# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/ap/amp

# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM
mkpkgdirs # Delete & re-create temporary directories then cd into $TMPBUILD

# Extract source:
tar xvvf $CWD/$PKGNAM-$VERSION.tar.!(*sign|*asc|*sig)
cd $PKGNAM-*/ || exit 1

# Create package framework:
mkdir -p $PKG/usr/{bin,man/man1,doc/$PKGNAM-$VERSION}

# Apply patch for gcc 3.4:
zcat $CWD/amp-gcc34.diff.gz | patch -p1 --verbose --backup --suffix=.orig || exit 1
# Avoid crashes caused by using agressive optimization with newer compilers:
zcat $CWD/amp.do.not.overoptimize.diff.gz | patch -p1 --verbose --backup --suffix=.orig || exit 1

# Configure:
./configure \
   --prefix=/usr \
   --build=${SLK_ARCH_BUILD} || failconfig

# No armv4l in ARMedslack (armv4l will be detected when built on a RiscPC):

# Build:
make $NUMJOBS || make || failmake

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
slack_delete_lafiles # delete usr/lib{,64}/*.la
#slackstriprpaths     # strip rpaths
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
slackhlinks     # search for any hard links
