In the following, I compiled some useful information / links / problems that I encountered during my try to install the ScienceTools myself on a machine at CEA Saclay (i.e., external). No claim of completeness whatsoever, and a lot of these things might be obvious for most.
Look at the ScienceTools scripts online: CVS repository
You need a SLAC user account. If you don't have it, see Obtaining a SLAC account (2014), Setting up SLAC Accounts (2012), Getting a New SLAC Account (~ 2000)
Setting up CVS:
Follow the steps in Using the GLAST SLAC cvs Repository, then
--> write a mail to Thomas Glanzman to get CVS access for your account.
--> you will have to logout and login for the change to take effect.
--> you should have (if you have an external account):
CVSROOT -> :ext:YOURSLACUSERNAME@centaurusa.slac.stanford.edu:/nfs/slac/g/glast/ground/cvs CVS_RSH -> ssh |
Check the available versions of ScienceTools: New Release Manager web interface
How to get the ScienceTools (here, version LATEST-1-4167):
cvs co -r ScienceTools-LATEST-1-4167 ScienceTools-scons |
Get the CVS status:
cvs status |
Get the CVS update:
cvs up |
SCons version SCons 1.3 required (SCons)

Environment variable $GLAST_EXT:
“The environment variable GLAST_EXT should be suitably defined. (...)
Note: The --with-GLAST-EXT option must always be supplied; others are optional under most circumstances.”
This is the variable defining the directory of external programs (e.g. python).
I pointed the GLAST_EXT variable to the ScienceTools RELEASE, which is not the place where I want to install the latest ScienceTools version.
$GLAST_EXT=/dsm/saplxglast/glast/sas/Binary/ScienceTools-RELEASE-10-01-01-sympy |
How to build the ScienceTools:
(assuming you want to build a package called 'astro')
scons --with-GLAST-EXT=${GLAST_EXT} --compile-debug astro |
I put some example output at the end of this page
Remark (python code):
python code, let's say the script foo.py example in
ScienceTools-scons/pointlike/python/uw/like/foo.py |
will be copied to
ScienceTools-scons/python/uw/like/foo.py |
when you build the respective package (here: pointlike. For the example output, see end of this page)
So do not change the code in the python package directly
Remark (dependencies):
SCons should handle dependencies correctly. However, at the moment there seems to be an issue when compiling the skymaps before astro package. Follow this thread:
Obviously, in order to use your brand new installation of the ScienceTools, you would need to adjust your environment.
You might consider changing the following environmental variables:
PATH
ST_INST
INST_DIR
LD_LIBRARY_PATH
TCL_LIBRARY
DYLD_LIBRARY_PATH
PYTHONPATH
## e.g.
export PATH=$MY_ScienceTools:${PATH}:.
|
E.g., one could create a second bashrc script that sets the environment so that you can chose between the 'standard' installation and your own one.
Example output of building with SCons:
jschmid@sappcfermi ScienceTools-scons$scons --with-GLAST-EXT=${GLAST_EXT} --compile-debug pointlike
scons: Reading SConscript files ...
This build is running on: sappcfermi.extra.cea.fr
