[Buildbot-devel] Using a Factory with Another Factory

[Razvan Lupusoru]

Hello,

I am trying to load a factory within another factory. This is done like 
this:
####
factory_gcc_EM64T = factory.BuildFactory()
factory_gcc_EM64T.addStep(ShellCommand(command=["/bin/env"],
                                        env={'NOWINSTALLPATH': 
'gen2-gcc-em64t'}))
factory_gcc_EM64T.addStep(compileAndBuildFactory) # Add compilation 
abilities

compileAndBuildFactory= factory.BuildFactory()
compileAndBuildFactory.addStep(SVN(mode='update', baseURL=SVN_URL, 
defaultBranch='trunk'))
####

The reason I am doing this is because I need my first factory to set 
some environment variables which will be used by compileAndBuildFactory 
so that it stays a generic factory that I can reuse. The configuration 
file passes the buildbot checkconfig option. However, whenever I start a 
build, I get the error: SetupBuild Exception
This is from the twisted.log file:

Is my syntax for loading a factory within a factory wrong? Is there any 
better way to set some environment variables based on what which builder 
is called and then do some generic steps?

Thank you,
