This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
CUnit is a lightweight system for writing, administering, and running
unit tests in C. It provides C programmers a basic testing
functionality with a flexible variety of user interfaces.
CUnit is built as a static library which is linked with the user's
testing code. It uses a simple framework for building test
structures, and provides a rich set of assertions for testing common
data types. In addition, several different interfaces are provided
for running tests and reporting results. These interfaces currently
include:
Automated Output to xml file Non-interactive
Basic Flexible programming interface Non-interactive
Console Console interface (ansi C) Interactive
Curses Graphical interface (Unix) Interactive
