#
# tested on | Windows native | Linux cross-compilation
# ------------------------+-------------------+---------------------------
# MSVS C++ 2010 Express | WORKS | n/a
# Mingw-w64 | WORKS | WORKS
# Mingw-w32 | WORKS | WORKS
# MinGW | WORKS | untested
#
#####
# Notes about MSVS C++ :
#
# - MSVC2010-Express compiles to 32bits only.
#
#####
# Notes about Mingw-w64 and Mingw-w32 under Windows :
#
# - both can be installed using the official installer :
# http://mingw-w64.sourceforge.net/download.php#mingw-builds
#
# - if you want to compile both 32bits and 64bits, don't forget to
# run the installer twice to install them both.
#
# - install them into a path that does not contain spaces
# ( example : "C:/Mingw-w32", "C:/Mingw-w64" )
#
# - if you want to compile faster using the "-j" option, don't forget
# to install the appropriate version of the Pywin32 python extension
# available from : http://sourceforge.net/projects/pywin32/files/
#
# - before running scons, you must add into the environment path
# the path to the "/bin" directory of the Mingw version you want
# to use :
#
# set PATH=C:/Mingw-w32/bin;%PATH%
#
# - then, scons should be able to detect gcc.
# - Mingw-w32 only compiles 32bits.
# - Mingw-w64 only compiles 64bits.
#
# - it is possible to add them both at the same time into the PATH env,
# if you also define the MINGW32_PREFIX and MINGW64_PREFIX environment
# variables.
# For instance, you could store that set of commands into a .bat script
# that you would run just before scons :
#
# set PATH=C:\mingw-w32\bin;%PATH%
# set PATH=C:\mingw-w64\bin;%PATH%
# set MINGW32_PREFIX=C:\mingw-w32\bin\
# set MINGW64_PREFIX=C:\mingw-w64\bin\
#
#####
# Notes about Mingw, Mingw-w64 and Mingw-w32 under Linux :
#
# - default toolchain prefixes are :
# "i586-mingw32msvc-" for MinGW
# "i686-w64-mingw32-" for Mingw-w32
# "x86_64-w64-mingw32-" for Mingw-w64
#
# - if both MinGW and Mingw-w32 are installed on your system
# Mingw-w32 should take the priority over MinGW.
#
# - it is possible to manually override prefixes by defining
# the MINGW32_PREFIX and MINGW64_PREFIX environment variables.
#
#####
# Notes about Mingw under Windows :
#
# - this is the MinGW version from http://mingw.org/
# - install it into a path that does not contain spaces
# ( example : "C:/MinGW" )
# - several DirectX headers might be missing. You can copy them into
# the C:/MinGW/include" directory from this page :
# https://code.google.com/p/mingw-lib/source/browse/trunk/working/avcodec_to_widget_5/directx_include/
# - before running scons, add the path to the "/bin" directory :
# set PATH=C:/MinGW/bin;%PATH%
# - scons should be able to detect gcc.
#
#####
# TODO :
#
# - finish to cleanup this script to remove all the remains of previous hacks and workarounds
# - make it work with the Windows7 SDK that is supposed to enable 64bits compilation for MSVC2010-Express
# - confirm it works well with other Visual Studio versions.
# - update the wiki about the pywin32 extension required for the "-j" option under Windows.
# - update the wiki to document MINGW32_PREFIX and MINGW64_PREFIX
