cocos2d-x-2.1.4 : error: format not a string literal and no format arguments [-Werror=format-security]

Question

I am working on a game on cocos2d-x-2.1.4, however, when I try to build it on Android, it failed with the error: format not a string literal and no format arguments [-Werror=format-security] on the file CCCommon.cpp

However, when I check the offensive line, it is totally fine. The file also build fine and always been fine when I build for WIN32 and iOS with Visual Studio and XCode..

The error log is as follows:

cc1plus.exe: some warnings being treated as errors

Answer 1

Note that cocos2d-x-2.1.4 may not be compatible with ndk-r9, have you try out r8e instead?

You can also put this in your Application.mk to disable treating those warnings as errors: APP_CFLAGS += -Wno-error=format-security

you have to defice in you Android.mk following LOCAL_DISABLE_FORMAT_STRING_CHECKS := true
