# This will build ALL variants!
#
# This expects the following environment variables set:
#
# COMPILE_OS      - linux, macosx, windows
# COMPILE_OS_ARCH - 32, 64, arm
#
#
# possible packages you might need in order to compile:
#  gcc-4.8 gcc-4.8-multilib g++-4.8-multilib gdb make libgtk2.0-dev libxtst-dev libc6-dev-i386 mingw-w64
#  ccache libssl0.9.8
#
# Then, in gcc_apple_amd64 dir: sudo dpkg -i *.deb (this is 64bit gcc to build macosx binaries)
#
# Because we fake the 32bit/arm library calls during compile time (the libs are
# loaded during run time) we can build 32bit/arm builds on a 64bit system without needing multi-arch
# GTK libraries (fyi: there aren't any... and DO NOT install the i386 ones, since they will REMOVE what
# you already have - buggering your system!)
#
#
#
# TODO: clean up below, verify arm builds.
#  # arm:  gcc-arm-linux-gnueabi gcc-4.8-arm-linux-gnueabihf
# hf or no hf? beaglebone, rasbpi, ODROID-U3, other ARM devices
#
# ARMv7sf needs gcc-arm-linux-gnueabi, ARMv7hf needs gcc-arm-linux-gnueabihf
#
# To compile for the ARMv7 (BeagleBone Black), follow:
# http://www.michaelhleonard.com/cross-compile-for-beaglebone-black/
#
# for raspi/BBB

#
#
#for ANY OTHER OS/ARCH, the easiest, and most straight forward method is to use
# crosstool-ng. http://crosstool-ng.org/

# as per: http://stackoverflow.com/questions/8937492/what-is-upxs-best-compression-method
# it is NOT a good idea to compress exe's. WHY? Because they run slower, and HDD space is no longer a concern.
# especially since the executable is ~ 500k.
