## this case, "Makefile.swig.gen"). By including the top-level
## Makefile.swig, this file will be used to generate the SWIG

## SWIG .i files to generated wrappings for; there can be more than 1
## so long as the names are unique (no sorting is done on the
## TOP_SWIG_FILES list). This file explicitly assumes that a SWIG .i
## file will generate .cc, .py, and possibly .h files -- meaning that
## all of these files will have the same base name (that provided for
## the SWIG .i file).

## Entry rule for running SWIG
audio_oss.h audio_oss.py audio_oss.cc: audio_oss.i
## This rule will get called only when MAKE decides that one of the
## targets needs to be created or re-created, because:
##
## * The .i file is newer than any or all of the generated files;
##
## * Any or all of the .cc, .h, or .py files does not exist and is
## needed (in the case this file is not needed, the rule for it is
## ignored); or
##
## * Some SWIG-based dependecy of the .cc file isn't met and hence the
## .cc file needs be be regenerated. Explanation: Because MAKE
## knows how to handle dependencies for .cc files (regardless of
## their name or extension), then the .cc file is used as a target
## instead of the .i file -- but with the dependencies of the .i
## file. It is this last reason why the line:
##
## if test -f $@; then :; else
##
## cannot be used in this case: If a .i file dependecy is not met,
## then the .cc file needs to be rebuilt. But if the stamp is newer
## than the .cc file, and the .cc file exists, then in the original
## version (with the 'test' above) the internal MAKE call will not
## be issued and hence the .cc file will not be rebuilt.
##
## Once execution gets to here, it should always proceed no matter the
## state of a stamp (as discussed in link above). The
## $(DEPDIR)/audio_oss-generate stuff is used to allow for parallel
## builds to "do the right thing". The stamp has no relationship with
## either the target files or dependency file; it is used solely for
## the protection of multiple builds during a given call to MAKE.
##
## Catch signals SIGHUP (1), SIGINT (2), SIGPIPE (13), and SIGTERM
## (15). At a caught signal, the quoted command will be issued before
## exiting. In this case, remove any stamp, whether temporary of not.
## The trap is valid until the process exits; the process includes all
## commands appended via "\"s.
