difx_db installs in a way that should be familiar to most that have installed modern Gnu software. Requirements: Package cx_oracle (available at http://cx-oracle.sourceforge.net/) is required. To install from a .tar.gz distribution: tar zxvf difx_db-XXX.tar.gz cd difx_db-XXX ./configure --prefix= (replace with the base install dir) make # (maybe become root here) make install To install from a fresh svn checkout, run the following: aclocal autoconf automake -a ./configure --prefix=${DIFX_PREFIX} make # (su root?) make install After an svn update, these steps do not need to be rerun. usually just "make" will update everything properly, but sometimes it is necessary to run "autoreconf" before compiling again. If that doesn't work, one can always fall back on the above sequence of commands.
