+Build instructions (using linux)
+
+1. Install the Tizen SDK
+
+http://www.tizen.org
+
+To use an alternative Java SDK to run the Tizen IDE (eclipse), edit ~/.profile 
+
+export JAVA_HOME=/opt/jdk1.6.0_45
+export PATH=${PATH}:${JAVA_HOME}/bin
+
+2. Add the following to your ~/.bashrc file
+
+export TIZEN_SDK=${HOME}/tizen-sdk
+export TIZEN_ROOTSTRAP=${TIZEN_SDK}/platforms/tizen2.1/rootstraps/tizen-device-2.1.native
+export TIZEN_BIN=${TIZEN_SDK}/tools/arm-linux-gnueabi-gcc-4.5/bin
+export TIZEN_LIBS=${HOME}/tizen-lib
+export PATH=${PATH}:${TIZEN_BIN}:~/bin
+export CHOST=arm-linux-gnueabi
+export LDFLAGS="--sysroot=${TIZEN_ROOTSTRAP} -L${TIZEN_LIBS}/lib"
+export CPPFLAGS="--sysroot=${TIZEN_ROOTSTRAP} -fmessage-length=0 -fPIC\
+  -I${TIZEN_ROOTSTRAP}/usr/include -I${TIZEN_LIBS}/include"
+export CFLAGS=${CPPFLAGS}
+
+3. Build dependencies
+
+ See: "Building the libraries" under:
+ http://wiki.scummvm.org/index.php/Compiling_ScummVM/MinGW#Building_the_libraries
+ for instructions on how to obtain these modules
+
+ 3.1 zlib
+
+ $ ./configure --static --prefix=${TIZEN_LIBS}
+ $ make && make install
+
+ 3.2 freetype, libtheora, libogg, libvorbis, libmad, FLAC
+
+ $ ./configure --host=arm-linux-gnueabi --prefix=${TIZEN_LIBS} --disable-shared
+ $ make && make install
+
+ Note: you can ignore the ranlib errors when doing make install.
+
+ Modify the resulting ~/tizen-lib/bin/freetype-config file to include -lz when printing libs
+
+ 3.3 Linker ordering: scummvm, freetype, theoradec, vorbis, vorbisfile, mad, FLAC, ogg, z
+
+4. Build the ScummVM base library:
+
+  ./configure --host=tizen --enable-release --with-freetype2-prefix=${TIZEN_LIBS}/bin
+
+  For development:
+
+  ./configure --host=tizen --enable-verbose-build --enable-debug
+
+5. Build the front end application using Tizen IDE
+
+ Copy the scummvm/dists/bada folder into a clean directory
+ outside of the scummvm package. Start the BADA IDE then
+ choose this folder as the eclipse workspace. Click
+ Project / Build.
+
+Links:

+A short turorial on implementing OpenGL ES 1.1 in BADA:

+ http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html
+ http://www.cl.cam.ac.uk/~mgk25/download/ucs-fonts-75dpi100dpi.tar.gz
+
+ Then run the following command:
+ $ ./ucs2any.pl 100dpi/helvB14.bdf MAPPINGS/8859-1.TXT iso8859-1 \
+   MAPPINGS/8859-2.TXT iso8859-2 MAPPINGS/8859-3.TXT iso8859-3
+
+=====================================================================
+Archived build instruction for BADA/cygwin
+
+1. Install BADA SDK (requires free registration):
+
+ http://developer.bada.com/apis/index.do
+
+2. Install Cygwin:
+
+ http://www.cygwin.com/
+
+ Add the following to your cygwin .bash_profile:
+
+ alias mmake=/cygdrive/c/MinGW/bin/mingw32-make.exe
+ export BADA_SDK=/cygdrive/c/bada/1.2.1
+ export ARM_BIN=c:/bada/1.2.1/Tools/Toolchains/ARM/bin
+ export CPPFLAGS="-fpic -fshort-wchar -mcpu=cortex-a8 -mfpu=vfpv3 \
+                  -mfloat-abi=hard -mlittle-endian -mthumb-interwork -Wno-psabi \
+                  -fno-strict-aliasing -fno-short-enums"
+ export LDFLAGS="-nostdlib -lc-newlib -lm-newlib -LC:/bada/1.2.1/Model/Wave_LP1/Target"
+ #export PATH=${BADA_SDK}/Tools/Toolchains/Win32/bin:${PATH}
+ export PATH=${BADA_SDK}/Tools/Toolchains/ARM/bin:~/utils:${PATH}
+ alias gcc=${ARM_BIN}/arm-samsung-nucleuseabi-gcc.exe
+ alias ar=${ARM_BIN}/arm-samsung-nucleuseabi-ar.exe
+
+ The following were added to ~/utils for zlib:
+
+ ar:
+ #!/bin/sh
+ ${ARM_BIN}/arm-samsung-nucleuseabi-ar.exe $*
+
+ gcc:
+ #!/bin/sh
+ ${ARM_BIN}/arm-samsung-nucleuseabi-gcc.exe $*
