# Steps followed to build gt4gahp

Step - I
--------
Getting the gahp related files from GT

1. Download the gt3.9.5-all-source-installer.tar.gz from Globus website

2. Apply the patch gramjob which Jamie gave

3. Build GT4 gram using following 

./configure --prefix=$GLOBUS_LOCATION --enable-wsgram-condor

time make gpt globus_libtool globus_common globus_common_setup globus_core globus_data_conversion globus_callout globus_openssl globus_gsi_proxy_ssl globus_gsi_openssl_error globus_openssl_module globus_gsi_sysconfig globus_gsi_cert_utils globus_gsi_callback globus_gsi_credential globus_gsi_proxy_core globus_gssapi_gsi globus_gss_assist gssapi_error globus_xio globus_io globus_mp globus_nexus globus_duct_common globus_duct_control globus_rsl globus_rsl_assist globus_gram_protocol globus_gass_transfer globus_gass_server_ez globus_gram_client globus_duroc_common globus_duroc_control globus_gram_client_tools globus_proxy_utils globus_user_env wsjava globus_wsrf_mds_usefulrp_schema globus_wsrf_mds_usefulrp globus_ftp_control globus_ftp_client globus_libxml2 wsrft gt4-gram gt4-gram-condor globus_gram_job_manager postinstall

If some of the files required below are missing that are required in 
Step - III from $GLOBUS_LOCATION build GT4 using following command -

time make all

Step - II
---------

Getting the gt4-gahp.jar from condor source

1. Checkout the gt4 related stuff from the trunk

CVSROOT=:ext:parag@chopin.cs.wisc.edu:/p/condor/repository/CONDOR_SRC CVS_SERVER=/p/condor/public/bin/auth-cvs CVS_RSH=ssh cvs co src_java

2. cd src_java/gt4-gahp

3. ./build-gaph.sh
This will create the gt4-gahp.jar

Step - III
----------

Creating the gt4-gahp bundle

1. Create a directory gt4
   mkdir -p gt4/lib
   mkdir -p gt4/etc

2. Do the following copy 
   cp -r $GLOBUS_LOCATION/lib/*.jar gt4/lib
   cp -r $GLOBUS_LOCATION/etc/globus_delegation_service gt4/etc
   cp -r $GLOBUS_LOCATION/etc/globus_wsrf_common gt4/etc
   cp -r $GLOBUS_LOCATION/etc/globus_wsrf_core gt4/etc
   cp -r $GLOBUS_LOCATION/etc/globus_wsrf_core_registry gt4/etc
   cp -r $GLOBUS_LOCATION/etc/globus_wsrf_mds_usefulrp gt4/etc
   cp -r $GLOBUS_LOCATION/etc/globus_wsrf_rendezvous_service gt4/etc
   cp -r $GLOBUS_LOCATION/etc/globus_wsrf_rft gt4/etc
   cp -r $GLOBUS_LOCATION/etc/grid-info-gram-rsl-reporter.schema gt4/etc

3. Copy gt4-gahp.jar created above to gt4/lib

4. Copy $GLOBUS_LOCATION/share gt4
   share directory mayhave some symlinks. Do not copy the symlinks but 
   create a separate directory by itself for the symlinks else condor
   build fails on building the external on some RH platforms. This is a
   wierd behaviour from "cp -rL"

5. Copy other required files/directories from the GLOBUS_LOCATION

6. Tar the gt4 directory to form the gt4-gahp bundle

Step - IV
---------

Changes to condor_config/condor_configure

1. Add following lines to src/condor_examples/condor_config

GT4_GAHP = $(SBIN)/gt4_gahp
GT4_LOCATION = $(LIB)/gt4
GRIDFTP_URL_BASE = gsiftp://$(FULL_HOSTNAME)

Step - V
--------

Follow the instructions to "Add external to condor externals"
