A generic makefile skeleton for Icon programs by Bob Alexander:

-------------------------------------------------------------------------
#
#  Makefile for Icon Programming Language program:
#
PROGRAM=|>Program Name<|

#
#  To customize this file, usually only the definitions of macros
#  PROGRAM and FILES require modification.
#

#
#  Specification of separate files that make up the program.
#
#  Note that the .u1 suffix is used here; the corresponding .icn files
#  are automatically identified by the implicit rule.
#
FILES=|>List of component files, space separated, using .u1 suffix<|

#
#  Option flag definitions, etc.
#
ICFLAGS=-s
IFLAGS=-s
ICONT=icont

#
#  Implicit rule for making ucode files.
#
.SUFFIXES: .u1 .icn
.icn.u1:
	$(ICONT) -c $(ICFLAGS) $*

#
#  Explicit rules for making an Icon program.
#
all:	$(PROGRAM)

$(PROGRAM): $(FILES)
	$(ICONT) -o $(PROGRAM) $(IFLAGS) $(FILES)
