Hi,
this:
scons: *** [2017-12-08 21:58:35.968302] UnicodeDecodeError : 'ascii' codec can't decode byte 0xf8 in position 96: ordinal not in range(128)
also happens on Linux with python 3.6.3 and scons 3.0.1
with a simpler SConstruct
--------------------------------
import datetime
prog = Program("hello", ["main.cpp"])
run = Command(Value(datetime.datetime.now()), prog, "hello")
Alias("run", run)
--------------------------------
Regards
ml

Hi,
thank you for the effort. The SConstruct that was used in your test does not provoke the issue. I included a SConstruct that fixes the problem for me in the original post. Unfortunately, I cannot apply the fix at every point where this issue haunts me. This is the SConstruct that throws the error (in my setup):
-----------------------------------------
import os
env = Environment(tools = ["mingw"], ENV=os.environ)
prog = env.Program("main", ["main.cpp"])
run = env.Command(Value("test"), prog, "main")
env.Alias("run", run)
env.AlwaysBuild(run)
-----------------------------------------
Sorry for causing confusion. Could you please try again, using above SConstruct?
I encounter this issue with Python 2.7.13 on Windows 7.
$ python --version
Python 2.7.13
$ scons --version

I'm not seeing the failure when I run on my mac:
$ venv/bin/scons -f SConstruct_Broken run

scons: Building targets ...
g++ -o main.o -c main.cpp

Have you looked at?:
