# THIS SCRIPT DOESN'T DO ANYTHING YET!
|
|
#
|
|
# Some things this script could/should do when finished
|
|
#
|
|
# * detect the compiler name (g++/c++/...)
|
|
# * detect whether its a GNU compiler or not (for compiler settings)
|
|
# * detect the host platform and base settings on this:
|
|
# - #defines like -DUNIX and -DMACOSX
|
|
# - required libs like -lmingw32
|
|
# * command line options to...
|
|
# - override the host settings (for cross compiles
|
|
# - select the desired backend (sdl, x11, ...)
|
|
# - whether to do a debug build (with -g) or an optimized build (-O3 etc.)
|
|
# * detect whether the chosen backend is available (e.g. call sdl-config)
|
|
# * generate a config.mak file for use in makefiles
|
|
# * ....
