# Record toolchain & other info for the build log:
slackbuildinfo

# Incase this lags behind the real package version:
SOLIB=1.0.6

# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/$PKGSERIES/$PKGNAM
export PORTCWD=$PWD

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

# Determine the CFLAGS for the known architectures:
case $ARCH in
   arm)     export SLKCFLAGS="-O2 -march=armv4t"
            export LIBDIRSUFFIX="" ;;
   *)       export SLKCFLAGS="-O2" ;;

# This should be ok, since libbz2.so.1.0 will still exist.

# This hack will go away when the ARMv3l toolchain is ready:
# but.. I sort of like it for historical reasons :-)
# I'd never do it like this again..

slackmp         # run makepkg -l y -c n

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