    Hi and welcome to devnet,

    Are you trying from OS X or from Windows ? In either case, I'd recommend the use of e.g. VirtualBox and make a virtual machine with Linux on it (e.g. Kubuntu). That will make the cross-compiling way easier.

    Yes I am working on Windows 10 - I would prefer not to add yet another system (real or Virtual)!

    I tried looking for msys on Windows 10 - but no success so far!

    Thank-you for the thought - as a real last resort!

    David

    Thank-you for the advice on =reflection:

    I have installed Ubuntu 14.04 LTS (in Parallels).
    I installed the QtCreator package which came with it.
    I can ssh to my raspberry.

    But when I tried to set up QtCreator to cross compile (Tools/Options/Devices) it failed to test connect to my Pi - never had this problem before in previous attempts to set up a cross compiler e.g on OSX and Windows! )

    OK - so I removed it and went to the Wiki 'Install QTCreator on Ubuntu' - I now find that Ubuntu will not execute .run files, again a google search reveals a large number of 'do this or that' none of which work (for me)!

    I feel I am running out of options!

    Might be a silly question but: can you ssh from OS X or from Ubuntu ?

    What error are you getting from Qt Creator when connecting to your Pi ?

    I do apologise, I should have included this before - I get

    SSH connection failure: SSH Protocol error: Server and client capabilities don't match. Client list was: aes128-cbc,3des-cbc.

    Ok, sounds right, what about Qt Creator ? Which version is it ?

    I am just rebuilding the Linux system, I will let you the exact details when that has finished - it was the QtCreator which comes with the Ubuntu 14.04 package library!

    Might be a bit old, I'd try with 3.5.1 before anything else.

    Hmmmm.

    I am running UBUNTU 14.04LTS in Parallels on a Mac-mini

    The Mac Mini CPU is an Intel Core 5 (which I would assume is an i386 and not an AMD)

    The files installed for qtcreator as listed in packages.ubuntu.com are for an AMD64 machine (/usr/lib/x86_64_linux_gnu/...).

    Also the ubuntu list shows that Qtcreator after 3.0.1 are under development.

    This does not look right!

    In any case I have just seen (doc.qt.io) that Qt 5.0 no longer includes a Windows Platform, and suggests that I should wait for Wayland

    I think all this means that I should go elsewhere, so thank-you for you time and interest, it is much appreciated.

    David

    Core i5 is for sure x86_64 and it can execute i386 binaries as well.
    Because x86_64 was invented by AMD and later implemented by Intel as well it is often called AMD x86_64.
