Native Build Error

I have just created a new project and tried to build it and get the following error:

I have had a search around for the above issue and have reinstalled ndk and cocos2d-x which has not resolved the issue.

Thanks

Test add following code to Application.mk

APP_CPPFLAGS += -Wno-error=format-security

Thanks for your reply.

This is what it did:

Just to confirm this is now the current contents of Application.mk

APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -DCOCOS2D_DEBUG=1
APP_CPPFLAGS += -Wno-error=format-security

Just tried reinstalling NDK and cocos2d-x and it now works :smile:
