X Plane 11 Global Scenery Dlccodex Best Better

Draft

This page was roughly updated from the SDL2 version, but needs to be inspected for details that are out of date, and a few SDL2isms need to be cleaned out still, too. Read this page with some skepticism for now.

Existing documentation

A lot of information can be found in README-android.

This page is more walkthrough-oriented.

Pre-requisites

Install minimal Java environment. For instance, in Debian/Ubuntu:

sudo apt install openjdk-17-jdk ant android-sdk-platform-tools-common

Install NDK (tested with [https://dl.google.com/android/repository/android-ndk-r10e-linux-x86_64.zip r10e])
Install the latest SDK, run tools/bin/sdkmanager (or tools/android pre-2017) and install one API (>= 31)
Configure your environment variables, e.g.:

PATH="/usr/src/android-ndk-rXXx:$PATH"                  # for 'ndk-build'
PATH="/usr/src/android-sdk-linux/tools:$PATH"           # for 'android'
PATH="/usr/src/android-sdk-linux/platform-tools:$PATH"  # for 'adb'
export ANDROID_HOME="/usr/src/android-sdk-linux"        # for gradle
export ANDROID_NDK_HOME="/usr/src/android-ndk-rXXx"     # for gradle

Simple builds

SDL wrapper for simple programs

Compile a sample app (calls ndk-build):

cd /usr/src/SDL3/build-scripts/
./androidbuild.sh org.libsdl.testgles ../test/testgles.c

Follow the instructions to install on your device:

cd /usr/src/SDL3/build/org.libsdl.testgles/
./gradlew installDebug

Notes:

multiple targets armeabi-v7a/arm64-v8a/x86/x86_64 compilation
application doesn't quit

Troubleshooting

use OpenJDK 17: execute sudo update-alternatives --config java and select jdk-17 as default; or use JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64 ./gradlew
javax/xml/bind/annotation/XmlSchema, Could not initialize class com.android.sdklib.repository.AndroidSdkHandler: check the Android Gradle Plugin version in /android-project/build.gradle, e.g. classpath 'com.android.tools.build:gradle:3.1.0'
You can customize the Gradle version in /android-project/gradle/wrapper/gradle-wrapper.properties: distributionUrl=https\://services.gradle.org/distributions/gradle-4.9-all.zip
You can customize your SDK/NDK versions in android-project/app/build.gradle:

android {
    buildToolsVersion "28.0.1"
    compileSdkVersion 28

You can customize your targets depending on the NDK version:

externalNativeBuild {
    ndkBuild {
        arguments "APP_PLATFORM=android-14"
        abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'

ABIs [x86_64, arm64-v8a] are not supported for platform. Supported ABIs are [armeabi, armeabi-v7a, x86, mips]: upgrade to NDK >= 10
TODO: check how we can use the distro's gradle instead of executing stuff from the Internet - apt install gradle libgradle-android-plugin-java

SDL wrapper + SDL_image NDK module

Let's modify SDL3_image/showimage.c to show a simple embedded image (e.g. XPM).

#include <SDL3/SDL.h>
#include <SDL3/SDL_main.h>
#include <SDL3/SDL_image.h>

/* XPM */
static char * icon_xpm[] = {
  "32 23 3 1",
  "     c #FFFFFF",
  ".    c #000000",
  "+    c #FFFF00",
  "                                ",
  "            ........            ",
  "          ..++++++++..          ",
  "         .++++++++++++.         ",
  "        .++++++++++++++.        ",
  "       .++++++++++++++++.       ",
  "      .++++++++++++++++++.      ",
  "      .+++....++++....+++.      ",
  "     .++++.. .++++.. .++++.     ",
  "     .++++....++++....++++.     ",
  "     .++++++++++++++++++++.     ",
  "     .++++++++++++++++++++.     ",
  "     .+++++++++..+++++++++.     ",
  "     .+++++++++..+++++++++.     ",
  "     .++++++++++++++++++++.     ",
  "      .++++++++++++++++++.      ",
  "      .++...++++++++...++.      ",
  "       .++............++.       ",
  "        .++..........++.        ",
  "         .+++......+++.         ",
  "          ..++++++++..          ",
  "            ........            ",
  "                                "};

int main(int argc, char *argv[])
{
  SDL_Window *window;
  SDL_Renderer *renderer;
  SDL_Surface *surface;
  SDL_Texture *texture;
  int done;
  SDL_Event event;

  if (SDL_CreateWindowAndRenderer("Show a simple image", 0, 0, 0, &window, &renderer) < 0) {
    SDL_LogError(SDL_LOG_CATEGORY_APPLICATION,
        "SDL_CreateWindowAndRenderer() failed: %s", SDL_GetError());
    return(2);
  }

  surface = IMG_ReadXPMFromArray(icon_xpm);
  texture = SDL_CreateTextureFromSurface(renderer, surface);
  if (!texture) {
    SDL_LogError(SDL_LOG_CATEGORY_APPLICATION,
        "Couldn't load texture: %s", SDL_GetError());
    return(2);
  }
  SDL_SetWindowSize(window, 800, 480);

  done = 0;
  while (!done) {
    while (SDL_PollEvent(&event)) {
      if (event.type == SDL_EVENT_QUIT)
        done = 1;
    }
    SDL_RenderTexture(renderer, texture, NULL, NULL);
    SDL_RenderPresent(renderer);
    SDL_Delay(100);
  }
  SDL_DestroyTexture(texture);

  SDL_Quit();
  return(0);
}

Then let's make an Android app out of it. To compile:

cd /usr/src/SDL3/build-scripts/
./androidbuild.sh org.libsdl.showimage /usr/src/SDL3_image/showimage.c
cd /usr/src/SDL3/build/org.libsdl.showimage/
ln -s /usr/src/SDL3_image jni/
ln -s /usr/src/SDL3_image/external/libwebp-0.3.0 jni/webp
sed -i -e 's/^LOCAL_SHARED_LIBRARIES.*/& SDL3_image/' jni/src/Android.mk
ndk-build -j$(nproc)
ant debug install

Notes:

application doesn't restart properly

Build an autotools-friendly environment

You use autotools in your project and can't be bothering understanding ndk-build's cryptic errors? This guide is for you!

Note: this environment can be used for CMake too.

Compile a shared binaries bundle for SDL and SDL_*

Get the latests SDL3_* releases:

(FIXME: this needs to be updated for SDL3.)

cd /usr/src/
wget https://libsdl.org/release/SDL2-2.0.5.tar.gz
wget https://www.libsdl.org/projects/SDL_image/release/SDL2_image-2.0.1.tar.gz
wget https://www.libsdl.org/projects/SDL_mixer/release/SDL2_mixer-2.0.1.tar.gz
wget https://www.libsdl.org/projects/SDL_net/release/SDL2_net-2.0.1.tar.gz
wget https://www.libsdl.org/projects/SDL_ttf/release/SDL2_ttf-2.0.14.tar.gz

tar xf SDL2-2.0.5.tar.gz
tar xf SDL2_image-2.0.1.tar.gz
tar xf SDL2_mixer-2.0.1.tar.gz
tar xf SDL2_net-2.0.1.tar.gz
tar xf SDL2_ttf-2.0.14.tar.gz

ln -s SDL2-2.0.5 SDL2
ln -s SDL2_image-2.0.1 SDL2_image
ln -s SDL2_mixer-2.0.1 SDL2_mixer
ln -s SDL2_net-2.0.1 SDL2_net
ln -s SDL2_ttf-2.0.14 SDL2_ttf

Start with a minimal build:

cd /usr/src/SDL3/
#git checkout -- .  # remove traces of previous builds
cd build-scripts/
# edit androidbuild.sh and modify $ANDROID update project --target android-XX
./androidbuild.sh org.libsdl /dev/null
# doesn't matter if the actual build fails, it's just for setup
cd ../build/org.libsdl/

Remove reference to our dummy file:

rm -rf jni/src/

Reference SDL_image, SDL_mixer, SDL_ttf, and their dependencies, as NDK modules:

ln -s /usr/src/SDL3_image jni/
ln -s /usr/src/SDL3_image/external/libwebp-0.3.0 jni/webp
ln -s /usr/src/SDL3_mixer jni/
ln -s /usr/src/SDL3_mixer/external/libmikmod-3.1.12 jni/libmikmod
ln -s /usr/src/SDL3_mixer/external/smpeg2-2.0.0 jni/smpeg2
ln -s /usr/src/SDL3_net jni/
ln -s /usr/src/SDL3_ttf jni/

Optionnaly edit jni/Android.mk to disable some formats, e.g.:

SUPPORT_MP3_SMPEG := false
include $(call all-subdir-makefiles)

Launch the build!

ndk-build -j$(nproc)

Note: no need to add System.loadLibrary calls in SDLActivity.java, your application will be linked to them and Android's ld-linux loads them automatically.

Install SDL in a GCC toolchain

Now:

Copy the NDK into a traditional GCC toolchain (leave android-14 as-is):

/usr/src/android-ndk-r8c/build/tools/make-standalone-toolchain.sh \
  --platform=android-14 --install-dir=/usr/src/ndk-standalone-14-arm --arch=arm

Set your PATH (important, do it before any build):

NDK_STANDALONE=/usr/src/ndk-standalone-14-arm
PATH=$NDK_STANDALONE/bin:$PATH

Install the SDL3 binaries in the toolchain:

cd /usr/src/SDL3/build/org.libsdl/
for i in libs/armeabi/*; do ln -nfs $(pwd)/$i $NDK_STANDALONE/sysroot/usr/lib/; done
mkdir $NDK_STANDALONE/sysroot/usr/include/SDL3/
cp jni/SDL/include/* $NDK_STANDALONE/sysroot/usr/include/SDL3/
cp jni/*/SDL*.h $NDK_STANDALONE/sysroot/usr/include/SDL3/

Install pkg-config and install a host-triplet-prefixed symlink in the PATH (auto-detected by autoconf):

VERSION=0.9.12
cd /usr/src/
wget http://rabbit.dereferenced.org/~nenolod/distfiles/pkgconf-$VERSION.tar.gz
tar xf pkgconf-$VERSION.tar.gz
cd pkgconf-$VERSION/
mkdir native-android/ && cd native-android/
../configure --prefix=$NDK_STANDALONE/sysroot/usr
make -j$(nproc)
make install
ln -s ../sysroot/usr/bin/pkgconf $NDK_STANDALONE/bin/arm-linux-androideabi-pkg-config
mkdir $NDK_STANDALONE/sysroot/usr/lib/pkgconfig/

Install pkg-config .pc files for SDL:

X Plane 11 Global Scenery Dlccodex Best Better

Alex stared at his monitor, frustration bubbling. His X-Plane 11 simulation was… empty. Or rather, it was limited. A beautiful, high-fidelity Cessna 172 sat on the runway, but it was sitting in a generic, blurry wasteland.

The "best" scenery in X-Plane 11 isn't just one file; it is a combination of accurate elevation mesh, detailed land textures (orthophotos), and accurate building placement (OpenStreetMap data).

Open your main X-Plane 11 installation folder.

Detailed elevation maps that accurately replicate mountain ranges, valleys, and coastlines. x plane 11 global scenery dlccodex best

Obtain the X-Plane 11 Global Scenery DLC (CODEX) files.

The "best" X-Plane 11 experience comes from a mix of the official Global Scenery DLC and community-driven enhancements. By organizing your scenery_packs.ini correctly and layering satellite imagery over the default mesh, you transform a simulator into a mirror of the real world.

For users exploring the , unlocking the full, high-resolution world is essential. In this guide, we break down what this DLC includes, why the CODEX release is popular, and the best ways to enhance your global scenery for the ultimate experience.

If you ask veteran simmers what the absolute scenery upgrade is, they won't point you to a specific airport DLC—they will point you to Ortho4XP .

The default X-Plane trees can look sparse. This DLC replaces the global vegetation map with accurate tree types and densities, significantly improving the "vibe" of VFR (Visual Flight Rules) flying. Optimizing the "Scenery_packs.ini" (The Codex of X-Plane)

Landing at a major international hub or a remote dirt strip feels authentic. The 3D scenery elements adapt to local architectural styles, making global touring a visually diverse experience. Performance and Storage Optimization

Building other dependencies

You can add any other libraries (e.g.: SDL2_gfx, freetype, gettext, gmp...) using commands like:

mkdir cross-android/ && cd cross-android/
../configure --host=arm-linux-androideabi --prefix=$NDK_STANDALONE/sysroot/usr \
  --with-some-option --enable-another-option \
  --disable-shared
make -j$(nproc)
make install

Static builds (--disable-shared) are recommended for simplicity (no additional .so to declare).

(FIXME: is there an SDL3_gfx?)

Example with SDL2_gfx:
VERSION=1.0.3
wget http://www.ferzkopp.net/Software/SDL2_gfx/SDL2_gfx-$VERSION.tar.gz
tar xf SDL2_gfx-$VERSION.tar.gz
mv SDL2_gfx-$VERSION/ SDL2_gfx/
cd SDL2_gfx/
mkdir cross-android/ && cd cross-android/
../configure --host=arm-linux-androideabi --prefix=$NDK_STANDALONE/sysroot/usr \
  --disable-shared --disable-mmx
make -j$(nproc)
make install

You can compile YOUR application using this technique, with some more steps to tell Android how to run it using JNI.

Build your autotools app

First, prepare an Android project:

Copy and adapt the /usr/src/SDL3/android-project skeleton as explained in README-android.md. You can leave it as-is in a first step.
Make links to the SDL binaries as well:

mkdir -p libs/armeabi/
for i in /usr/src/SDL3/build/org.libsdl/libs/armeabi/*; do ln -nfs $i libs/armeabi/; done

Make your project Android-aware:

Add /usr/src/SDL3/src/main/android/SDL_android_main.c in your project (comment out the line referencing "SDL_internal.h"). Compile it as C (not C++).
In your configure.ac, detect Android:

AM_CONDITIONAL(ANDROID, test "$host" = "arm-unknown-linux-androideabi")

In your Makefile.am, tell Automake you'll build executables as libraries, using something like:

if ANDROID
<!--  Build .so JNI libs rather than executables -->
  AM_CFLAGS = -fPIC
  AM_LDFLAGS += -shared
  COMMON_OBJS += SDL_android_main.c
endif

Cross-compile your project using the GCC toolchain environment we created:

PATH=$NDK_STANDALONE/bin:$PATH
mkdir cross-android/ && cd cross-android/
../configure --host=arm-linux-androideabi \
  --prefix=/android-aint-posix \
  --with-your-option --enable-your-other-option ...
make

Do this again for any additional arch you want to support (TODO: see how to support armeabi-v7a and document what devices support it); something like:

mkdir cross-android-v7a/ && cd cross-android-v7a/
# .o: -march=armv5te -mtune=xscale -msoft-float -mthumb  =>  -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp -mthumb
# .so: -march=armv7-a -Wl,--fix-cortex-a8
CFLAGS="-g -O2 -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp -mthumb" LFDLAGS="-march=armv7-a -Wl,--fix-cortex-a8" \
  ../configure --host=arm-linux-androideabi \
  ...

Now you can install your pre-built binaries and build the Android project:

Copy your program in android-project/libs/armeabi/libmain.so.
Build your Android .apk:

android update project --name your_app --path . --target android-XX
ant debug
ant installd

You can run the application remotely:

adb shell am start -a android.intenon.MAIN -n org.libsdl.app/org.libsdl.app.SDLActivity  # replace with your app package

Your SDL3 Android app is running!

Build your CMake app

(Work In Progress)

You can use our Android GCC toolchain using a simple toolchain file:

# CMake toolchain file
SET(CMAKE_SYSTEM_NAME Linux)  # Tell CMake we're cross-compiling
include(CMakeForceCompiler)
# Prefix detection only works with compiler id "GNU"
CMAKE_FORCE_C_COMPILER(arm-linux-androideabi-gcc GNU)
SET(ANDROID TRUE)

You then call CMake like this:

PATH=$NDK_STANDALONE/bin:$PATH
cmake \
  -D CMAKE_TOOLCHAIN_FILE=../android_toolchain.cmake \
  ...

Troubleshootings

If ant installd categorically refuses to install with Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE], even if you have free local storage, that may mean anything. Check logcat first:

adb logcat

If the error logs are not helpful (likely ;')) try locating all past traces of the application:

find / -name "org...."

and remove them all.

If the problem persists, you may try installing on the SD card:

adb install -s bin/app-debug.apk

If you get in your logcat:

SDL: Couldn't locate Java callbacks, check that they're named and typed correctly

this probably means your SDLActivity.java is out-of-sync with your libSDL3.so.
