31 #
32 # This is a minimal configure script, hardcoded for GXemul. This script
33 # figures out which compiler flags will work, and creates Makefiles in
34 # sub-directories. A config.h file is also created.
35 #
36 #
37 # ---> FOR NORMAL USE, JUST RUN ./configure WITHOUT OPTIONS!
38 #
39 #
40 # To compile the emulator with profiling (during development), use
41 # CFLAGS="-pg", run the emulator, and then run 'gprof gxemul' and study
42 # the results.
43 #
44 #
45 # The main things that are detected by this script:
46 #
47 # o) special hacks for some OSes
48 # o) which compiler to use (overridden by setting CC)
49 # o) which compiler flags to use (overridden by setting CFLAGS)
50 # o) X11 flags and libraries (TODO: should be possible to override)
51 # o) binary translation (on supported platforms)
52 #
53 # TODO:
54 # o) X11 libs and includes via command line options?
