Dear Loris,
one way to achieve what you want is to use the modxxxfooter parameters in the
eb-file (untested):
modluafooter = 'setenv("MCR_CACHE_ROOT", pathJoin("/scratch",
pathJoin(os.getenv("USER"), "mcr_cache")))'
modtclfooter = 'setenv("MCR_CACHE_ROOT", pathJoin("/scratch",
pathJoin(os.getenv("USER"), "mcr_cache")))'
Not sure if this is advisable, in particular if you use $TMPDIR as this may
change from the time the module is loaded to the time Matlab is running.
Wouldn't it be better to set MCR_CACHE_ROOT within Matlab based on TMPDIR?
Best wishes
Stefan

Betreff: Re: [easybuild] Accessing environment variables in easyconfig
Hi Åke,
I want to add the environment variables to a MATLAB easyconfig which are needed
to run compiled MATLAB programms
I tried
modextravars = {'LM_LICENSE_FILE': '%s@%s' % (license_server_port,
license_server),
'MATLABROOT': '.',
'MCR_HOME': 'MATLABROOT',
'MCR_CACHE_ROOT': '/scratch/$USER/mcr_cache',
}
But when I load the module as a normal user, the variable is not
expanded:
$ echo $MCR_CACHE_ROOT
/scratch/$USER/mcr_cache
Ultimately, I may well just define a general temporary directory such as
TMPDIR=/scratch/tmp/$USER
somewhere in /etc/profile.d, but even then I'd need to have the module expand
$TMPDIR properly.
Cheers,
Loris
