# Record toolchain & other info for the build log:

# Paths to skeleton port's source & real Slackware source tree:
slackset_var_cwds

# Detect whether we're building for /patches:
# This function sets the variable 'SLACKPATCHING'

# 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 $PKGNAM-$VERSION || failextract

# Also search paths under /usr/local:
cat $CWD/lua.usr.local.patch | patch -p1 --verbose || exit 1

# Fix luaconf.h header to use lib$LIBDIRSUFFIX:
sed -i "s|lib/lua|lib$LIBDIRSUFFIX/lua|" src/luaconf.h

# Build:
make linux \
  MYCFLAGS="$SLKCFLAGS" \
  INSTALL_TOP=/usr \
  INSTALL_LIB=/usr/lib${LIBDIRSUFFIX} \
  INSTALL_LMOD=/usr/share/lua/$(echo $VERSION | cut -f 1-2 -d .) \
  INSTALL_CMOD=/usr/lib${LIBDIRSUFFIX}/lua/$(echo $VERSION | cut -f 1-2 -d .) || failmake

# Install into package:
make linux install \
  MYCFLAGS="$SLKCFLAGS" \
  INSTALL_TOP=$PKG/usr \
  INSTALL_LIB=$PKG/usr/lib${LIBDIRSUFFIX} \
  INSTALL_LMOD=$PKG/usr/share/lua/$(echo $VERSION | cut -f 1-2 -d .) \
  INSTALL_CMOD=$PKG/usr/lib${LIBDIRSUFFIX}/lua/$(echo $VERSION | cut -f 1-2 -d .) || failinstall

# Now let's build the shared library
mkdir -p shared
cd shared
  ar -x $PKG/usr/lib${LIBDIRSUFFIX}/liblua.a || failinstall
  gcc -ldl -lreadline -lhistory -lncurses -lm -shared *.o -o liblua.so.$VERSION || failmake
  cp -a liblua.so.$VERSION $PKG/usr/lib${LIBDIRSUFFIX} || failinstall
  ( cd $PKG/usr/lib${LIBDIRSUFFIX}
    ln -vfs liblua.so.$VERSION liblua.so.$(echo $VERSION | cut -f 1-2 -d .)
    ln -vfs liblua.so.$VERSION liblua.so.$(echo $VERSION | cut -f 1 -d .)
    ln -vfs liblua.so.$VERSION liblua.so
  )
cd ..

## On second thought, this *might* be useful
## Don't ship the static library:
#rm -f $PKG/usr/lib${LIBDIRSUFFIX}/liblua.a

# and install the pkgconfig file
mkdir -p $PKG/usr/lib${LIBDIRSUFFIX}/pkgconfig
cat $CWD/lua.pc | sed "s/%V%/$(echo $VERSION | cut -f 1-2 -d .)/g" | sed "s/%R%/$VERSION/g" | sed "s/%LIBDIRSUFFIX%/$LIBDIRSUFFIX/g" > $PKG/usr/lib${LIBDIRSUFFIX}/pkgconfig/lua.pc
