# Makefile for GNU tar program.

SHELL = /bin/sh

# In order to disable remote-tape support, add -DNO_REMOTE to the
# appropriate DEFS line, and remove rtape_lib.* from LOCAL_{SRC,OBJ}
# For Ultrix 3.1, you will have to compile rtape_lib.c with -DUSG.
# Add -DUSE_REXEC to use rexec for remote tape operations
# instead of forking rsh or remsh.
#
# If tar fails to properly print error msgs, or core-dumps doing same,
# you may need to change which version of msg...() you are using.
# To do so, add one of the following to your DEFS= line
# -DSTDC_MSG		If you are using an ANSI compiler, and have vfprintf().
# -DVARARGS_MSG		If you have varargs.h and vfprintf()
# -DDOPRNT_MSG		If you have _doprnt(), and no useful varargs support
# -DLOSING_MSG		If nothing else works.
#
# Some non-BSD systems may have to add -DNEED_TZSET in order to have getdate.y
# compile correctly.
#
# If you have a system V system which defines size_t, add -DHAVE_SIZE_T.
# If you have a system which defines strstr, add -DHAVE_STRSTR.
#
# If you can't use remote tar with the rmt library, you can still get
# some stuff to work right by adding -DUSE_REXEC.
#
# Some people's systems define a prototype for signal handlers which
# require them to be declared as void.  If you get such problems in
# rtape_lib, function command, then define -DSIGNAL_VOID.  
#
# getdate.y has 8 shift/reduce conflicts.
#
# In addition to setting DEFS appropriately for your system, you might
# have to hand edit the #defines and #undefs in port.c.

# Minix "make" doesn't expand macros right, so Minix users will have
# to expand CFLAGS, SRCS, O, etc by hand, or fix your make.  Not my problem!
# You'll also need to come up with ctime(), the directory
# library, and a fixed doprintf() that handles %*s.  Put this stuff in
# the "SUBSRC/SUBOBJ" macro below if you didn't put it in your C library.
# Note that Minix "cc" produces ".s" files, not .o's, so O = s has been set.
