How to compile Lua 5.3.0 for Android as a dynamic library
This is a tutorial on how to compile Lua 5.3.0 for Android as a dynamic library (liblua.so) using the Windows Eclipse ADT.
1. download and extract Eclipse ADT with the Android SDK for Windows (with a single download, the Eclipse ADT bundle includes everything you need) to C:\Android\adt-bundle-windows-x86-20140702\, then download and extract the current Android NDK for Windows to C:\Android\android-ndk-r10d\ – if not yet done (use your paths accordingly if installed in other directories).
2. run Eclipse ADT (C:\Android\adt-bundle-windows-x86-20140702\eclipse\eclipse.exe) and create a new project with File->New->Android Application Project, fill in some Application, project and package names, use the blank activity template (leave default workspace setting as C:\users\%yourusername%\workspace)
3. Left click on your project then select New -> Folder and choose jni as the folder name
4. Left click on this new folder and select New->File
name it Android.mk and paste this into

LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_ARM_MODE := arm LOCAL_CFLAGS := -D"l_getlocaledecpoint()='.'" -DLUA_ANSI LOCAL_MODULE := liblua LOCAL_SRC_FILES := lua/src/lapi.c lua/src/lauxlib.c lua/src/lbaselib.c lua/src/lbitlib.c lua/src/lcode.c lua/src/lcorolib.c lua/src/lctype.c lua/src/ldblib.c lua/src/ldebug.c lua/src/ldo.c lua/src/ldump.c lua/src/lfunc.c lua/src/lgc.c lua/src/linit.c lua/src/liolib.c lua/src/llex.c lua/src/lmathlib.c lua/src/lmem.c lua/src/loadlib.c lua/src/lobject.c lua/src/lopcodes.c lua/src/loslib.c lua/src/lparser.c lua/src/lstate.c lua/src/lstring.c lua/src/lstrlib.c lua/src/ltable.c lua/src/ltablib.c lua/src/ltm.c lua/src/lundump.c lua/src/lutf8lib.c lua/src/lvm.c lua/src/lzio.c include $(BUILD_SHARED_LIBRARY) |
5. Repeat step 4. and create a file in the same jni folder called Application.mk and fill it with

APP_ABI := armeabi armeabi-v7a x86 |
By default, the NDK build system will generate machine code only for the armeabi ABI. This corresponds to an ARMv5TE based CPU with software floating point operations. You can use APP_ABI to select a different ABI – the above APP_ABI definition creates 3 libraries with support for a ARMv5TE CPU, a ARMv7 with hardware FPU instructions and x86 devices. Use all for building all ABIs.
6. Download Lua 5.3.0 source and extract it into the jni/ folder, then rename the lua-5.3.0 folder to lua
7. Back in Eclipse with a Refresh on the jni folder should update your directory and file structure like this
8. navigate with a terminal to your root project folder and type

C:\Android\android-ndk-r10d\ndk-build |
to compile liblua for Android.
9. After a successful compilation you’ll find the liblua.so libraries in the appropriate folder in the libs\ folder.

Hello – any progress on the Android Studio version? Thank you.

Android Studio uses Gradle for the build process which I didn’t had time to look at yet, sorry

Can you please upload liblua.so to github or to somewhere else. Thanks a lot.

You’ll find 5.3.0 dlls/so/etc in my VerySimpleLua repo:

Where do I put the lua files that I run with luaL_dofile?

Hi Dennis.
Am I the lucky one ;o)
I’ve almost started my own scripting engine project until I stumbled on LUA.
I’m very excited to see that you have integrated this project into Delphi.
Would there be any chance for you to compile the latest version and update GITHUB?
