# CKUBS2.MAK, Thu Aug 22 18:32:45 1996
#
CKVER= "6.0.192 Beta.029"
#
# Abbreviated version for 2.10 / 2.11 BSD, which chokes on full-size makefile
# because "Make: out of memory".
#
# Instructions:
#   1. Make sure there are no other files called "makefile" or "Makefile"
#      in the same directory.
#   2. Change the name of this file to "makefile".
#   3. Read below about the strings file.
#   4. "make bsd211"
#   5. If you are not on a system with /usr/lib/ctimed (2.10BSD for example),
#      type "make bsd210" (which will compile cku2tm.c into 'ctimed')
#      and then install 'ctimed' in the right place (default is /usr/lib).
#   6. 2.11BSD includes ctimed and the necessary stub routines.  The 'ctimed'
#      path is in <paths.h>.  The "libstubs.a" (obtained via a "-lstubs" at link
#      time) contains the stub routines.
#
# Authors: Frank da Cruz, Columbia University, fdc@columbia.edu,
# and Steven M Schultz, sms@wlv.iipo.gtegsc.com.
#
# Modified 4 July 1992 to reshuffle overlays (because the first one got too
#   big) and to improve the method of defining the string file.  fdc.
# And again 23 Aug 1992.  fdc.
# And again 06 Sep 1992 to work around ckudia.c blowing up optimizers.  sms.
# And again 09 Sep 1992 to incorporate cku2tm.c and new ckustr.c.  sms.
# & again 19 Sep 92 to add -DMINIDIAL to reduce size of DIAL module.  fdc.
# & again 7 Nov 92 because two of the segments got too big.  fdc.
# & again 15-18 Apr 94, ditto, fdc.
# + again 11-13 Jun 96, for version 6.0.192, fdc.
# 18 Jul 96 to incorporate new 'ctimed' and stubs, sms.
# 22 Aug 96 to reshuffle overlays, fdc.

#
# 2.10BSD and 2.11BSD (the latter to a larger extent) are the same as 4.3BSD
# but without a large address space.
#
# A string extraction method is used to put approx. 16KB of strings into a
# file.  The module ckustr.c needs to find this file when C-Kermit runs.
# The pathname where this file will reside is defined below (change it if
# necessary).  After make is finished, the file cku192.sr must be moved to
# where ckustr.c has been told to look for it, or you can define an
# environment variable KSTR to override the built-in pathname, for example:
#
#  setenv KSTR `pwd`/cku192.sr
#
# If the resulting wermit program sprews garbage all over your screen, it's
# because it is reading the wrong strings file.
#
# If the resulting wermit program doesn't run at all because UNIX says it
# is too big, it's most likely because the data segment, the root segment,
# or one of the overlays is too big.  The sum of the data (mostly strings.o)
# and bss (mostly static buffers) sizes must be less than about 52K (56K is
# the maximum, but about 4K is needed for stdio buffers that are added in at
# runtime).  If the comibed data+bss size exceeds 52K, start chopping away
# at static buffers.  When it is borderline (> 52K but < 56K), performance
# will be terrible -- screen output will be very slow and jerky because
# stdio functions are doing a system call per character because they could
# not allocate any buffers.
#
# The maximum number of overlays is 15, but the fewer overlays, the better
# the peformance.  The smaller the root segment, the bigger the overlays can
# be:
# 
#   Root   Overlay
#   56KB     8KB
#   48KB    16KB
#   40KB    24KB  <--  This arrangement used in 6.0.192
#   32KB    32KB
#   24KB    40KB
#   16KB    48KB
#    8KB    56KB
#
# The hardest-hit modules should go into the root segment, so top priority
# goes to ckutio and ckufio, the low-level i/o modules.  It would also be
# good to put ckcpro and ckucmd in the root segment but they are too big.
#
# Here is the layout for 6.0.192:
#
# % size wermit
# text    data    bss     dec     hex
# 34368   25574   26414   86356   15154   total text: 126912
#         overlays: 23936,24512,23872,20224
#
# This shows root segment text is less than 40K,
# data+bss is less than 52K, and each overlay is less than 24K.

# Compile and Link variables:
#
# EXT is the extension (file type) for object files, normally o.
# EFLAGS is the CFLAGS _without_ the optimize flag (that is added separately).
#  The optimizer can not handle a couple modules (ckcpro.c and ckudia.c).
#  Sometimes this happens silently -- it just dies.
#  In that case there might be a message like:
#    Fatal error in /lib/c2 (which is the optimizer)
#    mv: x.o: Cannot access: No such file or directory
# NOTE: You can't add any more -D's to these because there is already
#  the maximum number of them.  See ckcker.h and ckucmd.h for additional
#  PDP-11 feature disabling.
