The confDEPEND_TYPE macro defines the method that
should be included in your Makefile for use in
creating make(1) dependencies. The methods
supported are located in the devtools/M4/depend
directory. We show them in Table 2-6.

Note that the correct Solaris method is usually chosen for you in an
appropriate devtools/OS file. But in the rare case that the method is
wrong or broken, you can use this confDEPEND_TYPE to select another
method. For example, consider this broken implementation of a mkdep
script:
mkdep -a -f Makefile -I. -DNEWDB *.c
cc: Warning: Option -f passed to ld
cc: Warning: File with unknown suffix (Makefile) passed to ld
In this example, we know we are running X11, and so we chose to
replace the defective mkdep with the
makedepend(1) program:
define(`confDEPEND_TYPE', `X11')
The new method is specified as the filename (with the
.m4 suffix removed) in the
devtools/M4/depend directory. Rerunning the
Build with -c and this new
definition will produce error-free output:
Making dependencies in obj.SunOS.4.1.3.sun4
makedepend -- -I. -I/usr/local/include/db -DNEWDB -DNEWDB -DMATCHGECOS=0 -- *.c
