[Scons-users] Error while refreshing build settings

[Michael Potter]

I am a new user to SConsolidator/Eclipse/SCons.  I am working with a
pure C project.

When I click the Swiss Flag Icon to refresh my build settings from my
hand codes SConstruct file, I get this error:

=== Running SCons at 2/12/13 4:03 PM ====

  File "/usr/lib/python2.6/subprocess.py", line 1228:
    raise child_exception
Duration 608 ms.

My SConstruct file looks like this:
VariantDir('build', '.')
SConscript('build/src/SConscript')

My src/SConscript file looks like this:
env = Environment(CPPPATH = ['.', '..', '/usr/include'])
env.Program('dumpstatus', ['dumpstatus.c', 'logger.c'])

I can build without error.

The /home/pottmi/mypro/mypro/ProjectInfoExtractor.py file does not
exist after the error so I cannot use that to debug.

Questions are:
1) What can I do to fix this?
2) What can I do to debug this in the future when I get similar problems?
