(make.info)Complex Makefile
Complex Makefile Example
************************
Here is the makefile for the GNU `tar' program. This is a
moderately complex makefile.
Because it is the first target, the default goal is `all'. An
interesting feature of this makefile is that `testpad.h' is a source
file automatically created by the `testpad' program, itself compiled
from `testpad.c'.
If you type `make' or `make all', then `make' creates the `tar'
executable, the `rmt' daemon that provides remote tape access, and the
`tar.info' Info file.
If you type `make install', then `make' not only creates `tar',
`rmt', and `tar.info', but also installs them.
If you type `make clean', then `make' removes the `.o' files, and
the `tar', `rmt', `testpad', `testpad.h', and `core' files.
If you type `make distclean', then `make' not only removes the same
files as does `make clean' but also the `TAGS', `Makefile', and
`config.status' files. (Although it is not evident, this makefile (and
`config.status') is generated by the user with the `configure' program,
which is provided in the `tar' distribution, but is not shown here.)
If you type `make realclean', then `make' removes the same files as
does `make distclean' and also removes the Info files generated from
`tar.texinfo'.
In addition, there are targets `shar' and `dist' that create
distribution kits.

# Things you might add to DEFS:

# -DPOSIX If you have POSIX.1 headers and

# -DBSD42 If you have sys/dir.h (unless
# you use -DPOSIX), sys/file.h,
# and st_blocks in `struct stat'.
# -DUSG If you have System V/ANSI C
# string and memory functions
# and headers, sys/sysmacros.h,
# fcntl.h, getcwd, no valloc,
# and ndir.h (unless
# you use -DDIRENT).
# -DNO_MEMORY_H If USG or STDC_HEADERS but do not

# -DDIRENT If USG and you have dirent.h
# instead of ndir.h.
# -DSIGTYPE=int If your signal handlers
# return int, not void.
# -DNO_MTIO If you lack sys/mtio.h
# (magtape ioctls).
# -DNO_REMOTE If you do not have a remote shell
# or rexec.
# -DUSE_REXEC To use rexec for remote tape
# operations instead of
# forking rsh or remsh.
# -DVPRINTF_MISSING If you lack vprintf function
# (but have _doprnt).
# -DDOPRNT_MISSING If you lack _doprnt function.
# Also need to define
# -DVPRINTF_MISSING.
# -DFTIME_MISSING If you lack ftime system call.
# -DSTRSTR_MISSING If you lack strstr function.
# -DVALLOC_MISSING If you lack valloc function.
# -DMKDIR_MISSING If you lack mkdir and
# rmdir system calls.
# -DRENAME_MISSING If you lack rename system call.
# -DFTRUNCATE_MISSING If you lack ftruncate
# system call.
# -DV7 On Version 7 Unix (not
# tested in a long time).
# -DEMUL_OPEN3 If you lack a 3-argument version
# of open, and want to emulate it
# with system calls you do have.
# -DNO_OPEN3 If you lack the 3-argument open
# and want to disable the tar -k
# option instead of emulating open.
# -DXENIX If you have sys/inode.h
# and need it 94 to be included.
