Requirements

Please make sure to follow the instructions for compiling python prior to building ROOT since ROOT needs to be built against python.  ROOT may also be built against MySQL on the linuxes.  Also note that often the version of the source we utilize for ROOT is Fermi-specific where patches have been applied or the version of ROOT is from a branch from their Subversion repository.

Includes patch to TMVA Config.h and Config.cxx for windows

redhat5-i686-32bit-gcc41

Need fftw3, gccxml, GSL to be build.  Obtain FFTW 3.1.2 from:  http://www.fftw.org/download.html^{Image Added}
Build on rhel5-32 or bldlnx09:  ./configure --enable-portable-binary --enable-shared --prefix=$PWD

redhat4-i686-32bit-gcc34

1. Obtain Fermi's copy of the source from /afs/slac/g/glast/ground/GLAST_EXT/srcExtlibs/root-v5.26.00a-gl1.src..tar.gz and unpack, it will be dumped into a directory named "root"
2. set ROOTSYS to the same directory as the source was checked out into.  cd into the root directory
3. Run configure:
   ./configure linux --fail-on-missing --enable-mysql --with-mysql-incdir=/afs/slac/g/glast/ground/GLAST_EXT/redhat4-i686-32bit-gcc34/mysql/5.1.39/gcc34/include/mysql --with-mysql-libdir=/afs/slac/g/glast/ground/GLAST_EXT/redhat4-i686-32bit-gcc34/mysql/5.1.39/gcc34/lib/mysql --enable-xrootd --enable-python --with-python-incdir=/afs/slac/g/glast/ground/GLAST_EXT/redhat4-i686-32bit-gcc34/python/2.5.1-gl1/gcc34/include/python2.5 --with-python-libdir=/afs/slac/g/glast/ground/GLAST_EXT/redhat4-i686-32bit-gcc34/python/2.5.1-gl1/gcc34/lib/python2.5/config --enable-reflex --enable-cintex --enable-roofit --with-oracle-incdir=/usr/oracle/rdbms/public --with-oracle-libdir=/usr/oracle/lib --enable-minuit2 --enable-unuran --enable-table --enable-explicitlink --with-gccxml=$userSpace/root-v5.26-gl1/gccxml/0.9.0_20090601/slc4_ia32_gcc34/bin --enable-gdml --enable-genvector --enable-mathcore --enable-mathmore --with-fftw3-incdir=$userSpace/root-v5.26-gl1/fftw3/3.1.2/slc4_ia32_gcc34/include --with-fftw3-libdir=$userSpace/root-v5.26-gl1/fftw3/3.1.2/slc4_ia32_gcc34/lib --with-gsl-incdir=$userSpace/root-v5.26-gl1/GSL/1.10/slc4_ia32_gcc34/include --with-gsl-libdir=$userSpace/root-v5.26-gl1/GSL/1.10/slc4_ia32_gcc34/lib  > & config-rhel4.log &
4. Build by running "make >& build-rhel4.log &"
5. Update etc/system.rootrc to include the lines:
   # As suggested by Wilko, April, 2009, so that when a job writes to xrootd, missing directories are created upon request.
   XNet.Mkpath: 1
6. Copy the following into $GLAST_EXT using the directory structure:
   ROOT/v5.26.00a-gl1/gcc34/
   README bin build-rhel4.log cint config-rhel4.log doc etc fonts icons include lib macros man test tutorials
