-
-Here is a hopefully informative mini-rant about shared library support
-for mupdf.
-
-Upstream doesn't do shared libraries and doesn't recommend distro
-packages use them. This build used to follow that advice. However,
-mupdf is just too large to use as a static library. We end up with a
-47MB libmupdf.a, plus 7 33MB binaries. *Every* distro I've looked at
-ships mupdf as shared libs, despite upstream's policy.
-
-A long time ago (in 2013), I used to patch mupdf for shared lib support,
-but I removed it when it stopped applying cleanly. Thomas Morper on the
-slackbuilds-users mailing list recently (2018) asked if I could include
-a patch (from LFS) that adds shared library support, so starting with
-mupdf 1.13.0, BUILD 2, we have shared libraries again.
-
-In case someone *really* disagrees with this change, I added a STATIC=yes
-environment setting. If you use this, you get static libs and no
-shared ones, per upstream's policy. This has been tested and works for
-1.13.0-2, but be aware that I probably won't be testing static builds
-for every mupdf release. If you run into trouble, email me and/or the
-slackbuilds-users list.
-
-The library versioning scheme I had to use is unfortunate. The major
-soname version is supposed to only change when there's an incompatible ABI
-change. The way I'm doing it, it changes for every mupdf release [*]. This
-is because upstream doesn't tell us when the ABI changes, because it's
-not relevant for them. They support only static libs specifically to
-avoid the headache of having to track and minimize ABI changes. Whenever
-they want to change the ABI, they just do it. Anything built against the
-old version will keep working fine, because it's statically linked. With
-shared libs, I have to invent my own library versioning scheme.
-
-The end result of this is, I (humble packager) can't easily tell when
-the ABI has changed, so I treat every release [*] as an ABI change. Means
-anything linked with libmupdf will fail with 'cannot open shared object
-file' after a mupdf upgrade, so it'll have to be rebuilt. The alternative
-would be to use unversioned shared libs, which would (seem to) avoid
-the need to rebuild... but whenever the undocumented ABI changed, we'd
-get weird behaviour and segfaults instead of a clean error message.
-
-The shared library patch used here is by me (B. Watson), based on a
-patch from Linux From Scratch. The original LFS patch doesn't include
-versioned libs, I suspect becase in LFS you tend to upgrade the entire
-OS by rebuilding it, instead of upgrading just one library.
-
-Right now, the only SBo builds affected by mupdf upgrades will be
-zathura-pdf-mupdf and possibly fbpdf (if built with optional mupdf
-support). Both have been tested with shared mupdf, and both compile and
-run cleanly.
-
-[*] Actually, not micro-version point releases (e.g. 1.13.0 => 1.13.1).
-    Hopefully this doesn't cause a problem later. Upstream has just
-    switched to a major.minor.micro version scheme starting with 1.13.0,
-    so I don't know how often there will be micro-version bumps, and
-    whether or not they'll have ABI changes.

 # 20170621 bkw: fix build with -current's newer openjpeg, BUILD=2.
 # 20170122 bkw: update for 1.10a.
 
+# Notes for 1.18.0:
+# - This script can no longer build older versions, too many changes.
+# - Upstream *finally* supports building as a shared library, so I and
+#   all other distro packagers can stop patching it... except the
+#   shared lib is unversioned, which means upgrades would cause more
+#   breakage than they should. So there's still some trickery here to
+#   build a versioned solib.
+# - I've got rid of the STATIC=yes option and now only build shared libs.
+#   As a side effect, libmupdf-third is gone, but I've included a
+#   placeholder so stuff that links with it, will work without patching.
+# - gumbo (HTML parser) is now a hard dep. The source is bundled, so
+#   there's no need to create a new gumbo SlackBuild, but it does mean
+#   the mupdf shared lib has grown in size.
+# - mupdf-gl uses freeglut. The version we have in 14.2 is new enough to
+#   build with, but old enough that you can't copy text from mupdf-gl.
+#   So we build the bundled version here.
+# - API docs are now included in the package.
+# - Now using upstream's icons, including scalable SVG.
+# - Add missing doinst.sh
+# - There's now the option to build with tesseract and leptonica,
+#   but it's disabled in this script. I have yet to get it to
+#   actually *do* anything other than fail to build (when using
+#   upstream's tesseract/leptonica forks) or complain about being
+#   unable to load eng.traineddata (using SBo tesseract/leptonica,
+#   and yes eng.traineddata is fine). Until I work out what's wrong,
+#   or upstream releases a new version, this script doesn't support
+#   building with tesseract. Don't contact me about this before March
+#   1, 2021, unless you actually have a patch that fixes it. After
+#   that, if this message is still here, feel free to remind me to
+#   revisit it.
+# - Slackware 14.2's libcrypto (from openssl) is too old for mupdf,
+#   and there's no bundled souce for it. So currently mupdf is being
+#   built without libcrypto. Hope that's OK.
