Now you should also add the toolchain bin directory to your PATH so that the further steps can find the binutils binaries. configure -target=arm-none-eabi -prefix=/opt/mine/arm-none-eabi -enable-interwork -enable-multilib -with-gnu-as -with-gnu-ld -disable-nls But as stated before I am not really sure about that. (Please enlighten me here) But if I understand it correctly the Version 4 EABI is the ARM standarized EABI and not the GNU version of the EABI. I am not 100% sure what the difference is. This way the toolchain builds Version 4 EABI binaries instead of GNU EABI. I call it /opt/mine/arm-none-eabi to distinguish it from other arm toolchains that I have on my machine.

I added it to my path and other relevant environment variables just as I did with /opt/local (the macports install directory). I store everything that I build by myself in /opt/mine directory. Will update that later when I found the right solution. Insight: The versions that I tested for now all had infinite loop bug. So to get it you need to run > svn co -R 1382 svn:///openocd/trunk openocd-svn Openocd: I am using svn version of openocd. The toolchain cannot be installed using stow because of the softlinks it creates. I also use for most of the stuff I use stow. It is needed so that gcc can be compiled. You need to install additionally gmp and mpfr.

I am using macports on my mac, so the howto is based on that. But as I decided to use the newest versions of the tools some things changed and I decided to write my own HowTo. This controller is an ARM Cortex-M3 and needs a GCC version beyond 4.3 because there the support was added. As I decided to use the STM32 for open-bldc and ordered an Olimex H103 evaluation board.
