针对arm64架构编译SDL2_arm sdl2-优快云博客

本文介绍如何使用SDL2-2.0.3版本及android-ndk-r20编译适用于Android平台的libSDL2库。通过创建并配置特定的编译脚本androidbuildlibs.sh，针对不同架构如armeabi-v7a、arm64-v8a等生成所需的动态链接库。

源码

SDL使用版本是SDL2-2.0.3（找了许久才找到的SDL2-2.0.3-Android文档类资源-优快云下载）

NDK版本是android-ndk-r20

编译脚本

在SDL2-2.0.3/build-scripts下新建androidbuildlibs.sh，也可拷贝SDL2-2.0.14/build-scripts下的androidbuildlibs.sh，因为我们只想编译libSDL2，所以需要将APP_MODULES修改为“APP_MODULES="SDL2"”

# Android.mk is in srcdir
srcdir=`dirname $0`/..
srcdir=`cd $srcdir && pwd`
cd $srcdir
echo $srcdir  "---------------------"

  if [ "${arg:0:8}" == "NDK_OUT=" ]; then
    obj=${arg#NDK_OUT=}
  elif [ "${arg:0:13}" == "NDK_LIBS_OUT=" ]; then
    lib=${arg#NDK_LIBS_OUT=}
  else
    ndk_args="$ndk_args $arg"
