Crosstool-ng

Building

You will need to install some packages:

apt-get install gperf texinfo libtool automake bison flex gawk cvs zlib1g-dev

Download from: http://crosstool-ng.org/download/crosstool-ng/

CT_INSTALL_DIR=../crosstool
./configure --prefix=${CT_INSTALL_DIR}
make
make install

Using

To keep a cache of the downloaded sources, do the following

mkdir ~/src

Then configure and build the toolchain!

# pick a default config, or make your own from scratch!
cp ${CROSSTOOL_NG_SRC}/samples/${CHOSEN_SAMPLE}/crosstool.config .config
 
# review / change options
# PREFIX_DIR should be an absolute path (as of writing you can use $(pwd) to make it 'relative')
${CT_INSTALL_DIR}ct-ng menuconfig
 
# build
${CT_INSTALL_DIR}ct-ng build

If everything went smoothly... have a look in ~/x-tools/ (or elsewhere if you changed PREFIX_DIR)
