Crash when run the CppTests in Eclipse

cocos2d-x C++

Hello all,

When I run the CppTests, it crashes and the logcat shows these errors.

Do you know what’s wrong?

Test program crashes when try to run on android

You need to compile C++ code by ‘build/android-build.py’ before run the project in eclipse.

Hi,
I know this is an old post but I am having the same issue and unfortunately i dont have “android-build.py” in the android project folder of cpp-empty-test. I am using Coco 3.13.1.

Can you please suggest any thing?

Thanks,
Abe

Hi @Abe_Fork,

Instead of android-build.py you can use Cocos Command.

Hi @Gurudath

Thanks for your response. I tried compiling the cpp-empty-test with Cocos Command as

cocos compile -p android -m release

and it give the following errors:

Android NDK: ERROR:C:/Android/android-ndk-r9d/sources/cxx-stl/gnu-libstdc++/Andr
oid.mk:gnustl_static: LOCAL_SRC_FILES points to a missing file
Android NDK: Check that C:/Android/android-ndk-r9d/sources/cxx-stl/gnu-libstdc++
/4.9/libs/armeabi/libgnustl_static.a exists  or that its path is correct

I looked into the path the 2nd error shows and I don’t have 4.9 folder in there. :frowning: only 4.6 and 4.8
Here are the tool versions I am using.

ADT: adt-bundle-windows-x86_64-20130917
NDK: android-ndk-r9d
Apache Ant: apache-ant-1.9.7
Cocos: cocos2d-x-3.13.1
Python: python-2.7.6.amd64
Installed JDKs: jdk-7u79-windows-x64 and jdk-8u111-windows-x64

Is there anything else I need to install?

Thanks,
Abe

@Abe_Fork,

Can you use Latest version of NDK & Check once.
Am using android-ndk-r10e Version. I have this file (sources/cxx-stl/gnu-libstdc++
/4.9/libs/armeabi/libgnustl_static.a) exists inside NDK.

Hi @Gurudath,

Thanks for the reply. I tried cocos 3.12 and it worked. But now I am having a hard time linking our own “.a” file for android.
But I am looking into it. Since it is not related to this topic, I am not willing to give a head ache for this issue here :slight_smile:

Thanks again.
