# Slackware build script for td_lib

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

# For a long time, this was bundled with ded. However, recent versions
# of ded have configure scripts and makefiles that have grown too
# complex to easily force it to find td_lib in a custom directory. The
# path of least resistance is to break this library out into its own
# build, even though nothing else besides ded uses it.

# 20240423 bkw, BUILD=2: add missing .pc file to package. I thought
# ded was compiling OK without it, but it was actually pulling in
# td_lib from $TMP, not the installed package... which meant building
# td_lib followed by ded seemed to work, but building td_lib, then "rm
# -rf /tmp/SBo", *then* building ded would fail. Grr.
