# Add the scripts that change your environment for 32bit compilation
# (but do not make it executable by default):
mkdir -p $PKG/etc/profile.d
install -o root -m644 $CWD/32dev.sh $PKG/etc/profile.d/32dev.sh
install -o root -m644 $CWD/32dev.csh $PKG/etc/profile.d/32dev.csh

# Add the 'gcc' wrapper script to be used for building 32bit software:
mkdir -p $PKG/usr/bin/32
install -o root -m755 $CWD/gccwrapper $PKG/usr/bin/32/gcc

# Add the 'gfortran' wrapper script to be used for building 32bit software:
mkdir -p $PKG/usr/bin/32
install -o root -m755 $CWD/gfortranwrapper $PKG/usr/bin/32/gfortran

# Add symlinks for cc and g++ stubs:
( cd $PKG/usr/bin/32;
  ln -s gcc g++;
  ln -s gcc cc;
)

# Add symlinks for fortran stubs:
( cd $PKG/usr/bin/32;
  ln -s gfortran f77;
  ln -s gfortran f95;
  ln -s gfortran g77;
  ln -s gfortran g95;

# Add the two scripts that will facilitate converting 32bit Slackware
# packages to a format that is suitable to be installed on 64bit Slackware.
# Since these scripts should be run as root, dump them into a sbin directory:
mkdir -p $PKG/usr/sbin
install -m755 -o root $CWD/convertpkg-compat32 $PKG/usr/sbin/convertpkg-compat32
install -m755 -o root $CWD/massconvert32.sh $PKG/usr/sbin/massconvert32.sh

# Add documentation:
mkdir -p $PKG/usr/doc/$PRGNAM-$VERSION
# Much of this README is from the Slamd64 file:
# http://slackware.org.uk/slamd64/slamd64-current/slamd64-FAQ/Compiling.txt
cat $CWD/README > $PKG/usr/doc/$PRGNAM-$VERSION/README
# Add this script:
cat $0 > $PKG/usr/doc/$PRGNAM-$VERSION/$PRGNAM.SlackBuild

# Add a package description:
mkdir -p $PKG/install
cat $CWD/slack-desc > $PKG/install/slack-desc

# Build the package:
cd $PKG
/sbin/makepkg -l y -c n $TMP/${PRGNAM}-${VERSION}-${ARCH}-${BUILD}${TAG}.tgz
