Errors building SFML for Android

[LunaRebirth]

Following https://github.com/SFML/SFML/wiki/Tutorial:-Building-SFML-for-Android, I was successfully able to use the cmake command.

When I use mingw-32 make, I receive these errors:

How can I fix this?

NOTE:
Using make instead of mingw32-make gives the same result.

[AlexAUT]

Are you using the newest NDK?

If so you have to add "#include <GLES2/gl2platform.h>" before the gl2ext.h in SFML/include/OpenGL.hpp. Also you cannot use libc++ with the newsest NDK.

P.S.
You can also use this PR which fixes the build issues and supports libc++ (read the description of the PR, the build process is a tiny bit different)


AlexAUT

[LunaRebirth]

No I'm using ndk r9c. Am I able to fix this without changing versions? My Android project uses it, and I'm just trying to add SFML's audio library.

[AlexAUT]

Have you tried to include gl2platform before gl2ext as I said above? Maybe it is also a problem with older NDK version.


AlexAUT

[LunaRebirth]

Wow, thanks. That fixed it.

Appreciate your help.

[LunaRebirth]

New errors.

I can build SFML with

Code: [Select]

cmake -DANDROID_ABI=armeabi -DCMAKE_TOOLCHAIN_FILE=../../cmake/toolchains/android.toolchain.cmake ../.. -G "MinGW Makefiles" -DANDROID_STL=stlport_shared
which works fine, but then when I compile the android example, I get a bunch of errors like:

Ideas would be helpful.

[AlexAUT]

You can upgrade your ndk to r12 to use libc++ with sfml master. Or use the latest ndk Version and the PR from above.

It shouldn't affect your code at all.

Ndk r9 is very old i am not sure if libc++ was somewhere complete and stable at the time. You could also try gnustl (but look at the license) which may work in r9 with a descent STL support

Awesome.

Lastly, the example project builds and runs on my phone just fine.
But when I try to use just SFML's audio in my project, I get a crash right as sf::Music::openFromFile is called.

Here is my trace:

I only added to my Android.mk file:

The example project does include audio, and if this works something in your mk file is wrong. But we cannot tell without seeing it

Ideally I'd use only sfml-audio. Either way, the program still crashes at the same spot.

I tried making sfml-main in LOCAL_WHOLE_STATIC_LIBRARIES, but then got a conflict error:

[AlexAUT]

Sadly you cannot use sfml-audio only out of the box. But have a look at sfmlActivity under src/main/. If you call this function yourself

loadLibrary("openal", lJNIEnv, ObjectActivityInfo);

you might be able to use sfml-audio as standalone. But I am not sure if this will work.

Another option could be loading openal  in your Java Activity, sadly I don't have the time to try it out and test it.

System.loadLibrary('openal')

AlexAUT

[LunaRebirth]

Unfortunately it doesn't seem to work too well with Irrlicht and I'm getting a little frustrated that this is such a big process for audio.

Thanks for your help.

I copied a lot of that sfmlActivity file like so:

Code: [Select]

#ifdef _IRR_ANDROID_PLATFORM_
namespace {
    typedef void (*activityOnCreatePointer)(ANativeActivity*, void*, size_t);
}

const char *getLibraryName(JNIEnv* lJNIEnv, jobject& objectActivityInfo)
{
    // This function reads the value of meta-data "sfml.app.lib_name"
    // found in the Android Manifest file and returns it. It performs the
    // following Java code using the JNI interface:
    //
    // ai.metaData.getString("sfml.app.lib_name");
    static char name[256];

    // Get metaData instance from the ActivityInfo object
