# Package Makefile for the "Classic VM" Squeak Smalltalk system
# See http://squeak.org and http://squeakvm.org
#
# squeak uses cmake and a custom configure script (not GNU autoconf)
# in order to build this package, "cmake" must be installed
#
# squeak was built both in 32-bit and 64-bit mode
# but since 2023 version 4.20.6 now only in 64 bit per OpenIndiana request
# OpenIndiana is dropping 32bit libraries so we can't build 32bit any longer
#
# the squeak driver script was/is checking the Smalltalk image (using ckformat),
# and depending on whether the image is 32bit or 64bit,
# it launches the squeak virtual machine 32bit or 64bit for the image
#
# we now (since 4.20.6) try to use the 64bit executable to launch 32bit images
# and for 64bit images simply fail (with an error message)
#
# for 32-bit : ckformat reports 6505
# 6505: a 32-bit V3 image with closure support and float words stored 
# in native platform order
#
# for 64-bit : ckformat reports 68000
# 68000: a 64-bit V3 image with no closure support and 
# no native platform float word order requirement
#
# note that since 4.20.6 the 64bit images (68000) are no longer working
# but this is not much of a problem due to the fact that all images are 6502
# or 6504 (32bit)
#
# squeak places its 64-bit shared object files in
# usr/lib/squeak/<version>-<svnversion>_64bit/  with a _64bit suffix
# which is unfortunately not conforming to the usr/lib/amd64 usage
# and it generates a hard error by pkglint "64-bit object in 32-bit path"
# so we deliver a patch and rename files
# in order to put the 64-bit objects in their usual usr/lib/amd64 location

BUILD_BITS=64

# there is support for OpenSSL 1.1 and 3.x in the squeak SSL module
# but the SUnit squeak images tests seem to be written for old ssl versions
# this can be set before including shared-macros.mk
USE_OPENSSL10=yes

# the goal is to use libjpeg8-turbo but that links, but does not display
# working jpeg images; needs to be fixed upstream by the Squeak team
# currently use libjpeg6-ijg which is better than using the copy of
# those libjpeg files in the squeak source tree
