# Slackware build script for GraphicsMagick

# 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

# 20151127 bkw:
# - fix build on -current, in anticipation of 14.2

### Build the perl module

# 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.

cd PerlMagick

# munge Makefile.PL to build using the includes/libs we just installed
# to $PKG, instead of systemwide ones.

make

# 'make test' will attempt to display an image, if it thinks it's running
# in X. Let's not do this. Also, use the shared libs in $PKG.
# The rungm.sh script sets up the environment so GraphicsMagick will look
# for its support files in the source tree instead of /usr.

### Done with perl module

### Build the tcl module, if & only if GraphicsMagick was already
#   installed system-wide. This means, to get tcl bindings, you have to
#   build twice. You can thank libtool and its .la files (with hard-coded
#   paths) for this stupidity. I could probably spend more time with
#   this and fix it (like the perl stuff above), but I suspect nobody
#   really cares about TclMagick.
