+# Note:

+# This file is used to build HarfBuzz within the Android
+# platform itself. If you need to compile HarfBuzz to
+# ship with your Android NDK app, you can use the autotools
+# build system to do so. To do that you need to install a
+# "standalone" toolchain with the NDK, eg:
+#
+# ndk/build/tools/make-standalone-toolchain.sh \
+# --platform=android-18 \
+# --install-dir=/prefix
+#
+# Set PLATFORM_PREFIX eng var to that prefix and make sure
+# the cross-compile tools from PLATFORM_PREFIX are in path.
+# Configure and install HarfBuzz:
+#
+# ./configure --host=arm-linux-androideabi \
+# --prefix=$PLATFORM_PREFIX \
+# --enable-static \
+# --with-freetype \
+# PKG_CONFIG_LIBDIR=$PLATFORM_PREFIX/lib/pkgconfig
+# make install
+#
+# You can first build FreeType the same way:
+#
+# ./configure --host=arm-linux-androideabi \
+# --prefix=$PLATFORM_PREFIX \
+# --enable-static \
+# --without-png \
+# PKG_CONFIG_LIBDIR=$PLATFORM_PREFIX/lib/pkgconfig
+# make install

# build the harfbuzz static library

-# Uses UCDN instead of ICU for Unicode data, and comes with
-# FreeType glue layer. Most useful for NDK apps that want
-# to bundle FreeType and HarfBuzz, though it's trivial to
-# build for Android using the autoconf toolchain; eg:
+# If you need to compile HarfBuzz for your NDK app, you
+# might want to include UCDN instead of ICU for Unicode
+# data, and you probably need hb-ft also.
