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

[Terry.Rankine at csiro.au]

Hi Brad

We have a 'launcher' file which does this

icc_do my_command arg1 arg2 .... argn

icc_do does the iccvars load and then runs your the rest of the command line.

it was the easiest / lazyiest way we could work out how to do it.

the icc_do was checked in with the source, and also had some CC flags set which we wanted to always happen on compiles.

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

the temptation :-)]
