#; Adapted from makefiles for IHS and data-structures library, which were
#; created by Bishop Brock.

#; NOTE:  Target "all" causes a recursive invocation of make with ACL2 set to
#; its current value.  These recursive invocations of make thus have ACL2 set
#; on the command line, which overrides any values of ACL2 set in those files.
#; This should not cause any problems unless you try to do something fancy; see
#; the comment for example just above target .exercises.cert in
#; books/case-studies/ivy/ivy-v2/ivy-sources/Makefile from the ACL2
#; distribution.

# Success can be determined by checking for the absence of ** in the log.

#################### Editable variables ####################

# The ACL2 macro defines how to run ACL2.  The default command below prints
# runtime statistics for the certification, and runs it `nice' in an attempt to
# lessen interference with interactive jobs.  We normally inhibit most output
# during certification to speed up the proofs.  Edit as necessary.  The setting
# below reflects an assumption regarding where this makefile will be executed,
# namely, directly under books/.  This assumption can of course be overridden
# by specifying ACL2=acl2 (or change acl2 to your saved image) on the command
# line.

ACL2 = time nice ../../saved_acl2

# Fix problem with sh on some Linux systems:
ifeq ($(OSTYPE),linux)
	SHELL = bash
	ACL2 = ../../saved_acl2
endif
ifeq ($(OSTYPE),linux-gnu)
	SHELL = bash
	ACL2 = ../../saved_acl2
endif

# Inhibit all output except the summary (which can be useful for tracking down problems).
# Set this to "" if you do want the output.

INHIBIT = (assign inhibit-output-lst (list (quote prove) (quote proof-tree) (quote warning) (quote observation) (quote event)))

# Support for make dependencies:  should be a list of book names without
# the .lisp suffix.  Can be overridden on the command line or in a file
# that includes this file.

BOOKS = $(patsubst %.lisp, %, $(wildcard *.lisp))
