2) Changed Makedepend system to make individual dependency files, which should save time rebuilding dependencies by limiting the regeneration of dependency file for only modified source files.

# Ok.. If you are looking hard at the following lines of gnarled code, you
|
|
# deserve an explanation. This target makes a link from the installed
|
|
# directories (Assumed to be rooted at $(TOPDIR), usually $(TOPDIR)/bin or
|
|
# $(TOPDIR)/lib) to a just-built target. Both LNSRC (Link source) and LNDEST
|
|
# (Link destination) must be defined before calling 'make __link'.
|
|
#
|
|
# The first four lines check to see that both LNSRC and LNDEST have been
|
|
# defined.
|
|
#
|
|
# The (very long) following 'if' statement reads in pseudo-code like this:
|
|
#
|
|
# if the current link is not pointing to the intended destination
|
|
# then
|
|
# announce (echo) intentions to reset link
|
|
# compute the link path by the following steps
|
|
# a) define SRCDIR as the current absolute directory
|
|
# appended by the directory of the intended source of the link
|
|
# b) define DESTDIR as the absolute path of $(TOPDIR) appended by
|
|
# the directory of the intended destination of the link
|
|
# c) define a temproary variable T to be the absolute path of
|
|
# the destination directory less the prefix of the absolute
|
|
# path of $(TOPDIR)
|
|
# e.g. /root/work/thisdir/bin/ - /root/work/thisdir/ = bin/
|
|
# d) Run a loop, truncating the path represented by T until
|
|
# 'dirname' returns '.'. On each iteration increment PFX
|
|
# (Prefix) by '../' This will define the prefix for the path
|
|
# of the link.
|
|
# e.g. If DESTDIR is lib/osgPlugins, PFX is ../../
|
|
# e) Define the link as a concatenation of PFX and the absolute
|
|
# path of the source directory less the absolute path of
|
|
# $(TOPDIR)
|
|
#
|
|
# Change directories in to the link destination directory
|
|
# run the link command
|
