# GNU Tools for ARM Embedded Processors is a reliable and well-tested toolchain
# available in both source and binaries. It can be downloaded here:
# https://launchpad.net/gcc-arm-embedded

# Also, you can download the pre-built binaries of SAT for Windows here:
# http://dl.bintray.com/content/clouded/Summon-ARM-Toolchain-for-Windows

# Compilation of the Summon ARM Toolchain for Windows may be less painfull if
# it is done through cross-compilation by MinGW on Linux since it's a way to
# avoid a lot of msys problems such as freezes on parallel make jobs, heap 
# problems and lack of tools. 

##############################################################################
# Requirements (for Windows)
##############################################################################

# MinGW - tested version is x32-4.8.0-release-posix-sjlj-rev0 downloaded from
# http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.0

# MSYS - tested version 1.0.11 from 
# http://sourceforge.net/projects/mingw/files/MSYS/Base/msys-core/msys-1.0.11/

# GMP/MPFR/MPC - tested gmp-5.1.1, mpfr-3.1.2, mpfr-2.4.1 built from source.
# Binary versions from http://sourceforge.net/projects/mingw/files/MinGW/Base/
# also seem to be fine, if you want to use them you need dll and dev packages.
# Place dlls in mingw32\bin and unpack dev packages in mingw32\i686-w64-mingw32

# Sources for binutils, gcc, newlib-nano (or newlib) and gdb.
# Download\clone\unpack sections have been removed from the script since 
# msys is lacking a lot of tools and downloading and installing them would
# take the same time as to manually download and unpack needed sources.
# So simply download and unpack into the working directory (i.e. /c/dev):
# http://ftp.gnu.org/gnu/binutils/binutils-2.23.1.tar.bz2
# http://ftp.gnu.org/gnu/gcc/gcc-4.8.0/gcc-4.8.0.tar.gz
# https://github.com/32bitmicro/newlib-nano-1.0/archive/master.zip
# http://ftp.gnu.org/gnu/gdb/gdb-7.5.1.tar.bz2

##############################################################################
# Possible problems and workarounds
##############################################################################

#1
# In case make cannot find gmp\mprf\mpc or if you encounter an error that says
# "Cannot compute suffix" try these options:
#
#GCCFLAGS="${GCCFLAGS} --with-gmp=${MINGW_PATH} --with-mpfr=${MINGW_PATH} \ 
#--with-mpc=${MINGW_PATH} --with-libiconv-prefix=${MINGW_PATH}"
#
# You may also try to set paths to dynamic libraries:
#
#export LD_INCLUDE_PATH=$LD_INCLUDE_PATH:${MINGW_PATH}/include
#export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${MINGW_PATH}/lib

#2
# If you get "couldn't commit memory for cygwin heap" error you can try to:
# Simply re-run the script and since some of the things are already built the
# process will require less memory.
# Disable all antivirus and firewall software.
# Disable\close\stop as much services and programs as possible.
# Download msys of another version.
# Rebase msys-1.0.dll \ rebase all.
