Multiple definition of main for zlib

Question

I am trying to compile my cocos2d-x project, but when I run the build_native.sh I get this error:

/Users/default/Documents/Development/android-ndk-r8d/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: error: ./obj/local/armeabi/objs-debug/game_shared/__/__/Classes/3rdParty/zlib-1.2.3/minigzip.o: multiple definition of 'main'

collect2: ld returned 1 exit status
make: *** [obj/local/armeabi/libgame.so] Error 1
make: Leaving directory //.....

I can build the project without zlib, but I need it.

EDIT:

After removing example.c, I get this:

/Users/default/Documents/Development/android-ndk-r8d/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: error: ./obj/local/armeabi/tiff.a(mkg3states.o): multiple definition of 'main'

Can I exclude libtiff from cocos2d or how can I fix this?

Both your minigzip and example source code files contain a main() function. Remove the one you don't need. I'm guessing it's in example.
