crosstool-works

Patches and configurations to build Linaro toolchains on OS X (>=10.9) host systems. This version provides crosstool-ng patches for various Linaro releases and for target platforms. Patches for further releases may be added to this repository. Please check block page for more details: http://wp.me/p44jAC-2P

Notes

• Patch files located under "patches" directory and named as (crosstool-ng-linaro-version-release).patch
• ctworks.sh script applies patches automatically according to selected crosstool-ng package.
• You can configure ctworks to use with different releases (and patches).

Usage

• Download crosstool-ng packages from Linaro releases storage server (http://releases.linaro.org)

  ./ctworks.sh get

• Create case sensitive file system in a disk image (or you may use existing one):

  ./ctworks.sh create|attach

• Run with "prepare" switch to extract crosstool-ng package and apply patches etc.

  ./ctworks.sh prepare

• Run with "config" switch to configure crosstool-ng and follow instructions displayed to build toolchain

  ./ctworks.sh configure

• Run with "eject" switch to unmount disk image.

  ./ctworks.sh eject

• Notes:

• You may edit ctworks.config file to change your previously saved ctworks-configuration If you remove some lines from this file, it will be asked again.

• You may need to restart from a step when something goes wrong; ./ct-ng list-steps RESTART=libc_start_files ./ct-ng build

Prerequisites

• Xcode and Command line tools

  xcode-select --install

• MacPorts should be installed. Required ports as follows (openwrt requires some of them also);

  sudo port install binutils gawk gsed grep gnutar gmake file findutils unrar wget coreutils e2fsprogs ossp-uuid asciidoc fastjar flex getopt gtk2 intltool jikes hs-zlib p5-extutils-makemaker python26 rsync ruby sdcc unzip bison autoconf help2man

• ln -s /path/to/ports/bin/gsed /path/to/ports/bin/sed
