# !/bin/sh
#
# script for compiling and installing YAP under msys. Uses a mingw64
# compiler, msys shell and nsis to do the installing
# Please read the script before trying to execute it.
# Legal arguments for the script are
#  'threads' - enable threads
#  'no_threads',
#  '32', '64'  - compile for 32 or 64 bit architecture.
# By default threads are turned off and we use 64 bits.
#
# please check if you have gcc 64 bits in your path and a clone
# of msys shell like smartgit:
#
# http://sourceforge.net/projects/mingwbuilds/
#   PS: don't install in the default location.
#   mingw should avoid space in its directory path,
#   it freaks winres out.
