# 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 |
# o) prefetch capability (TODO: this is assumed on Alpha, but not all |
53 |
# Alphas have it...) |
54 |
# |
55 |
# TODO: |
56 |
# o) do not enable prefetch on Alpha ev4 or ev5, only on pca56 and newer |
57 |
# o) X11 libs and includes via command line options? |
