# Slackware build script for ft2demos
# Written by B. Watson (urchlay@slackware.uk)
# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# This thing requires first building (but not installing) freetype2,
# hence all the downloads.
# This script is heavily based on Pat Volkerding's freetype.SlackBuild:
# https://slackware.uk/slackware/slackware-14.2/patches/source/freetype/
# ...and Arch Linux's freetype2-demos PKGBUILD:
# https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/freetype2
# Note to self: keep VERSION in sync with Pat's patches/freetype.
# 20211208 bkw: updated for v2.11.1.

### Now, build ft2demos. These will end up dynamically linked to the
# system libfreetype.so after package installation, *except* for
# ftvalid, which won't work with Slackware's libfreetype.so, so it
# gets statically linked with the libfreetype.a we just built. See
# DIRTY_HACK, parts 1 and 2.

sed -i '/^ *# *EXES/s|# *||' Makefile
# Don't try to build ftvalid yet. If we do, the resulting binary is
# useless, complains that none of its validation methods are compiled in,
# and suggests rebuilding FreeType.

# build we just did.

# DIRTY_HACK, part 2. Get the link command libtool generated for ftvalid,
# and replace freetype.so with freetype.a (the static lib). This is me
# working around libtool's "helpful" automation. Die, libtool!
