33# SCons top-level build description (SConstruct) file.
34#
35# While in this directory ('m5'), just type 'scons' to build the default
36# configuration (see below), or type 'scons build/<CONFIG>/<binary>'
37# to build some other configuration (e.g., 'build/ALPHA_FS/m5.opt' for
38# the optimized full-system version).
39#
40# You can build M5 in a different directory as long as there is a
41# 'build/<CONFIG>' somewhere along the target path. The build system
42# expects that all configs under the same build directory are being
43# built for the same host system.
44#
45# Examples:
46#
47# The following two commands are equivalent. The '-u' option tells
48# scons to search up the directory tree for this SConstruct file.
49# % cd <path-to-src>/m5 ; scons build/ALPHA_FS/m5.debug
50# % cd <path-to-src>/m5/build/ALPHA_FS; scons -u m5.debug
51#
52# The following two commands are equivalent and demonstrate building
53# in a directory outside of the source tree. The '-C' option tells
54# scons to chdir to the specified directory to find this SConstruct
55# file.
56# % cd <path-to-src>/m5 ; scons /local/foo/build/ALPHA_FS/m5.debug
57# % cd /local/foo/build/ALPHA_FS; scons -C <path-to-src>/m5 m5.debug
58#
59# You can use 'scons -H' to print scons options. If you're in this
60# 'm5' directory (or use -u or -C to tell scons where to find this
61# file), you can use 'scons -h' to print all the M5-specific build
62# options as well.
