Hello,
I have some problems building M5 on my Windows system. I pulled the latest
development version of M5 (at least I think so: from http://repo.m5sim.org I
clicked "m5" and then "bz2"; there's no documentation on this :-) ). The first
problem I ran into is that the Python script SConstruct in the root directory
(not the one under src/) is written under the false assumption that all OSs use
"/" as directory separator in paths. In the script, I replaced this:
path_dirs = t.split('/')
try:
build_top = rfind(path_dirs, 'build', -2)
except:
print "Error: no non-leaf 'build' dir found on target path", t
Exit(1)
this_build_root = joinpath('/',*path_dirs[:build_top+1])
with this:
split_path = splitpath(t)
variant = ""
while split_path[1] != "build" and (split_path[0] != "" or split_path[1] !=
""):
variant = split_path[1]
split_path = splitpath(split_path[0])
if split_path[1] == "":
print "Error: no non-leaf 'build' dir found on target path", t
Exit(1)
this_build_root = joinpath(split_path[0], split_path[1])
I also replaced this:
variant_path = joinpath('/',*path_dirs[:build_top+2])
with this:
variant_path = joinpath(this_build_root, variant)
The problem with the previous code is that the variable t doesn't get split, so
the "build" directory is not found with rfind (apparently you are also supposed
to manually create the "build" etc. directories before running scons, something
I think should be mentioned in the compilation instructions). With the above
changes (which I think should work on Unix systems as well), I got a little
further. However, now I get:
Error: Don't know what compiler options to use for your compiler.
Please fix SConstruct and src/SConscript and try again.
Any ideas on how to get past this? Thankful for any help!
My platform is the following:
Windows 7 64-bit
Cygwin g++ version 4.3.4
Win32 Python version 2.7
Cygwin SWIG version 1.3.40
Cygwin zlib version 1.2.3
Cygwin m4 version 1.4.14
Kind regards
