      I've tried to figure out how to force Qt and/or ./configure to not use Neon-extensions on ARM. There used to be a "-no-neon" option that is gone?

      My processor has Neon, the cross-compiler supports it etc. which seems to make Qt auto-detect it and use it, but how do I disable it? Do I have to switch compiler?

      I'm on Qt 5.3, but could transition to 5.4 if that helps.

        Hi and welcome to devnet,

        "This":https://qt.gitorious.org/qt/qtbase/commit/1b12c0608be2359baa2f96ae28b135a84abd388c patch removed the option. Looks like you'll need to fiddle with the mkspec for your target

          Aha. I looked in configure and it has sections for Neon that didn't seem to do anything, and apparently it does in fact not do anything.

          Thanks a bunch. :-)
