@mariusmssj

thank you for the screenshots. i will try that in a while.

in the meantime, does anyone know how i can build a console application for Sailfish that uses Qt? i only want to use certain Qt classes with no UI.

i must be missing something in my .pro file as the compiler is complaining about unresolved symbols? i created a new project under Qt Creator as C++ application.

i also tried creating a SailfishOS project and in main.cpp I have my code added in. I commented out

//Sailfish::showView(view.data());
//return app->exec();
same thing. still complaining about unresolved symbols. i am trying to use QFeedbackHapticsEffect and QFeedbackActuator. my #include section looks like this

#include <QtFeedback/QFeedbackActuator>
#include <QtFeedback/QFeedbackHapticsEffect>
#include <QGuiApplication>
#include <QQuickView>

wait a sec. i don't see Mer ARM Device in the list. I only see Generic Linux Device and Mer Emulator Device.

tried updating the SDK via control panel (yes, i develop on Windows) and it only found an updated maintenance tool.

edit: i think i'll uninstall the SDK and download a copy. i had mine installed before Mer ARM Device support was added sometime around mid Dec last year.

Which symbols do the linker complain about? Probably something missing to the QT or QTPLUGIN variable in the .pro file.

it's not even at the linker yet....

from twitter:
@locusf: Sailfish SDK Qt Creator sources are now online in: https://t.co/H0bqRKHQpD Might reveal a lot of interesting stuff.

Trying to build on device, qt5-qmake, qt5-qtconcurrent-devel and qt5-qtcore-devel all install fine. Qtgui and widgets sadly don't:

Code:
Fatal error: qt5-qtgui-devel-5.1.0+git31-1.12.8.armv7hl requires qt5-qtopengl-devel, but this requirement cannot be provided
qt5-qtwidgets-devel-5.1.0+git31-1.12.8.armv7hl requires pkgconfig(Qt5Gui), but this requirement cannot be provided
qtgui needs qtopengl that needs libEGL, the only similar pckg is mesa-llvmpipe-libEGL, but that conflicts with libhybris. Anyone has an idea how to get it to compile/working?

Here be dragons.

As a whole stack, we build against Mesa's libEGL, but at runtime, we then pick a different - hardware-dependent libEGL implementation (which exactly depends on what hardware we're running on: on the Jolla, it's libhybris', on the N9 there's ti-omap3-sgx-wayland-wsegl's wrapper around the SGX drivers, etc). They're all - obviously - ABI/API compatible.

On the whole, I'd just recommend not building on device, because there is a way-too-easy chance you can wipe out your EGL libraries if you accidentally answer "yes" at the wrong prompt.

Why not use the SDK, out of interest?

Couple of reasons. First is pleasure to have a fully fledged PC in your pocket (like when flashing one N900 with another, who needs desktop, right?). Second, most of my free-to-tinker time is on bus rides to/from work and similar. If I need a quick fix/modification I can perform it on the go instead of waiting 10h (if I get the idea on the morning ride) to see if it works. Not expecting to have a full build/deploy-to-harbour env on the phone, but for a quick recompile I hope we can make it work (especially now with HWKB OH)


edit: good news, at least tohkbd can be tweaked/tinkered with on the go, qmake generates Makefile correctly, make succeeds, no need for qtcreator
