Ubuntu ARM toolchain compiles Stellaris USB examples correctly

I managed to get the StellarisWare libraries and examples working without Sourcery Codebench. Based on these two articles:

The complete StellarisWare suite compiles without errors, and the examples I tried (including usb_dev_serial and usb_dev_mouse) work correctly. This is an improvement over summon-arm-toolchain, which compiled non-functional USB examples.

Instructions for Ubuntu 12.10:

  1. # Install toolchain
    sudo aptitude install gcc-arm-linux-gnueabi
    # Download and compile newlib (had trouble with the toolchain's libc and libm)
    wget ftp://sources.redhat.com/pub/newlib/newlib-1.18.0.tar.gz
    tar xzf newlib-1.18.0.tar.gz
    cd newlib-1.18.0/
    ./configure --target arm-linux-gnueabi --disable-newlib-supplied-syscalls

    This makes the files libc.a and libm.a in the subdirectory arm-linux-gnueabi/newlib

  2. Unzip the StellarisWare files, and in the root directory edit makedefs. Search for the following settings and change them, replacing something with the directory where you unzipped newlib

    Also change CFLAGS, adding the line with -fno-stack-protector, so it looks like this:

    CFLAGS=-mthumb             \
           ${CPU}              \
           ${FPU}              \
           -Os                 \
           -ffunction-sections \
           -fdata-sections     \
           -MD                 \
           -std=c99            \
           -Wall               \
           -pedantic           \
           -DPART_${PART}      \
           -fno-stack-protector \
  3. To compile everything, run make clean and make
