osX+android: linker error

Lynx · August 23, 2011, 11:54pm

Hi,
I was trying to get oF 007 working in osX/eclipse/android configuration. Unfortunatly I got errors at linking stage about ofSoundShutdown(). As i saw, file implementing that function (ofSoundPlayer.cpp) doesn’t get compiled on andoroid targets. Funny thing is that it doesnt lead to such a problems when building with ubuntu/eclipse/android configuration.

When building with AndroidDebug there is that linking error:

  
/Developer/Piotr/android-ndk-r6/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld: warning: libcutils.so, needed by /Developer/Piotr/android-ndk-r6/platforms/android-8/arch-arm//usr/lib/libGLESv1_CM.so, not found (try using -rpath or -rpath-link)

make[1]: *** [obj/androidPolygonExample] Error 1

When building with AndroidRelease it compiles but crashes right after start of an application with LogCat like this:

Actually, adding ofSoundPlayer1.cpp shown below solved the issue, but I’m curious if there is any “cleaner” method to fix it.

  
#include "ofSoundPlayer.h"  
#include "ofUtils.h"  
  
//--------------------  
void ofSoundShutdown(){  
}

Yes this is already fixed in git. The problem is that since there’s no reference to that function directly from your code the linker doesn’t include that symbols but actually that function is called from inside OF so finally you get an undefined symbol error.

Anyway if you want to update to latest in git master it’s fixed there or as you said just defining it in your own code solves the problem
