View source for Earlier solgemc installation outside JLAB

by Rich Holmes

I have been working on getting the Geant4 simulation and related software up and running on a couple of non JLAB systems; here are some notes on what I did the first two times. I may be omitting some steps here and I definitely have rearranged the order and left out some steps that I tried but that didn't seem to give useful results, so there are no guarantees this will work for anyone else, but it should cut down on confusion, or so I hope. [[Solgemc installation outside JLAB|The later installation]] should be a better example to follow than my these (thanks to better understanding on my part, and probably some improvements in the solgemc package itself).

= Second and better installation =

The target system for now is one running Ubuntu 10.10 (32 bit i386).

Generally speaking what I tried to do was to set up a directory structure similar to what is installed using the gemc RPM; qt4 and geant4 already existed on this system but not necessarily configured as needed for gemc, so I put new installations into the new directory tree.

== initial setup ==
# mkdir ~/jlab_software ''and cd there''
# mkdir Linux_Ubuntu10.04-i686-gcc4.4.3

== environment ==
# svn checkout https://phys12svn.jlab.org/repos/trunk/ce ''in ~/jlab_software''
# ''Edit to set DEFAULT_JLAB_ROOT to ~/jlab_software. Also edit default software versions below that as needed.''
# ''Depending on your Linux distribution you may need to edit ce/osreleast.pl in the obvious place to set an appropriate value for $release. For my Ubuntu 10.10 installation this was not necessary.''
# source ~/jlab_software/ce/jlab.csh

== scons ==

# ''Install scons using Ubuntu Software Center''
# svn checkout https://clas12svn.jlab.org/repos/trunk/clas12/scons_scripts/ ''in ~/jlab_software''
# ''Depending on your ROOT version you may need to change''<br />env.Append(LIBPATH = [ROOTSYS + '/lib/root'])<br />''to''<br />env.Append(LIBPATH = [ROOTSYS + '/lib'])<br />''in loadroot.py''

== Qt4 ==
