# Slackware build script for syncterm

# 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). Though, if I add it to the dialing list, I
#    still can't make it work directly from the command line, even
#    though it works from the menu. *Shrug*.

# 20250123 bkw: update for v1.4.

# 20241203 bkw: update for v1.3.
# - patch for -current no longer needed (and no longer works anyway), removed.
# - 'make install' now installs the icons, stopping shipping our own.
# - manpage.diff reworked for 1.3.
# - remove -j1 from make: parallel builds work fine now.

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

# Man page: Fix path to dialing list and a couple typos. The path
# baked into the binary really is /etc/syncterm.lst (not /usr/etc)...
# In 1.3, the system dialing list actually works. If both the system
# and user lists both exist, both are read, which is nice.

# This is a big hassle: -O3 is hardcoded in a makefile... which is
# inside a zip file. To force our flags, we have to extract the zip
# 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.

# - INSTALL_DATA: install man page with usual Slackware permissions.
# - SRC_ROOT has to be set because the makefile is dumb...
