To work around this issue, you need to recompile libjpeg for iOS and change the exposed headers and function names.

Alternatively, you could download our Super Fast JPEG plugin from the Asset Store: http://u3d.as/1fxN

The JPEG plugin is based on libjpeg and libjpeg-turbo.

It's faster than Unity's EncodeToJPG() and can also run in background threads.
