Building 5.2.2.0 for Android http://www.allegro.cc/forums/view/616889 Allegro.cc Forum Thread matthew@allegro.cc (Matthew Leverton) Tue, 16 May 2017 21:32:28 +0000

I'm trying to make the leap to android. I'm trying to follow along the guide here:
https://wiki.allegro.cc/index.php?title=Running_Allegro_applications_on_Android

I'm getting to the point of actually compiling allegro for android. I've got allegro checked out from git on the 5.2.2.0 tag. Then, following the guide, I do:

mkdir Build/Android
cd Build/Android
cmake ../.. -DANDROID_NDK_TOOLCHAIN_ROOT=$TC -DWANT_ANDROID=on -DCMAKE_BUILD_TYPE=Debug -DANDROID_TARGET=android-15

After running that I get the following warnings:

-- Generating done
CMake Warning:
  Manually-specified variables were not used by the project:

    ANDROID_NDK_TOOLCHAIN_ROOT
    ANDROID_TARGET
    WANT_ANDROID

What am I missing here? Any idea why it is not recognizing the specified variables?

edit: looks like the wiki is out of date. SiegeLord pointed me to the readme. ANDROID_NDK_TOOLCHAIN_ROOT should be specified as an environment variable, and the WANT_ANDROID is replaced with a reference to the Android toolchain. So this works:

ANDROID_NDK_TOOLCHAIN_ROOT=$TC cmake ../.. -DCMAKE_TOOLCHAIN_FILE=../../cmake/Toolchain-android.cmake  -DCMAKE_BUILD_TYPE=Debug -DANDROID_TARGET=android-15
make

But then I run into the next problem:

You can also use this to build Allegro apps with Android Studio. It worked for me.

I'll give that a try. It looks like the instructions in the android readme assume older tools that are now deprecated.

edit:

Ok, I got it working! At least I have now a HelloWorld app running in a virtual android device. Thanks Elias!

I still believe it's worth updating the android README if somebody knows how to get it compiling with a more recent toolchain. Or give instructions on how to install an older toolchain. And update the wiki. I would do it myself if I knew what the correct procedure is.

The wiki is read only unfortunately.

Who owns the wiki admin ? If it's Gideon, he asked for help on it. Or maybe Thomas ?

For what it's worth, if you want to compile yourself for some reason (to fix a bug!) here's a guide that works. To build for architectures other than armeabi-v7a, repeat all steps except use one of armeabi, x86, x86_64, arm64-v8a, mips, mips64 instead.

Install JDK and Linux SDK+NDK

Compile Freetype

Compile Ogg

Compile Vorbis

Compile Allegro
