Doozer is a cross-platform build system used for compiling
and linking 3D graphics applications including, but not
limited to, those written using
VR Juggler on the VRAC
workstations and PCs. It is named after the characters on the
television show Fraggle Rock who were constantly
building structures that the Fraggles subsequently ate. The
underlying architecture is built upon the
GNU version of the well-known
make utility. (Note that Doozer requires GNU make
version 3.78.1 or newer. This is the version installed on the
VRAC IRIX workstations.) Because it is based on this version
of make, the makefiles can be used on any platform supported
by GNU make.
Doozer was designed by
Patrick Hartling
and Kevin Meinert
in June 2000 in response to the typical VRAC programmer's
growing need for a common VR Juggler application build system.
In particular, the creation of the Performer Switcher
application brought that need to a head as it became obvious
that trying to combine the applications of several distinct
projects into one encompassing program would be far too
difficult without a common build system. It was also clear
that too many people were copying makefiles from the Juggler
sample programs and trying to adapt them to their own needs.
It has since been generalized so that it is useful for
applications that are not based on VR Juggler.
Thus, the primary design goal was to offload the complexities
of writing makefiles from the users who could better spend
their time writing their applications. By using Doozer, a
programmer can simply provide settings for several variables
that Doozer then uses to compile the application binary. The
aspects of the makefiles that are repeated over and over are
hidden inside Doozer while the unique factors are left up to
the programmer to complete.
