Name
confDEPEND_TYPE
Synopsis
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 ...
