I should clarify my statements below. What build-xorg does is download
and build all of the sources for Xorg and all of its dependent
libraries, which takes a significant amount of time. build-xorg has two
modes: dynamic and static. The static mode (enabled by -static) allows
it to build a version of Xvnc that does not have any dynamic
dependencies on libX11, etc. This mode should work on any Linux
platform, and it is the way we generate our "official" project binaries.
The dynamic mode, however, is meant mainly for testing purposes and
probably won't work right on systems that already have recent Xorg
libraries-- build-xorg generates a version of Xvnc from an older Xorg
source base (7.4), but if it is dynamically linked, it will be
attempting to load the newer libX11, etc. from your system if they exist
(bad mojo ensues.) Plus, you really don't want or need to build all of
the dependencies of Xorg, because your system integrator was nice enough
to do that for you.
There is really no way for us to produce a "universal" script to do the
below, because it's all very system-specific. It should be the province
of system integrators to produce versions of TigerVNC that work with
their specific Xorg distributions. build-xorg is meant for testing on
systems that don't have Xorg (or don't have a recent enough version,
such as is the case for Red Hat Enterprise 4 and 5) or for building a
"cross-compatible" version of TigerVNC.
