Here are the basic steps to get a +working toolchain: + +* Create a new directory in `$HOME` called `build` + +``` +; cd $HOME; mkdir build; cd build +``` + +* Clone the crosstool-ng git repository + +``` +; git clone https://github.com/crosstool-ng/crosstool-ng && cd crosstool-ng +``` + +* Install the required dependencies for using ct-ng + +``` +; sudo apt-get install build-essential autoconf automake ncurses-dev gperf flex texinfo help2man libtool-bin +``` +* Compile crosstool-ng + +``` +; ./bootstrap +; ./configure --prefix=$HOME/.local +; make +; make install +``` + +Now you have installed crosstool-ng. Now let's create an armhf toolchain! +Go grab some beer and drink it until it's done compiling... + +``` +; export PATH="$HOME/.local/bin:$PATH" +; mkdir -p $HOME/tc/armv7-rpi2-linux-gnueabihf +; cd $HOME/tc/armv7-rpi2-linux-gnueabihf +; ct-ng armv7-rpi2-linux-gnueabihf +; ct-ng build +``` + +Congrats! You've built a GCC toolchain and perhaps got drunk in the meantime :) + +Be sure to check out `ct-ng list-samples` to see what other toolchains are +offered, or perhaps even configure your own with `menuconfig`
