This is a short set of instructions for installing the DESDM EUPS system in your machine. For more detail please refer the official EUPS installation guide 

1) Prerequisites for OSX (10.7-10.11)

1a) Xcode

DESDM eups uses Darwin's cc (clang compiler), so you will need to have Xcode installed. You will need a free developer's account to download them.

For a complete set of instructions, please see the complete list of pre-requisites packages.

For OSX 10.7 you can use Xcode (4.6.2) dmg

For OSX 10.8 and 10.9 you can use Xcode (5.1.1) dmg

For Yosemite (OSX 10.10) we strongly recommend Xcode 6.3.1.

For El Capitan (OSX 10.11) we recommend Xcode 7.3.1

 

Make sure that you've agreed to the Xcode license agreements, please run 'xcodebuild -license.'

sudo xcodebuild -license

The command line developer tools are also required, please run:

xcode-select --install

1b) Gfortran

Unfortunately Apple does not ship with gfortran. Get the gfortran dmg image from: https://gcc.gnu.org/wiki/GFortranBinaries

1c) GCC for Darwin.

For Darwin only, in addition to cc (clang) we also need gcc to compile atlas_netlib and scamp. 

You can automatically install them (as sudo/root) on Darwin using the following script: install_gcc_Darwin.sh

chmod +x install_gcc_Darwin.sh
./install_gcc_Darwin.sh

We strongly advise to use the following gcc distributions for OS X from http://hpc.sourceforge.net/

1d) X11/XQuartz

Unfortunately Apple does not ship with X11 either. Download and install the latest image for XQuartz.

2) Decide on the location to install EUPS

For example if you want to install in the user local space ~/EUPS_DESDM

mkdir $HOME/EUPS_DESDM
cd $HOME/EUPS_DESDM

3) Install EUPS

Download the EUPS self-install script

curl -O http://desbuild.cosmology.illinois.edu/desdm_eupsinstall.py

After that, run it with python:

python desdm_eupsinstall.py

and follow the instructions.

If you get a message like: "On OSX only CLANG compilers are supported"

In another terminal type: xcodebuild -find clang

Similarily for: Please select the CLANG C++ compiler that will be used to build packages:

xcodebuild -find clang++

 

 

It will ask for two installation paths, one for EUPS itself and one for the software installed via EUPS packages. It will also ask if ICC and MKL should be used (which leads to a set of additional questions). The script can also modify the login-scripts to setup EUPS every time you log in. After confirming the settings the script will download and install EUPS.

In case we are re-installing EUPS, make sure we clean-up the EUPS variables.

unsetenv EUPS_PATH
unsetenv EUPS_DIR 

4) SVN Access

Make sure you have read access (check out) to DESDM Subversion repository.

svn info $SVNROOT

or something like:

svn --username "your username" info $SVNROOT 

or

svn --username desdmsvn info $SVNROOT [see below for password information]

Note that the SVNROOT environment variable is set by a setup script (e.g., eups/desdm_eups_setup.sh) in the directory where EUPS was installed. This script should be called automatically if you open a new terminal.

Subversion (SVN) access problems

If you forgot your password, it might be stored as plain text in your home directory space under:

$HOME/.subversion/auth/svn.simple/

You should also have received an email with your SVN password when you signed up for DESDM access. Since you are not allowed to change your SVN password, you should be able to search your email for a message like this:

SUBJECT: DES Subversion Access Information

BODY: 
   Hello <username>,

   Welcome to the Dark Energy Survey Subversion system.  The repository is located at:
   SVN URL: https://desweb.cosmology.illinois.edu/svn/desdm/devel

   Your username is: <username>
   Your password is: <password>

5) Start installing packages

For example, to install the development packages:

eups distrib install pythonCore spring2016+0 --nolocks

Once it build, you can load it like this:

setup -v pythonCore spring2016+0

Some example commands

Find all versions of Sextractor

eups distrib list   | grep sextractor

 

If you get an error like this:

eups distrib: Unable to take shared lock on /data/vault/rgm/soft/des/DESDM/eups/packages: an exclusive lock is held by [user=rgm, pid=17165]

Try this

eups distrib list sextractor

eups distrib list <package-name>

eups distrib list  --nolocks | grep sextractor

Install Sextractor

 

If you get an error like this:

eups distrib: Unable to take shared lock on /data/vault/rgm/soft/des/DESDM/eups/packages: an exclusive lock is held by [user=rgm, pid=17165]

Try this

eups distrib list sextractor

eups distrib list <package-name>

eups distrib list  --nolocks | grep sextractor

Install Sextractor

eups distrib install --nolock sextractor 2.21.0+1

setup -v sextractor 2.21.0+1
