Using makefiles

Describes how to define program construction rules in makefiles.

Most UNIX™ platforms provide the make utility program to compile projects. The make program is an interpreter of makefiles. These files contain directives to compile and link programs and/or generate other kind of files.

When developing on Microsoft™ Windows® platforms, you may use the NMAKE utility provided with Visual C++. However, this tool does not have the same behavior as the UNIX make program. To have a compatible make on Windows, you can install a GNU make or third party UNIX tools such as Cygwin.

For more details about the make utility, see the platform-specific documentation.

File makeincl with generic makefile rules to be included in other Makefiles:

.SUFFIXES: .42s .42f .42m .42r .str .per .4gl .msg .hlp

FGLFORM=fglform -M
FGLCOMP=fglcomp -M
FGLMKMSG=fglmkmsg
FGLMKSTR=fglmkstr

all::
.msg.hlp:
        $(FGLMKMSG) $*.msg $*.hlp
.str.42s:
        $(FGLMKSTR) $*.str $*.42s
.per.42f:
        $(FGLFORM) $*.per
.4gl.42m:
        $(FGLCOMP) $*.4gl

clean::
        rm -f *.hlp *.42? *.out

include makeincl

FORMS=\
 customers.42f\
 orderlist.42f\
 itemlist.42f

MODULES=\
 customer_mgmt.42m\
 zoom_orders.42m\
 zoom_items.42m

all:: $(FORMS) $(MODULES)

In this example, the customer_mgmt module imports zoom_orders and zoom_items modules.
