[Scons-users] Windows installer for SCons 3.0.1

[Steve Hill (Wireless)]

All,

We are planning to upgrade to MSVS2017 so we need to move to SCons 3.0.1. However, when I click on the download link for the Windows installer on https://scons.org/pages/download.html, it appears not to exist - I just get taken to a SourceForge page that offers me a .zip file. How do I go about getting a Windows installer for the latest production version of SCons?

Thanks in advance,

Steve.

Steve,

We've dropped the windows installer in favor of pip install.
Please give that a try.

Which version of Python are you planning on using it with?

I recommend running:
python -mpip install -U pip
python -mpip install scons

(To ensure you have the latest pip installed, and pip installing scons
requires a fairly recent version)

Hi Bill,

Thanks for this. It might be worth updating the downloads page with this information?

We are currently using 2.7.12 32-bit (though we also use 3.6.3 for 64-bit duties and may look forward to switching over this at some point in the future.)

The install seems to have gone well using the commands that you gave below. The only issue that I have with using PIP is that we need to support having multiple versions of SCons installed against the same python install; is this possible?

Thanks again,

S.

Steve,

In that case, virtualenv is your friend

virtualenv scons-#.#.#
scons-#.#.#\scripts\activate.bat
pip install -U pip
pip install scons

You can create one virtualenv per scons version.

my relatively rarely-used Windows setup has one py2+scons3 setup and one
p3+scons3 setup, and this works well.

on the other hand, if the issue is different projects using different
scons versions, adding a local-install scons to the project could also
work. that way you're sure to have the right one - have done that
experimentally and it seems to work fine too.

Thanks Bill.

I don’t think that virtualenv is going to work for us. As Mats said, we have different projects using different SCons versions and we have a switch over period between two versions of SCons for any given project, where multiple version are permitted. The standard script that implements this is:

#! /usr/bin/env python
import os, sys

# Define the list of allowed SCons versions, in priority order - with the preferred versions first
versions = [
("2.5.1", ""),
("3.0.1", ""),
]

forced = False

# The first argument maybe the specific version of SCons to use so check for that...
if len(sys.argv) > 1:
for version, flags in versions:
if sys.argv[1] == version:
print "Forcing to SCons version", version
forced = True
versions = [
(version, flags)
]
del sys.argv[1]
break

for version, flags in versions:
batchFile = os.path.join(os.path.dirname(sys.executable), 'Scripts', 'scons-%s.bat' % version)
if os.path.exists(batchFile):
cmd = '\"%s\" %s ' % (batchFile, flags) + ' '.join(defaults + sys.argv[1:])
sys.exit(os.system(cmd))
else:
if forced:
print "SCons version", versions[0][0], "is not installed"
else:
print "No supported version of SCons is installed"

This allows all the users to have multiple versions of SCons installed and each project will use the version that is to be used for that project – or fail if it is not currently installed. I’ll have to look at whether I can create a .zip file for each version of SCons 3.x.x that we end up using to allow multiple concurrent installations


Thanks,

S.

Steve,

There no reason your script can't be modified to work with virtualenvs.

Just create a virtualenv at:

c:\scons\3.0.1
c:\scons\2.5.1

And then modify your script to use c:\scons as the base instead of <python
install>\scripts\...
If you want a version per python version, similar path nameing should also
do the trick.

Just a quick update. I’ve had a reasonably willing victim install SCons 3.0.1 with pip (against Python 2.7.12) and he needed to run the following sequence before it would install without errors:

python -m pip install -U pip
python -m pip install -U setuptools
python -m pip install -U wheel
python -m pip install scons

S.

[Bill Deegan]

Yes.
That's as I'd expect.
