# Package metadata:
export PKGNAM=emacs
export VERSION=${VERSION:-29.4}
export BUILD=${BUILD:-2}
slack_var_pkgseries

# If building in /patches for a Stable Release, we drop the packages into the
# '/patches' directory within the configured Slackware tree:
slack_findpkgstore_is_stablerelease && {
    export PKGSTORE=$PORTPATCHPKGS
    export PKGSERIES=/ # unset as it's not required for patches
    export BUILD=2_slack25.0
    mkdir -vpm755 $PKGSTORE/$PKGSERIES ;}

# Set package name:
export SLACKPACKAGE=$PKGNAM-$VERSION-$PKGARCH-$BUILD.txz

# Ensure base ARM packages are installed first:
slackbasedeps

# Ensure $PKGNAM isn't already installed:
slackfailpkgdeps $PKGNAM || removepkg $PKGNAM

# And for removing the old emacs packages:
( cd /var/log/packages ; removepkg emacs* )

# Ensure specific build dependencies (mainly libraries):
