I am trying to use libpng within my app which also contains a Unity3D demo. Every since adding Unity3D to the project our use of libpng broken. It complains about incompatible versions. So we stopped linking against our static libpng. Now merely using the wrong headers in libpng causes this same problem. So I need to match the headers exactly to the version of libpng Unity3D is currently using. This should be quite simple except that Unity does not document anywhere the version of libs they are using.
So what version of libpng is Unity3D 4.3.2 using?
