If a date type were added to the report language, it would be possible
to distinguish fully-parsed dates in the report language (so invalid or
illegal dates could be flagged and handled separately in a report). The
date module already implements a date type internally, and it is
exposed to the rest of the program (gdate and gdate_val, which correspond
to GEDCOM date types), but not to the report language.

Of course you need a C Compiler and make, but also a number of other tools
like autoconf, automake, byacc and flex.
One way to build the code is to make a subdirectory, lets say called bld
in your lifelines directory, (where the toplevel Makefile.am is located)
and then build all the code there. This keeps the objects and executables
out of the source directories. This is the process shown here.

entitled "Building RPM packages as a non-root user." These were found
at http://www.rpm.org/hintskinks/buildtree. At that url was also a
tarball that included the files README( the note), .rpmrc and .rpmmacros.
The later two files are installed in your home directory. These do alter
the default behavior of rpm for you and are not required to build the rpm,
however, these instructions will fail.

In your ~/.rpmmacros file. It is used to put the name and email address
of the individual generating the rpm package into the file. Be sure to
use your name and email address. If there is a "Packager:" entry in the
lifelines.spec file, make sure it is correct, as it overrides the value
in your .rpmmacros file.
