Error compiling Android NDK

Hello guys, I'm trying to compile the last version of the example LoadBalancing for Android NDK. I tried with Visual Studio 2010 and 2015 with VisualGDB installed, and also via cygwin + ndk-build, I don't know how to fix these errors:

NDK in cygwin :
$ /cygdrive/e/UDK/nvpack/android-ndk-r10b/ndk-build Android NDK: ERROR:jni/Android.mk:photon-cpp-static-prebuilt: LOCAL_SRC_FILES points to a missing file Android NDK: Check that jni/../../Photon-cpp/obj/local/armeabi-v7a/libphoton-cpp-static.a exists or that its path is correct/cygdrive/e/UDK/nvpack/android-ndk-r10b/build/core/prebuilt-library.mk:45: *** Android NDK: Aborting . Alto.


VisualStudio2010: Configured with the java and android sdks, and the ndk paths, everything set, even the project properties, in release configuration...
Error 13 error MSB3073: The command ""W:\CodingSoftware\VisualGDB\\VisualGDB.exe" /build "E:\PhotonCloud\SDK\android\LoadBalancing-cpp\AndroidLoadBalancing-cpp.vcxproj" "/solution:E:\PhotonCloud\SDK\android\LoadBalancing-cpp\AndroidLoadBalancing-cpp.sln" "/config:Release" "/platform:Win32"" exited with code 1. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.MakeFile.Targets 38 6 AndroidLoadBalancing-cpp Error 8 error : jni/Android.mk:photon-cpp-static-prebuilt: LOCAL_SRC_FILES points to a missing file E:\PhotonCloud\SDK\android\LoadBalancing-cpp\Android NDK AndroidLoadBalancing-cpp Error 10 error : Command-line action failed E:\PhotonCloud\SDK\android\LoadBalancing-cpp\VisualGDB AndroidLoadBalancing-cpp Error 9 error : Android NDK: Aborting .

is there anywhere a guide to compile this project properly?
I was able to compile the Windows version of LoadBalancing with Visual Studio 2015, but this is giving me headaches, so,
Thanks!.

    Hi @juaxix.

    This is likely caused by the fact that you are using NDK r10b.

    Please update to r12b and download the latest Photon Client SDK (4.1.3.3).

    4.1.3.2, which is what you probably work with right now, was the last release that required the NDK version to be either r10d or r10e.

    Sorry man, but it wont compile 4.1.3.3 with NDK r12b, just tested. What am i doing wrong?

    VS Config:

    VGBD Config:


    Error:

Stop. G:\UDK\nvpack\android-ndk-r10b\build\core\prebuilt-library.mk AndroidLoadBalancing-cpp

    I would prefer to compile using a command line than VS2010.
    In this case, can you provide the commands to do it please?

    This is what i'm doing:

    cd Libs\Photon-AndroidNDK-Sdk_v4-1-3-3\LoadBalancing-cpp E:\UDK\nvpack\android-ndk-r12b\ndk-build.cmd NDK_APPLICATION_MK=jni\Application.mk

    And this is the result:

    Android NDK: ERROR:jni/Android.mk:photon-cpp-static-prebuilt: LOCAL_SRC_FILES points to a missing file Android NDK: Check that jni/../../Photon-cpp/obj/local/arm64-v8a/libphoton-cpp-static.a exists or that its path is correct E:/UDK/nvpack/android-ndk-r12b/build//../build/core/prebuilt-library.mk:45: *** Android NDK: Aborting .

    Thanks for your time

    no success yet, i tried this:
    1) in Application.mk i set the APP_ABI := armeabi-v7a
    2) then i copied all the .a from Photon-AndroidNDK-Sdk_v4-1-3-3\Photon-cpp\lib\photon-cpp-prebuilt to a folder in the same jni folder (there is an error in the mk files because there is no OBJ files for Photon-cpp)
    3)so i can set in Android.mk:
    LOCAL_SRC_FILES := libs/libphoton-cpp-static_release_android_$(TARGET_ARCH_ABI).a
    4) then i call from a cygwin shell the command to build
    /cygdrive/g/ShivaProjects/PhotonCloud/Plugins/com.xixgames.photoncloudapi/Libs/P

    Another thing i have tried is to change the line 20 in the Android.mk (Photon-AndroidNDK-Sdk-4-1-3-3/LoadBalancing/jni/Android.mk):
    ---
    LOCAL_SRC_FILES := ../../Photon-cpp/lib/photon-cpp-prebuilt/libphoton-cpp-static_debug_android_$(TARGET_ARCH_ABI).a
    ---
    so, they actually point to the prebuild libs.

    Ok , I was able to compile it using OSX and changing the line of the Android.mk:

    Hi @juaxix.

    The "access denied" error might come from unzipping the downloaded folder with Windows itself, which blocks all unzipped files from a downloaded zip-archive, so that you need to manually unblock them. This can be prevented by using a 3rd party program to unzip the archive, for example 7zip.

    I can reproduce the obj folder issue when trying to build the LoadBalancing-cpp solution. We will fix this for the next release
    However it is not necessary at all to rebuild LoadBalaning-cpp yourself, when you do not modify its source. You can just use the prebuilt libraries that ship with the SDK.

    Note that LoadBalancing-cpp is not a demo or example project, but part of the Photon Client libraries and can normally just be used as is. For demo projects on how to use the libraries please look inside the "Demos" folder.

    ok, i see that if i use 7zip this problem is gone.

    I can't use the compiled lib, everything works in iOS but not in Android.
    I have this error when i try to use the compiled .a with the loadbalancing+common-cpp+photon-cpp libs (.a) inside a plugin.a for my game:

    looks like the Photon libs are not a valid elf format, why is that?

    Hi @juaxix.

    Yes, of course it is not a valid elf file. If it was, then the file ending would be .so. It is a static library, not a dynamic one, so you must link against it statically.

    Hi @juaxix.

    Sorry, but I am afraid I have never seen this error before.

    My suggestion is to compare your Android.mk and Application.mk with the ones from the demos inside the SDK to see what you are doing differently.
  • juaxix

    Ok, I can do that.
    Ah, how can compile the .a as .so?

    You can't, at least when it comes to Common-cpp and Photon-cpp. What you could do is writing your own wrapper .so lib that exports all public functions of the .a, which it wraps, in its own interface.
    You could rebuild LoadBalancing-cpp and Chat-cpp as .so, as they are open source, but o course you would need to export all public functions then, so you would need to do quite a bit of merging when updating the libs later.

    My recommendation is to just let your app link the .a files directly, as I can't see any advantage in using .so files instead, that would be big enough to justify the additional work involved.

    Ok, I'm creating the .so now, but when i try to build ,if i use the android-ndk build for r12b and 4-1-3-3 android sdk, this error appears:

    Hi @juaxix.

    Please change
    APP_STL := gnuport_static
    in your Application.mk into
    APP_STL :=c++_static

    4.1.3.3 requires the use of libc++.

    Please note that this is about to change. Starting with 4.1.4.0 we will require the following 2 settings in Application.mk: 
    APP_STL := gnustl_static
APP_CPPFLAGS := -std=c++11
    instead.

    You can have a look at the Application.mk and Android.mk file of any of the demos inside the SDK for an example of a working configuration.

    Oh, thanks @Kaiserludi ,it compiles now, and the next error is really large and weird. (line 1917)

    i just want to test if i can load the .a from a java using a c++ jni wrapper

    Regarding your error:
    I don't see any obvious problems in your code that could cause this.
    My suggestion is to track down what exactly is causing the problem.

    Does myListener::connect() crash when being called from one of the provided demos? If not, then you need to find out, what your testapp does differently from our demos.

    Thanks for the correction @Kaiserludi .
    Well, finally i got it to compile your demoLoadbalancing project, the problem was that the directory was too deep in the hard-drive and it could not successfully copy files, I moved all to E:\.
    Testing your demo it appears: received error 1030 from client and then 1040 and disconnect. Something wrong?, before I go forward and try to integrate my changes into loadbalancing for android again and recompile,...

    I think i'm very close to achieve it @Kaiserludi ! . A little more help :smile:
    I was able to run with my code and test the game with your android demo and my loadbalancing code, as you see in the screenshots:

    Hi @juaxix.


    Testing your demo it appears: received error 1030 from client and then 1040 and disconnect. Something wrong?,

    It seems you have solved that by now?
    Getting these errors on trying to connect usually means the socket can't reach the server at all, which is usually caused by having no internet connecting, getting blocked by a firewall or trying to connect to an incorrect address, at which no Photon server is running.

    Regarding the undefined references to the stdlib:
    Well, from your log it looks like not the app, but the PhotonCloudAPI lib fails to build, but the .mk files that you show seem to be the ones for the app.

    Yes, I added my code to the loadbalancing in the demo project, recompiled and it worked :)

    Yeah, what I was showing is the built of the app (apk of the game), with the already built plugin PhotonCloudAPI.a, but now that you mention it, i think i'm not doing it right :(

    I'm using a script to extract all the .o and then add the objects in the .a (I can't use the ar rcs option because the photon .a are not elf files).

    C:\Games\sdks\android-ndk-r12b\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-ar -x libcommon-cpp-static_debug_android_armeabi-v7a.a
    C:\Games\sdks\android-ndk-r12b\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-ar -x libloadbalancing-cpp-static_debug_android_armeabi-v7a.a

    And this is the Makefile for the engine plugin + photon libs:
    http://pastebin.com/RgpUMj1F

    You know, originally, the engine generates an android project with that Makefile and with only the option of rcs ( $(AR) -rcs $(TARGET) $(OBJECTS)) ,so i changed it to be able to compile, with no success yet.

    Ok, I'm compiling only for the arm-v7a with:
    make ../../Contents/Android/PhotonCloudAPI_Android_arm_v7a.a


    these are the instructions of the makefile:
