# Slackware build script for syncterm

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Issues:
# 1. Figure out why shell: doesn't work on the command line (though
#    it does, with the ^D "quick connect" option, or by adding it to
#    the dialing list).
# 2. How do we use /etc/syncterm.lst? strace shows that syncterm reads it,
#    but entries there don't show up in the dialing list (not even if there's
#    no user list). If I could get the system list to work, I'd include an
#    entry there for a local shell (to work around issue #1). But probably
#    nobody much cares about using this as an xterm or konsole replacement...
# Neither of these issues are going to prevent me from submitting this.

# Note: phigan on #atari tells me they're "almost ready" to release 1.2,
# so this may get updated soon.

# 20240218 bkw: BUILD=2
# - add compile fix for -current.

# This is a big hassle: -O3 is hardcoded in a makefile... which is

# file, mod the makefile, then re-zip it. Using -0 with zip means
# "store" (for speed).

# Lots of make options here:
# - RELEASE=1 means binary already stripped, man page already gzipped.
# - WITHOUT_PORTAUDIO=1 to avoid a hidden dependency on portaudio. I
#   see no advantage to using portaudio anyway (SDL audio works fine).
# - INSTALL_DATA: install man page with usual Slackware permissions.
# - SRC_ROOT has to be set because the makefile is dumb...
# - Use -j1 as the compile always fails if -jN where N>1.
