# Slackware build script for GraphicsMagick

# Originally written by Giovanne Castro <email removed>.

# Updated by B. Watson <yalhcru@gmail.com>, as the original author is
# MIA. Original version had no license; I'm licensing the update under the
# terms of the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20210910 bkw: update for v1.3.36.
# 20201019 bkw: update for v1.3.35.
# 20200111 bkw: update for v1.3.34, quit using sourceforge dl link.
# 20191130 bkw: update for v1.3.33.
# 20181201 bkw: update for v1.3.31 (BUILD=1 again).

# 20181126 bkw:
# - fix the perl module. at one point it really did work, but lately
#   people (including me) were getting 'undefined symbol' errors when
#   trying to load the perl module (e.g. by running findimagedupes).
#   Thanks to Kevin Smallman for a very helpful bug report.
# - update find/chmod stuff to my personal template.
# - BUILD=2

# 20180627 bkw:
# - updated for v1.3.30.
# - get rid of the need to build/install/build again for the Tcl bindings.
# - actually install the damn perl module (when did *that* break?)
# - get rid of static tcl/tk libs
# - get rid of --disable-openmp (but add OPENMP=no just in case)

# 20180123 bkw: updated for v1.3.28
# 20171219 bkw: updated for v1.3.27, added last few missing delegates
# 20170708 bkw: updated for v1.3.26
# 20161016 bkw: updated for v1.3.25
# 20151127 bkw: fix build on -current, in anticipation of 14.2

# 20150803 bkw:
# - updated for v1.3.21
# - install docs to /usr/doc/$PRGNAM-$VERSION, not /usr/share/doc
# - build perl bindings (PerlMagick)
# - build Tcl bindings (TclMagick)
# - document optional deps in README

### Build the perl module, if not disabled.

# In the olden days, PerlMagick was a separate module, not part of
# GraphicsMagick, and it had its own SlackBuild. These days, PerlMagick
# is integrated into the GraphicsMagick source. Supposedly, PerlMagick
# has to be built after GraphicsMagick is installed system-wide, but
# I've come up with functional (if unattractive) way around that.
# 20181126 bkw: ...which stopped working with 1.3.30. Updated this
# so it works again, and as a side effect, it's slightly less repulsive
# to look at.
