 Using crosstool-NG on FreeBSD (and other *BSD) |

 -----------------------------------------------+

 Contributed by: Titus von Boxberg

 Prerequisites and instructions for using ct-ng for building a cross toolchain on FreeBSD as host.

 0) Tested on FreeBSD 8.0

 1) Install (at least) the following ports

    archivers/lzma

    textproc/gsed

    devel/gmake

    devel/patch

    shells/bash

    devel/bison

    lang/gawk

    devel/automake110

    ftp/wget

    Of course, you should have /usr/local/bin in your PATH.

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

    ./configure --with-sed=/usr/local/bin/gsed --with-make=/usr/local/bin/gmake \

    --with-patch=/usr/local/bin/gpatch

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

 3) proceed as described in general documentation

    but use gmake instead of make

 Using crosstool-NG on MacOS-X |

 ------------------------------+

 Contributed by: Titus von Boxberg

 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

 HINTS:

 - Apparently, GNU make's builtin variable .LIBPATTERNS is misconfigured

   under MacOS: It does not include lib%.dylib.

   This affects build of (at least) gdb-7.1

   Put 'lib%.a lib%.so lib%.dylib' as .LIBPATTERNS into your environment

   before executing ct-ng build.

   See http://www.gnu.org/software/make/manual/html_node/Libraries_002fSearch.html

   as an explanation.
