171. Building ECCE on ROCKS/CentOS

I installed ECCE on a couple of a single workstation with ROCKS, and remotely on a 40 core cluster with ROCKS. The local, workstation install worked fine. I never really bothered much about the cluster install, and only recently looked closer at it. Well, I can launch the 'gateway' but nothing else -- when I click on e.g. the organizer button I get the rocks version of an hourglass that never goes away -- and I don't get any error messages. Turning on logging doesn't yield anything either. 

Ergo, I figured that building it myself  may yield a different result. It didn't on the ROCKS cluster, but everything worked just fine on the single-node ROCKS training box I keep in my office.

CentOS is a bit dated, so you'll need to build your own apr and apr-util. Build apr:
cd /share/apps/utils/
wget http://mirror.mel.bkb.net.au/pub/apache//apr/apr-1.4.6.tar.gz
wget http://mirror.mel.bkb.net.au/pub/apache//apr/apr-util-1.4.1.tar.gz
tar xvf apr-1.4.6.tar.gz
cd apr-1.4.6/
./configure --prefix=/share/apps/utils/apr
make install
cd ../
tar xvf apr-util-1.4.1.tar.gz
cd apr-util-1.4.1/
./configure --prefix=/share/apps/utils/apr-util --with-apr=/share/apps/utils/apr/

Time for ecce.
First download 
cd /share/apps/ecce/
tar xvf ecce-v6.3-src.tar.bz2
cd ecce-v6.3/
export ECCE_HOME=/share/apps/ecce/ecce-v6.3
cd build/

Edit build_ecce
889       ./configure --prefix=$ECCE_HOME/${ECCE_SYSDIR}3rdparty/httpd --enable-rewrite --enable-dav --enable-ss-compression
889       ./configure --prefix=$ECCE_HOME/${ECCE_SYSDIR}3rdparty/httpd --enable-rewrite --enable-dav --enable-ss-compression --with-apr=/share/apps/utils/apr/bin/apr-1-config --with-apr-util=/share/apps/utils/apr-util/bin/apu-1-config

Just follow the instructions i.e. hit return, over and over again. Answer no to running tests again. Then run build_ecce again:
Now stuff should be building. Do this another six times. From the README:
"At this stage the script will build one 3rd party package per invocation,
exiting after each package is built.  In order the 3rd party packages that
will be built are:
1. Apache Xerces XML parser
2. Mesa OpenGL
3. wxWidgets C++ GUI toolkit
4. wxPython GUI toolkit
5. Apache HTTP web server"
The httpd build ends with a minor error about "lib" missing. It's fine.

The sixth time ECCE itself is built, and that's the step that takes by far the longest. It finishes with:
 ECCE built and distribution created in /share/apps/ecce/ecce-v6.3
On a single-node desktop I got it to run a seventh time it seemed. The last step finished with the message above though.

Go to your /share/apps/ecce/ecce-v6.3/ dir where you'll find install_ecce.v6.3.csh
Do the install
csh -f install_ecce.v6.3.csh
Follow the instructions.

You may also want to
sudo mv /etc/csh.* ~/
to get rid of the crappy csh config files.

Edit your ~/.bashrc:

alias startecceserver='csh -f /share/apps/ecce/ecce-v6.3/server/ecce-admin/start_ecce_server'
alias stopecceserver='csh -f /share/apps/ecce/ecce-v6.3/server/ecce-admin/stop_ecce_server
export ECCE_HOME=/share/apps/ecce/ecce-v6.3/apps
export PATH=$PATH:${ECCE_HOME}/scripts

and your ~/.cshrc:

setenv ECCE_HOME /share/apps/ecce/ecce-v6.3/apps
set PATH= (/share/apps/nwchem/nwchem-6.1/bin/LINUX64 $PATH)

On my single-node box I had to edit the apps/siteconfig/DataServers and replace eccetera.emsl.pnl.gov with localhost (two instances), as well as the apps/siteconfig/jndi.properties file (one instance).

In spite of the hassle on the single node box, everything works there -- the builder, organizer etc. all open just fine. The rocks cluster, looks fine, but doesn't work.

The ROCKS Cluster:
Everything seems to work fine -- starting ecce launches the gateway, but clicking on anything sees the centos version of the hourglass churn over and over for all eternity. Nothing happens.

I looked through these two threads, and i also tried the pre-built 32 bit binary. All without luck.

I've also tried editing the site_runtime file:
ECCE_MESA_EXCEPT x86_64:RedHat:Fedora:CentOS
(matches the lsb_release -is output)
