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 most recently. This is a much better example to follow than my previous ones, but you can read about those too if you want.

The target system is one running CentOS 6.3 (64 bit). Earlier I installed under Ubuntu 10.10 (32 bit i386) similarly.

I followed the procedure here to install gemc.

After that:

1. cd $JLAB_SOFTWARE/evio
2. Edit $JLAB_SOFTWARE/evio/SConstruct: add the following lines after env.Append(LIBPATH = ['lib']):

   
   env.Append(LINKFLAGS = '-fPIC')
   env.Append(CPPFLAGS = '-fPIC')
   env.Append(CXXFLAGS = '-fPIC')
   env.Append(CCFLAGS = '-fPIC')

3. scons -c; scons
4. cd $JLAB_SOFTWARE/gemc
5. Edit $JLAB_SOFTWARE/gemc/SConstruct: copy the env.Library line at the end, paste, and replace env.Library with env.SharedLibrary; also add the following lines after env.Append(LIBPATH = ['lib']):

   
   env.Append(LINKFLAGS = '-fPIC')
   env.Append(CPPFLAGS = '-fPIC')
   env.Append(CXXFLAGS = '-fPIC')
   env.Append(CCFLAGS = '-fPIC')

6. scons -c; scons

(The '-fPIC' edits were not needed for Ubuntu 10.10.)

solgemc

1. svn checkout https://jlabsvn.jlab.org/svnroot/solid/solgemc into $JLAB_SOFTWARE/solgemc and cd there
2. scons
3. In your ~/.cshrc add $JLAB_SOFTWARE/gemc to LD_LIBRARY_PATH environment variable
