Cocos2d-x fails to compile C++ code in MacOs using ./build_native.sh

Question

I'm using android-ndk-r9b and cocos2d-x-2.1.4 under MacOs Mavericks. I was able to create the android application for cocos2d-x, but when I tried to compile the C++ code using ./build_native.sh script, the compiler get me some warnings and at the end failed.

These warnings are:

Android NDK: WARNING: APP_PLATFORM android-18 is larger than android:minSdkVersion 8 in ./AndroidManifest.xml    
Android NDK: WARNING:/Developer/cocos2d-x-2.1.4/samplecocos2dxandroid/proj.android/../../cocos2dx/Android.mk:cocos2dx_static: LOCAL_LDLIBS is always ignored for static libraries

cc1plus: some warnings being treated as errors

I'm wondering if someone has encounter similar errors, how how to revolve it?

Thanks!

Same problem here (Cocos2DX 2.1.1)

You can shut down the compiler error:

in Application.mk: APP_CFLAGS += -Wno-error=format-security

or better, solve the problem of string format, in 4 points of cocos code (as you can see in the link above):

1 - CCCommon.cpp - __android_log_print(ANDROID_LOG_DEBUG, "cocos2d-x debug info", buf); -> __android_log_print(ANDROID_LOG_DEBUG, "cocos2d-x debug info", "%s", buf);

2 - SimpleAudioEngine.cpp - LOGD(deviceModel); -> LOGD("%s",deviceModel);

3 - OpenSLEngine.cpp - LOGD(errorInfo); -> LOGD("%s",errorInfo);

4 - SimpleAudioEngineOpenSL.cpp - LOGD(errorInfo); -> LOGD("%s",errorInfo);
