# 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 |
dpavlin |
24 |
# o) X11 flags and libraries (TODO: should be possible to override |
51 |
|
|
# via command line options?) |

# The general philosophy regarding command line switches is that anything |
55 |
|
|
# which can be incorporated into the program as a runtime command line option |
56 |
|
|
# should be, instead of requiring a recompile. |
