Trying to figure out how to tell Scons to include *2* paths for "fw" includes, include/ and src/. If I have a look in config.log I see

file python/lsst/SConsUtils.py,line 351:
        Configure(confdir = .sconf_temp)
scons: Configure: Checking for C++ header file lsst/fw/Trace.h...

so go into SConsUtils.py, line 351

    for lang in languages:
        conf = self.Clone(CPPPATH = self['CPPPATH'] + [incdir]).Configure()
        foundHeader = conf.CheckHeader(incfiles, language=lang)
        conf.Finish()

So, I *could* edit self.CPPPATH since my change to fw/ups/fw.table's CPPPATH did not work. But this is the kind of hack that RHL yelled at me about. Lets try it to see what works. I want to add into SConstruct

env.Append(CPPPATH=os.path.join(os.environ["FW_DIR"], "src"))
print 'DUH', env['CPPPATH']

but I don't even get past the .sconf_temp/conftest part. This must happen when I initialize env, so env = scons.makeEnv. I notice in SConsUtils.py MakeEnv? subroutine...

    env['CPPPATH'] = []

so it starts off empty, it does not inherit from your environment like e.g. PATH

    env = Environment(ENV = {'EUPS_DIR' : os.environ['EUPS_DIR'],
                             'EUPS_PATH' : os.environ['EUPS_PATH'],
                             'PATH' : os.environ['PATH'],

I guess I am the guinea pig for all this, I am certainly sending off some ignorant sounding emails... I suppose someone has to.

Anyways, a solution is not forthcoming. What to do in this situation? HACK IT!!!!

becker35: cd include/lsst/fw/
becker37: ln -s ../../../src/*cc .
becker64: scons
  ...
  Checking for C++ header file lsst/fw/Trace.h... yes
  ...

At least it fails for my own ineptitude now! :)

Coding Oopses

Code:
      satValue = satPtr.getValue();
Error:
      error: 'class boost::shared_ptr<lsst::DataProperty>' has no member named 'getValue'
Solution:
      satValue = satPtr->getValue();

Code:
      satValue = satPtr->getValue();
Error:
      error: cannot convert `boost::any' to `float' in assignment
Solution:
      satValue = boost::any_cast<const float>(satPtr->getValue());

And, by the way, my code compiles! I have a lot of stuff commented out for now (e.g. Image needs a _metaData accessor like Mask->getMetaData, and all the Variance things). But it compiles! Success!

Uh, I should not have been so quick... I can build the .o file but not the executable, library issues...

Note the problem

Namespace issues?
