ ls /opt/CodeSourcery/bin
arm-none-eabi-addr2line arm-none-eabi-gcc-4.5.2 arm-none-eabi-ranlib
arm-none-eabi-ar arm-none-eabi-gcov arm-none-eabi-readelf
arm-none-eabi-as arm-none-eabi-gdb arm-none-eabi-run
arm-none-eabi-c++ arm-none-eabi-gdbtui arm-none-eabi-size
arm-none-eabi-c++filt arm-none-eabi-gprof arm-none-eabi-sprite
arm-none-eabi-cpp arm-none-eabi-ld arm-none-eabi-strings
arm-none-eabi-elfedit arm-none-eabi-nm arm-none-eabi-strip
arm-none-eabi-g++ arm-none-eabi-objcopy
arm-none-eabi-gcc arm-none-eabi-objdump

Now, I cannot understand why Eclipse wouldn't pick up the compiler since the PATH points to the dir where it is.

The error from Eclipse is:
make: arm-none-eabi-gcc: Command not found

Check the variable TOOLCHAIN_AT in (select your project, then rightclick) properties > Resource > Linked Resources

I bet the problem is there - TOOLCHAIN_AT pointing to a location where no tools are. I have the same problem - see also my post under "Access to GNU-Tools"

Just my two cents, when the installer for CodeSourcery runs, it usually defaulted to the /home/<user>/ directory. Not sure if that is what's keeping the toolchain from being discovered by Eclipse. Might want to try a remove, then reinstall of the CodeSourcery toolchain, this time in the /home/<user>/ directory.
