Unfortunately you do not tell us which version of ROOT and which OS you are using (could be 64-bit VMS and ROOT 0.99, for all I know).

But on "industry standard" RHEL/SL6.2, ROOT v5.32.03 cross-compiles just fine.

I do this:

1. setarch i386
2. build.sh (see below)

This usually fails until I install all missing/required 32-bit devel packages, an inclusive list is below: (it includes other random packages required in our environement, trim it as needed):

yum install --skip-broken giflib.i386 giflib.i686 giflib.x86_64 compat-libf2c-34.i386 compat-libf2c-34.i686 mysql-devel mysql-devel.i686 openssl-devel.i686 sysstat "libusb-devel*" unixODBC-devel unixODBC-devel.i686 postgresql-devel libxml2-devel libXpm-devel libgfortran libstdc++-devel.i386 libstdc++-devel.i686 git compat-readline43 "graphviz*" dcap "zlib-*.i686" "libXext-*.i686" "libXtst-*.i686" "tigervnc*" telnet glibc"*" glibc-static.i686 freetype.i686 fontconfig.i686 libpng.i686 libXrender.i686 strace "fftw*" libpng "freetype*" xpdf "xemacs*" tkcvs xterm mutt "*g77*" joe "libXmu*" glibc-devel.i686 libX11-devel.i686 libXpm-devel.i686 libXft-devel.i686 mysql-devel.i686 dcap-devel dcap-devel.i686 gsl-devel gsl-devel.i686 pcre-devel pcre-devel.i686 fontconfig-devel.i686 freetype-devel.i686 libpng-devel.i686 libjpeg-devel.i686 libgfortran.i686 libxml2-devel.i686 h5py

2) run build.sh again
