Crosstool-NG follows the autoconf dance. So, to get you kick-started, just run:
./configure --help
If you are using a development snapshot, you'll have to create the configure script, first. Just run:
./bootstrap
You will find the documentation in the directory docs.
To build in one go, run the following:
./bootstrap && ./configure --prefix=`pwd` && make MAKELEVEL=0 && make install MAKELEVEL=0
This fork of crosstool-NG add a Docker image so you can download the final build without the hassle of a looong compile time.
docker run --rm -it -v $PWD:/home/project homebotz/crosstool-ng
