Create a module compatible with the NDK build-system
====================================================

- Use your own cross-compiler for Android, or export the one from the
  NDK:

  /usr/src/android-ndk-r7c/build/tools/make-standalone-toolchain.sh \
    --platform=android-9 \
    --install-dir=/usr/src/ndk-standalone-9

- Build FreeGLUT with a '/freeglut' prefix :

  PATH=/usr/src/ndk-standalone-9/bin:$PATH
  cd /usr/src/freeglut-3.0.0/
  mkdir cross-android-module-gles2/
  cd cross-android-module-gles2/
  cmake \
    -D CMAKE_TOOLCHAIN_FILE=../android_toolchain.cmake \
    -D CMAKE_INSTALL_PREFIX=/freeglut-gles2 \
    -D CMAKE_BUILD_TYPE=Debug \
    -D FREEGLUT_GLES2=ON \
    -D FREEGLUT_BUILD_DEMOS=NO \
    ..
  make -j4
  make install DESTDIR=$(pwd)

- Copy Android.mk in the new 'freeglut/' directory :

  cp ../android/gles2/Android.mk freeglut-gles2/

- Reference this module in your jni/Android.mk:

  LOCAL_STATIC_LIBRARIES := ... freeglut-gles2
  ...
  $(call import-module,freeglut-gles2)

- You now can point your NDK_MODULE_PATH to this module!

  ndk-build NDK_MODULE_PATH=/usr/src/freeglut-3.0.0/cross-android-module/freeglut-gles2/


Compile FreeGLUT for a traditional cross-compiler environment
=============================================================

- Use your own cross-compiler for Android, or export the one from the
  NDK:

  /usr/src/android-ndk-r7c/build/tools/make-standalone-toolchain.sh \
    --platform=android-9 \
    --install-dir=/usr/src/ndk-standalone-9

- Compile FreeGLUT and install it in your Android cross-compiler path:

  PATH=/usr/src/ndk-standalone-9/bin:$PATH
  cd /usr/src/freeglut-3.0.0/
  mkdir cross-android-toolchain-gles2/
  cd cross-android-toolchain-gles2/
  cmake \
    -D CMAKE_TOOLCHAIN_FILE=../android_toolchain.cmake \
    -D CMAKE_INSTALL_PREFIX=/usr/src/ndk-standalone-9/sysroot/usr \
    -D CMAKE_BUILD_TYPE=Debug \
    -D FREEGLUT_GLES2=ON \
    -D FREEGLUT_BUILD_DEMOS=NO \
    ..
  make -j4
  make install
  # Only static for now:
  rm -f /usr/src/ndk-standalone-9/sysroot/usr/lib/libfreeglut-gles1.so*

- Compile your own project.

For instance if you use the autotools:

  PATH=/usr/src/ndk-standalone-9/bin:$PATH
  export PKG_CONFIG_PATH=/usr/src/ndk-standalone-9/sysroot/usr/share/pkgconfig
  ./configure --host=arm-linux-androideabi --prefix=/somewhere
  make
  make install

If you use CMake, you may want to copy our Android toolchain
'android_toolchain.cmake':

  PATH=/usr/src/ndk-standalone-9/bin:$PATH
  export PKG_CONFIG_PATH=/usr/src/ndk-standalone-9/sysroot/usr/share/pkgconfig
  cp .../android_toolchain.cmake .
  mkdir cross-android/
  cd cross-android/
  cmake \
    -D CMAKE_TOOLCHAIN_FILE=../android_toolchain.cmake \
    -D CMAKE_INSTALL_PREFIX=/somewhere \
    -D CMAKE_BUILD_TYPE=Debug \
    -D MY_PROG_OPTION=something ... \
    ..
  make -j4
  make install
