There are two make utilities available in the Solaris 7 operating environment. The default version, /usr/ccs/bin/make, is identical to the SunOS release 4 make command. The SVR4 version is available in /usr/ccs/lib/svr4-make.
Using the default version, your Makefiles will not need changes. However, some of the commands used in your Makefiles may have changed. For example, install(1), commonly used in Makefiles, could produce unexpected results because of changes to the options, as shown in the following examples.
In a SunOS release 4 Makefile - install:
install -o bin -g bin -m 444 target.c /usr/bin/target
In a SunOS release 5.7 Makefile - install:
install -u bin -g bin -m 444 target.c /usr/bin/target
The version of install(1B) in /usr/ueb is compatible with the SunOS release 4 version.
Check the compatibility tables in Appendix A, Commands Reference Table, for information about individual interfaces.
