I have a problem when I want to use the QWT library for iOS.
I compile the library QWT for iOS in architecture armv7 and arm64 with Qt 5.5.1. I checked the result (.dylib) with otool command, it's ok.
But when I put it in my soft, I have the error : symbol not found for architecture armv7/arm64.
I don't understand because it's work for Windows, Mac, Linux and Android.

Do you have already had this problem?
