## Entry rule for running SWIG
|
|
|
|
usrp_prims.h usrp_prims.py usrp_prims_python.cc: usrp_prims.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)/usrp_prims-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.
