Qt on OSX cross compiler for PI
-
I am having problems install qtCreator on OSX (Capitan) - I followed the attached script
http://www.welzels.de/blog/en/arm-cross-compiling-with-mac-os-x/comment-page-1/
All OK until I get to installing QtVersions which require file:
/usr/local/Trolltech/Qt-4.8.6-raspi/bin/qmake – Raspberry Pi
Alternatively, is there an official Qt 'install procedure' which I can use?
Thank-you

Do you mean you don't have /usr/local/Trolltech/Qt-4.8.6-raspi/bin/qmake?
As far as I know there is no official Qt build for PI, you have to build Qt from sources. -
@DavidHux As I said there is no Qt build for PI.
Download Qt source code and build it for PI.
See here for details: https://wiki.qt.io/RaspberryPi_Beginners_Guide -
Thank-you for the info.
Since I do not run Linux on a PC i thought my best chance would be to use the following script:http://visualgdb.com/tutorials/raspberry/qt/embedded/
linked to by the QT Raspberry Pi Beginners Guide (and I therefore thought would have some hope of working)
All went well (at least no failures) until I got to the step:
7.0 Launch the msys shell from the MinGW toolchain by running <sysgcc>\MinGW32\msys\1.0\msys.bat:
This failed - with an sh.exe stopped working - no windows help provided - but last message in terminal window was`:
204 [main] sh5876 sync-with`-child: *** child state waiting for longjmp
sh: fork: Resource temporarily unavailableand the us.stackdump ended with (probably corrupt stack)
a google on msys indicates a lot of problems (is this a W10 problem?)
Help!!

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.

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
Setting up QtCreator to cross compile (Tools/Options/Devices) it failed to test connect to my Pi
SSH connection failure: SSH Protocol error: Server and client capabilities don't match. Client list was: aes128-cbc,3des-cbc.
Server list was aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm@openssh.com,aes256-gcm@openssh.com,chacha20-poly1305@openssh.com.Device test failed.
Thank-you for your interest

What Linux flavor are you running on the Pi ?
-
Ok, sounds right, what about Qt Creator ? Which version is it ?
-
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.

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.
