Qt 5.4.1 and Raspberry 2
-
Raspberry Pi foundation started to ship PI2 this morning.
It's using a BCM2836 chip embedding a Quad Core Cortex A7 processor.
There is a raspberryPi "profile" to build qt from source on RPI.
I was wondering if someone (maybe devs) could give some information on how to rebuild Qt 5.4 for RPI2 target ?
Thanks,
Lionel.

Hi,
You should rather ask this question on the "interest":http://lists.qt-project.org/mailman/listinfo/interest mailing list. You'll find there Qt's developers/maintainers (this forum is more user oriented)
-
The hardware is almost the same, and the foundation claims the CPU is compatible. So the instructions for rPi 1 should also work for the new rPi 2.
-
You will want to change the compiler flags in mkspecs/devices/linux-rasp-pi-g++ to get properly optimized code. Everything else, including the EGL/OpenGL integration, should be the same.
In the future we will need to introduce a new device mkspec for the Pi 2.

agocs : i tried this and switched the compilation flags to :
@-marm -mfpu=neon -mtune=cortex-a7 -march=armv7-a -mabi=aapcs-linux

The build made it thru. Some qt samples work fine, but i'm encountering issues with the QML webview.For some reason it doesnt load at all. I also checked some samples using it like flickrview and the whole app starts fine but the WebView area is desperately black.
the only log i'm getting from commandline is :
@QML debugging is enabled. Only use this in a safe environment.
Failed to start " "QtWebProcess" 15"@any clue is welcome :)
