[Scons-users] env.Command and _process_ environment variables :-(

[Pedro Larroy]

Hi William

Thanks a lot for your reply. I'm using Visual studio 2012, the problem
only happens in VS2012 with Windows7. In windows 8 the path of the
environment was propagated fine IIRC.

I tried now with env = Environment(ENV={PATH: os.environ['PATH']})
and it works, but before I was doing env = Environment(ENV=os.environ)
hoping to export the full env and didn't work

I'm creating the environment as:

env = Environment(MSVS_ARCH='amd64', MSVC_VERSION='11.0', ENV={'PATH':
os.envrion['PATH']})

And as you say, compiling SConscript files is fine, as CL is found
automatically, the only problem was when calling env.Command oddly
enough.

Pedro.
