 Prerequisites and instructions for using crosstool-NG for building a cross

 toolchain on MacOS as host.

 0) Mac OS Snow Leopard, with Developer Tools 3.2 installed, or

    Mac OS Leopard, with Developer Tools & newer gcc (>= 4.3) installed

    via macports

 1) You have to use a case sensitive file system for ct-ng's build and target

    directories. Use a disk or disk image with a case sensitive fs that you

    mount somewhere.

 2) Install macports (or similar easy means of installing 3rd party software),

    make sure that macport's bin dir is in your PATH.

    Furtheron assuming it is /opt/local/bin.

 3) Install (at least) the following macports

    ncurses

    lzmautils

    libtool

    binutils

    gsed

    gawk

    gcc43 (only necessary for Leopard OSX 10.5)

    On Leopard, make sure that the macport's gcc is called with the default

    commands (gcc, g++,...), e.g. via macport gcc_select

 4) run ct-ng's configure with the following tool configuration

    (assuming you have installed the tools via macports in /opt/local):

    ./configure --with-sed=/opt/local/bin/gsed           \

                --with-libtool=/opt/local/bin/glibtool   \

                --with-objcopy=/opt/local/bin/gobjcopy   \

                --with-objdump=/opt/local/bin/gobjdump   \

                --with-readelf=/opt/local/bin/greadelf   \

                [...other configure parameters as you like...]

 5) proceed as described in standard documentation
