[Buildbot-devel] Updating / reusing an environment (in a later buildstep)

[Brad Hards]

Hi,

I'm trying to set up a builder that uses icc (where the system default is
gcc). To get the icc / icpc stuff to work, I need to set the right environment.

So the first part of the build factory looks like:
iccenv={'PATH' : '/usr/local/samba/bin:/usr/local/bin:/bin:/usr/bin',
        'CC' : 'icc', 'CXX' : 'icpc'}

fullcheckoutwithicc = factory.BuildFactory()
fullcheckoutwithicc.addStep(ShellCommand(command="/opt/intel/Compiler/11.1/046/bin/iccvars.sh ia32", env=iccenv, flunkOnFailu\
re=True))
fullcheckoutwithicc.addStep(SVN(mode='clobber', svnurl=svnrepository))
fullcheckoutwithicc.addStep(ShellCommand(command=["./autogen.sh"], env=iccenv))
fullcheckoutwithicc.addStep(Configure(command=["./configure", "--prefix=/usr/local/samba"], env=iccenv))

That doesn't work though - the earlier buildsteps don't affect the env that
is passed to later steps.

The only way I can think to make this work is to manually set all of the
environment variables that the "iccvars.sh" script handles. That (obviously) 
isn't very elegant though. 

Any suggestions?

Brad
