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

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

# Determine the CFLAGS for the known architectures:
case $PORTARCH in

   powerpc) export ARCH_CFLAGS="-O2" ;;

# Extract source:
tar zxvvf $CWD/tcl$VERSION-src.tar.gz
cd tcl$VERSION

# Install docs:
mkdir -p $PKG/usr/doc/tcl$VERSION
cp -a README license.terms \
      $PKG/usr/doc/tcl$VERSION

# Build static version first:
cd unix
CFLAGS="$ARCH_CFLAGS" \
./configure \
   --prefix=/usr \
   --disable-shared || failconfig
make || failmake

# Fix the mkLinks script so that it doesn't make hardlinks.
# In Slackware, we tend to favour symlinks wherever possible:
sed -i -e "s?ln ?ln -s ?g" mkLinks

# Install into package:
make install INSTALL_ROOT=$PKG

# Build shared version:
make clean
CFLAGS="$ARCH_CFLAGS" \
./configure \
   --prefix=/usr \
   --enable-shared || failconfig
make || failmake

# Fix unexpanded ${TCL_DBGX} variables strewn throughout tclConfig.sh:
sed -i -e 's/\@LDFLAGS_DEBUG\@//g' \
       -e 's/\@LDFLAGS_OPTIMIZE\@//g' \
       -e 's/\${TCL_DBGX}//g' tclConfig.sh

# Install the shared version into the package:
make install INSTALL_ROOT=$PKG

# Perform any final checks on the package:
