# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       poppler-compat
# Descr:     poppler libraries extracted from older releases.
#            Use for compatibility reasons on slackware-current,
#            after an update of poppler.
# 
# -----------------------------------------------------------------------------

# Set initial variables:

PRGNAM=poppler-compat
# Set the VERSION to the most recent poppler package version we use:
VERSION=${VERSION:-24.03.0}
TAG=${TAG:-"alien"}
BUILD=${BUILD:-1}

# Where do we look for sources?
SRCDIR=$(cd $(dirname $0); pwd)

# Place to build (TMP) package (PKG) and output (OUTPUT) the program:
TMP=${TMP:-/tmp/build}
PKG=$TMP/package-$PRGNAM
OUTPUT=${OUTPUT:-/tmp}
