[Scons-users] chdir and parallel builds

[Brian Cody]

Yeah, it's broken as far as we're concerned. I'm not sure why it doesn't
work this way inside SCons, but we have a workarounds module with this
function:

def execute_in_directory(env, dir, command, shell=False):
    # http://scons.tigris.org/issues/show_bug.cgi?id=2597
    proc = subprocess.Popen(command, env=_get_current_environment(env),
cwd=dir, shell=shell)
    return proc.wait()

def _get_current_environment(env):
    asciienv = {}
    for key in env['ENV']:
        asciienv[key] = str(env['ENV'][key])
    if not isinstance(env['ENV']['PATH'], basestring):
        asciienv['PATH'] = os.pathsep.join(env['ENV']['PATH'])
    return asciienv

If there's an easier way...
