# Slackware build script for qiv

# Modified & now maintained by B. Watson <urchlay@slackware.uk>. Original
# version had no license, modified version released under the WTFPL. See
# http://www.wtfpl.net/txt/copying/ for details.

# 20250627 bkw: update for v3.0.2. I have no idea why my last update
# was for 3.0.1 (3.0.2 was already out, I looked right at it and
# didn't see it somehow).

# 20250616 bkw:
# - Update for v3.0.1. The 3.x series no longer requires imlib2.
#   The new_formats.diff patch had to be reworked, so old versions
#   won't build. README rewritten, requirements for various image
#   formats have changed a bit.

# 20250328 bkw:
# - Update for v2.3.4. This is a release on upstream's codeberg page,
#   but the homepage hasn't been updated yet. codeberg's URLs are
#   "unstable" due to content-disposition, so the script has to
#   handle 2 possible filenames.

# 20241228 bkw: BUILD=2
# - support AVIF images. libheif handles them, just have to add the
#   filename extension and magic to main.h (in new_formats.diff).
# - mention libheif as an optional dep in README.
# - update qiv-allfmt.sqf to include libheif and its deps.

# 20230605 bkw:
# - Update for v2.3.3.
# - JPEG 2000 works now, so enable it in the Makefile.
# - WMF is broken. Fixed by adding new libwmf-type1-fonts optional
#   dep. Documented in README.
# - Rework new_formats.diff. Script can no longer build old version.
# - Fix and update qiv-allfmt.sqf.

# 20191231 bkw:
# - Add libopenraw (raw camera image) formats, BUILD=2.
# - Remove mention of wmf-pixbuf loader from README and .sqf
#   since there's a Slackware update that removes the need for it.

# 20191226 bkw:
# - Upgrade for v2.3.2. This was released a month after my last update,
#   but the download page on the site doesn't link to it (found it just
#   now by editing the URL for v2.3.1), so my update-checker script
#   never saw it...
# - As compensation for my tardiness, add support for a bunch of new
#   image types.

# 20170209 bkw:
# - Take over maintenance
# - i486 => i586
# - Add latest fixes from upstream's git
# - Get rid of redundant stripping of binaries and gzipping
#   of man pages (upstream's 'make install' already does it)
# - Don't install README.INSTALL

# Patch to add potential support for various image formats. This patch
# doesn't actually contain any code for decoding/displaying new image
# formats. All it does is add file extensions and magic to the list
# of filetypes qiv will attempt to display via imlib and/or pixbuf.
# It's up to imlib/pixbuf to actually support the image types. Some of
# these are already supported in Slackware, a few require optional deps
# (see README).

# For the optional ones (e.g. webp), this patch doesn't do any harm
# if the support library's not installed. All it does is make qiv warn
# "Unable to read file" on stderr, instead of silently skipping it.

# Three sed expressions here. In order:
# 1. Make qiv build with our compiler flags.
# 2. Disable the test, since it requires X to be running and
#    accepting connections from root.
# 3. Put man page where Slackware likes them.
