# Makefile.swig.gen for @NAME@.i

## Default install locations for these files:
##
## Default location for the Python directory is:
##  ${prefix}/lib/python${python_version}/site-packages/[category]/@NAME@
## Default location for the Python exec directory is:
##  ${exec_prefix}/lib/python${python_version}/site-packages/[category]/@NAME@
##
## The following can be overloaded to change the install location, but
## this has to be done in the including Makefile.am -before-
## Makefile.swig is included.

@NAME@_pythondir_category ?= gnuradio/@NAME@
@NAME@_pylibdir_category ?= $(@NAME@_pythondir_category)
@NAME@_pythondir = $(pythondir)/$(@NAME@_pythondir_category)
@NAME@_pylibdir = $(pyexecdir)/$(@NAME@_pylibdir_category)

## SWIG headers are always installed into the same directory.

@NAME@_swigincludedir = $(swigincludedir)

## This is a template file for a "generated" Makefile addition (in
## this case, "Makefile.swig.gen").  By including the top-level
## Makefile.swig, this file will be used to generate the SWIG
## dependencies.  Assign the variable TOP_SWIG_FILES to be the list of
## 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).
##
## This code is setup to ensure parallel MAKE ("-j" or "-jN") does the
## right thing.  For more info, see <
## http://sources.redhat.com/automake/automake.html#Multiple-Outputs >

## Stamps used to ensure parallel make does the right thing.  These
## are removed by "make clean", but otherwise unused except during the
## parallel built.  These will not be included in a tarball, because
## the SWIG-generated files will be removed from the distribution.

## Entry rule for running SWIG

@NAME@.h @NAME@.py @NAME@.cc: @NAME@.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)/@NAME@-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.
##
	trap 'rm -rf $(DEPDIR)/@NAME@-generate-*' 1 2 13 15; \
##
## Create a temporary directory, which acts as a lock.  The first
## process to create the directory will succeed and issue the MAKE
## command to do the actual work, while all subsequent processes will
## fail -- leading them to wait for the first process to finish.

## execution will come back that the rule doesn't need to be executed

## will be positive.  Remove the the directory lock, which frees up
## any waiting process(es) to continue.

# KLUDGE: Force runtime include of a SWIG dependency file.  This is

# we have accurate dependencies for our swig stuff, which is good.
